GELCOAT & TOPCOAT

Polyester gelcoats/topcoats are specially formulated resins designed to protect composites from UV, weathering, and chemicals while providing a smooth surface. They can be applied with a brush or spray gun and are available in various grades such as orthophthalic, semi-iso, iso, iso-npg, and vinylester gelcoat.

MCtechnics has invested in a coloring machine, enabling us to deliver colored gelcoats/topcoats based on ISO and ISO-NPG with a corresponding RAL color within 24 hours in the Benelux region. In addition to this standard range, we offer various modified gelcoats to meet specific requirements:

• Fire retardant gelcoat: to be used with a fire retardant resin system – certificate available on request.
• Abrasion-resistant gelcoat: for applications exposed to weathering and abrasion.
• Sanding gelcoat: used for parts requiring sanding before painting.
• Barrier coat: designed to prevent print-through.
• Tooling gelcoat: vinylester gelcoat specially designed for tooling applications.
• Epoxy-compatible gelcoat: based on polyester chemistry, offering UV resistance comparable to polyester but compatible with epoxy resin. Please contact our technical team for specific processing methods.
• Additionally, epoxy gelcoats have been developed in combination with epoxy resin systems, providing high abrasion resistance and available in a wide range of products.
