Koch-Chemie Ceramic Effect Polish "Cep" Premium Foam Polish 20000ml

Foam Polish Cep for Hydrophobic Shine from the Car Wash

The foam polish Ceramic Effect Polish "Cep" is a brush-activated premium concentrate for automated car washes and gantry systems. With only 5 to 10 milliliters per vehicle, it creates a protective film that immediately breaks and repels water. Not for hand or touchless washing, not for interior materials like leather or upholstery.

Koch-Chemie Ceramic Effect Polish "Cep" is a brush-activated foam polish from the professional system range for the final stage of a car wash. The active ingredient is an amino-functional siloxane polymer – in simpler terms: a flexible silicone with adhesive nitrogen anchors that clamps itself to the clear coat as soon as brushes or Swingtex strips work it into the paint bed. For you, this means: the car leaves the facility with a clear beading effect until the next wash.

• Microdosing 5 to 10 ml per vehicle. A 20-liter canister is sufficient for up to 4,000 washes. Sonax Hypercoat requires 10 to 15 ml per car, Eurodet Polifoam 50 to 70 g – Cep uses 2 to 10 times less material and saves storage space in the chemical room.
• Paint, glass, and equipment are protected simultaneously. The siloxane layer not only impregnates clear coat, glass, and plastic attachments, but also the brushes and Swingtex strips of the equipment itself. Practical result: approximately 20 percent longer service life of the washing materials.
• Maximum 5 minutes exposure time, up to 30 °C paint surface. Within this window, Cep does not attack paint, chrome, or plastic. This means in car wash operation: if the conveyor belt stops for more than three minutes, spray the vehicles with high pressure, otherwise polymer spots will occur.

Practical tip from Detailing1: From our experience, we see the same pattern in every second car wash that switches to Cep: the old diaphragm dosing pump is still calibrated to 30 to 50 ml per wash, because the previous polish was dosed that way. The result: greasy streaks on the windshield, wipers chattering, the hydrophobic effect dissipating. The professional rule: absolutely recalibrate the pump to 5 to 10 ml before the first Cep run and check the dosing valve after 200 washes. If the conveyor belt stops for more than three minutes, additionally spray the vehicles with high pressure – polymer burn-ins above 30 °C paint temperature are the most expensive warranty issue a car wash operator can have.

Cep only works when the brushes massage the paint

The foam arch must be positioned before the final brush or Swingtex station, otherwise the water film will not break. Touchless systems provide too little mechanical friction for Cep, and the hydrophobic effect is completely absent.

The aminosiloxanes are not passive layer builders, but only react under pressure. The nitrogen anchors of the polymer grab the clear coat surface like small magnets, and only when Swingtex or PE brushes press the foam into the paint bed do the siloxane chains align parallel and build the hydrophobic layer. This means for you: without paint massage, the car remains wet after the drying arch, the blower has to run longer, and the electricity meter increases.

The dosing pump dispenses between 5 and 10 milliliters per vehicle - no more. In older systems that were run with 30 to 50 ml for other polishes, the ratio of foam pattern and residual amount on the window would otherwise collapse. A second adjustment screw: the paint surface must remain cool, ideally below 30 °C. In direct summer sun in the exit area, the foamed Cep can dry before the brushes arrive - this leaves polymer spots that can only be removed with the abrasive polish Fine Cut F6.01.

Anyone setting up a new service station completely covers the full car wash workflow with the Koch-Chemie range: alkaline pre-wash, neutral main shampoo, Cep in the foam arch, high-pressure rinsing, high-performance blower. This sequence is also the prerequisite for the system to comply with industry specifications for paint, plastic, and chrome compatibility.

The surfactant system contains a non-ionic auxiliary – simplified: a mediator between the water-repellent silicone and the water. The surfactant keeps the aminosiloxanes in a foamable solution so that the foam image remains stable. In everyday use, you notice this in the visual foam arch, which both car wash operators and end customers expect. If the foam becomes too loose or disintegrates too quickly, the surfactant auxiliary system is usually overdosed – consequence: Cep is diluted too quickly on the paint surface, the hydrophobic effect becomes poor and the beading pattern after drying is disappointing.

Cep protects, but does not correct micro-scratches

The Cep layer is a sacrificial layer until the next wash, not a 9H coating. If you want permanent paint protection, combine Cep with the real Ceramic Allround C0.02 ceramic coating as a base underneath.

Cep is perfectly compatible with clear coat surfaces, painted aluminum rims, glass, plastic attachments, and rubber seals. Interior materials are strictly forbidden: leather, Alcantara, upholstery, and open-pore plastics absorb the aminosiloxanes irreversibly. On upholstery, this results in stains; on leather, a slippery surface – both are irreversible. Raw, un-clear-coated aluminum is also excluded because Cep has no cleaning acid effect and does not dissolve brake dust.

In a competitive comparison, micro-dosing becomes the trump card. Sonax Hypercoat needs 10 to 15 milliliters per vehicle, Dr. Stöcker CP900 even 10 to 20, Eurodet Polifoam Red pulls 50 to 70 grams per car through the pumps. In practice, this means: for 1,000 washes per month, a system with Cep consumes between five and ten liters of concentrate, while with Polifoam Red it's 50 to 70 kilos of material. These are containers, logistics, storage space, container changes in shift operation – micro-dosing is not just about material costs, it's about storage and personnel efficiency.

The most common application error in practice: conveyor belt stoppage with the foam arch running. If the system stalls, the Cep remains on the paint for more than five minutes. The industrial compatibility certificate from the German Association of the Automotive Industry is valid for exactly 300 seconds – translated: a TÜV-like industrial seal that does not attack paint, chrome, and plastic within the defined time window. Beyond that, polymer burn-ins threaten, especially in summer. Solution: SOP for personnel regarding conveyor belt stoppage, high-pressure emergency spray-off in the drying zone.

For differentiation, the simple if-then logic applies. If automated system with paint massage → Cep. If hand wash or detailed care → the less concentrated Ceramic Effect Shampoo "Ces" with the same polymer family. If paint correction is necessary → abrasive or anti-hologram polish with a polisher. Cep does not replace machine polishing – it is the final sealant, not an abrasive or cleaner.

Cep is formulated as a pure B2B concentrate. In the system room, protective gloves and safety goggles are mandatory, and an emergency eyewash must be within reach. In the process water circuit, Cep is unproblematic: the micro-dosing of 5 to 10 ml keeps the active ingredient concentration in the recycled water below the inhibition threshold of the treatment microorganisms. This is also why Koch-Chemie explicitly approves Cep for biological process water treatment plants - if overdosed, this approval is void.

20-liter canister for professional systems, not for the garage

The target group for Cep foam polish consists of car wash operators, gantry systems, car dealerships with their own facility, and specialized B2B detailers. For hobby detailers without a dosing pump, the canister is simply not manageable.

The 20-liter container size is designed for systems with diaphragm dosing pumps. An operator of a gantry system in a car dealership can cover three to six months with one canister, depending on the frequency. A self-service car wash benefits only if the dosing technology is precisely enough calibrated – most self-service foam arches operate in the 30 ml range and are therefore outside the Cep specification.

An established best practice from the professional camp: use Cep as a booster on vehicles that are already sealed with a genuine ceramic base like Ceramic Allround C0.02 or Ceramic Body Cb0.01. The gentle aminosiloxane enrichment reactivates the beading effect of an older coating layer that has become dull due to road film. A fleet with Cb sealing plus regular Cep application typically maintains its showroom shine six to nine months longer than a fleet without this combination.

When recalibrating an old system, it's best to plan the first 50 washes as a test batch: start the pump at 7 milliliters, check the beading pattern after the drying arch on 10 random vehicles. If the water runs off in sheets instead of clear drops, either the foam arch pressure is insufficient or the brush contact time is too short. Only then adjust the dosage. Translated, this means: the chemistry is not the lever, but the mechanics of the system. The polymer concentration in Cep is already perfectly adjusted - everything you do as a system operator optimizes the activation mechanics.

The trick the manufacturer's brochure doesn't mention: the polymer layer impregnates the brushes of the system so strongly that their service life increases by about 20 percent with consistent Cep use. For a typical car wash with two sets of gantry brushes per year, this saves a four-figure sum in brush replacement and service work – the biggest hidden economic benefit of this concentrate and the real reason why professional systems rarely give up Cep once they have properly calibrated their pumps.

Application of Koch-Chemie Ceramic Effect Polish Cep

Calibrating the system and positioning Cep in the workflow

The diaphragm dosing pump of the car wash system must be set to 5 to 10 milliliters per vehicle. Older systems that ran with 30 to 50 ml for other polishes must be recalibrated before the first Cep run - otherwise streaks will appear on the windshield and paintwork.

Position the foam arch so that a brush or Swingtex station follows after application. The paint massage by brushes is a prerequisite for polymer activation - without mechanical friction from the brushes, the hydrophobic effect will not occur, and the car will leave the system wet.

Workflow in the system: alkaline pre-wash (e.g., Active Foam Af) → neutral main shampoo → Cep in foam arch 5 to 10 ml → brush or Swingtex massage → high-pressure rinse → high-performance blower. Ideally, paint surface should be below 30 °C, never apply in direct summer sun in the exit area - otherwise polymer spots are likely.

Maximum dwell time of 5 minutes in accordance with the industrial compatibility requirements of the German Association of the Automotive Industry. If the conveyor stops for more than three minutes, vehicles must be freed from Cep by emergency high-pressure spray, otherwise polymer burns can only be removed with the abrasive polish Fine Cut F6.01.

Notes: Cep is exclusively designed for automatic car wash systems with a dosing pump - not for hand or touchless washing, not for interior materials such as leather, Alcantara, or upholstery, not for raw aluminum without clear coat. In the system room, protective gloves, safety glasses, and an eyewash station within reach are mandatory equipment. Store frost-free between 5 and 30 °C. In a 20-liter canister as a pure B2B concentrate. Explicitly approved for biological process water treatment systems - this approval only applies to microdosing of 5 to 10 ml per vehicle; it will be voided if overdosed.
