POLYESTER PUTTY WITH WHITE FIBER + CATALYZER

What is POLYESTER PUTTY WITH WHITE FIBER + CATALYZER and why choose it

POLYESTER PUTTY WITH WHITE FIBER + CATALYZER by Kemipol is a two-component polyester filler reinforced with white fibers, intended for professional repair of dents, cracks and structural defects on metal and composite surfaces. Based on typical Kemipol polyester putty technology, it is mixed with a peroxide hardener (catalyzer) to deliver a fast-curing, highly resistant repair layer. This description is based on general information for Kemipol/AkzoNobel polyester putties and similar glass-fiber reinforced fillers and may not exactly match the official technical data for this specific product.

Choose this putty when you need a high-build, fiber-reinforced repair with good mechanical strength and adhesion on steel, galvanized steel, aluminium and polyester surfaces, and when you value easy application and sanding once fully cured.

Main features

• Two-component polyester system to be mixed with a separate catalyzer (peroxide hardener) before use.
• White fiber reinforcement for increased mechanical strength, reduced shrinkage and better bridging of holes, cracks and heavily damaged areas (information inferred from typical "polyester putty – fiber" products, not specifically verified for this exact code).
• High build capability to fill deeper dents and surface irregularities in fewer passes compared with standard smooth putties (unverified, inferred from standard fiber putty behaviour).
• Good adhesion on common refinish substrates such as steel, galvanized steel, aluminium and polyester/fiberglass surfaces, in line with standard Kemipol polyester putties (not individually verified for this exact product).
• Fast curing after mixing with the catalyzer, allowing sanding typically within tens of minutes at room temperature (approximate, not product-specific).
• Designed for professional use in automotive, nautical or industrial maintenance where structural reinforcement of the repair area is required (scope inferred from similar Kemipol and fiber-reinforced polyester putties).

Technical specifications

The following data are typical characteristics of Kemipol/AkzoNobel polyester putties reinforced with fibers and are provided as indicative only. Exact values for POLYESTER PUTTY WITH WHITE FIBER + CATALYZER are not verified and may differ. Always check the official Kemipol technical data sheet and safety data sheet before use.

• Chemical nature (unverified): unsaturated polyester resins with mineral fillers and fiber reinforcement, cured with an organic peroxide hardener.
• System: 2K (base putty + catalyzer).
• Mixing ratio (typical, not product-specific): around 100 parts putty to 2–3 parts peroxide hardener by weight, depending on temperature and manufacturer guidelines.
• Suitable substrates (indicative): prepared steel, galvanized steel, aluminium, polyester/fiberglass and compatible epoxy or polyester primers in good condition.
• Application tools: putty knife or spreader on clean, sanded and degreased surfaces.
• Drying/curing (approximate, not verified): workable and sandable after roughly 20–30 minutes at 20 °C, depending on layer thickness, hardener level and ambient conditions.
• Recoating (general rule): can usually be sanded and then overcoated with compatible primers and topcoats once fully cured and dust-free.

Applications and use cases

• Automotive body repair: filling deeper dents, rust damage cut-outs, weld seams and structural imperfections where a reinforced filler is preferred before applying finer finishing putties.
• Nautical and marine repairs (inferred from Kemipol polyester putty range): repair of hulls and superstructures made of steel or fiberglass where high build and reinforcement are needed.
• Industrial maintenance: restoration of machinery covers, panels, tanks and structural elements made of metal or polyester laminates.
• Fiberglass and composite work: rebuilding damaged edges, corners and areas where a more rigid, fiber-containing putty offers better stability than a standard smooth filler.
• Base layer before finishing putty: used as the structural filling layer, followed by a finer polyester finishing putty to eliminate small imperfections and pinholes.

FAQ – POLYESTER PUTTY WITH WHITE FIBER + CATALYZER

1. Is this product ready to use from the can?

No. POLYESTER PUTTY WITH WHITE FIBER + CATALYZER is a two-component system. The base putty must be mixed with the supplied catalyzer (peroxide hardener) in the recommended ratio before application. The exact ratio for this product is not verified and should be confirmed in the official Kemipol technical data sheet.

2. On which surfaces can I apply this putty?

Based on typical Kemipol polyester putties and fiber-reinforced fillers, it is generally suitable for properly prepared steel, galvanized steel, aluminium and polyester/fiberglass substrates. As the exact compatibility list for this reference is not confirmed, always follow the manufacturer instructions and perform a small adhesion test where necessary.

3. How long does it take before I can sand the repair?

For many 2K polyester fiber putties, sanding is usually possible after around 20–30 minutes at 20 °C, depending on the amount of hardener, film thickness and ambient conditions. This timing is indicative only and has not been specifically verified for POLYESTER PUTTY WITH WHITE FIBER + CATALYZER.

4. Can I apply it over existing paint?

In professional refinishing, polyester putties are usually applied over sanded bare metal, fiberglass or compatible primers. Application over old paint is generally limited to well-adhered, thoroughly sanded coatings, if allowed by the manufacturer. The exact recommendation for this product is not verified; consult the official Kemipol documentation and always prepare the surface as specified.

5. Is this product suitable for plastic bumpers?

Most glass- or fiber-reinforced polyester putties are not recommended on flexible plastics because of the difference in flexibility. Usage on rigid plastic components must be explicitly approved by the manufacturer. There is no confirmed information that this Kemipol product is suitable for plastic bumpers, so application on flexible plastics should be avoided unless the official data sheet states otherwise.

6. How should I mix the putty and catalyzer?

Normally the base and the catalyzer are mixed on a clean mixing board using a spatula until a uniform colour is achieved, avoiding air entrapment. Many Kemipol polyester putties specify around 2 parts hardener per 100 parts putty by weight, but this ratio has not been specifically confirmed for this product. Always follow the exact mixing instructions provided by Kemipol.

7. Can I apply several layers for very deep dents?

For deep or wide repairs it is common practice to apply fiber-reinforced polyester putty in multiple thinner layers, allowing each to cure before applying the next, to minimize internal stress and shrinkage. This is a general recommendation for polyester fiber putties and not a product-specific instruction; verify with the official technical data sheet.

8. What kind of paint system can be applied on top?

Once fully cured and sanded, polyester putties are typically overcoated with compatible epoxy or polyester primers and then with the chosen topcoat system. Exact compatibility and recommended primers for POLYESTER PUTTY WITH WHITE FIBER + CATALYZER are not confirmed here and must be checked against Kemipol’s official documentation.

9. How should I store the product?

In line with usual storage conditions for polyester putties, keep both the base and the catalyzer tightly closed in their original containers, in a cool, dry and well-ventilated place, away from heat sources, direct sunlight and ignition sources. Storage temperature and shelf life for this specific Kemipol product are not verified; refer to the manufacturer’s data.
