EP-Gelcoat colourless NOVA

EP Gelcoat colourless NOVA for Hardener S and Hardener L

• New, optimized formula for EP gelcoat*
• Translucent (not transparent)
• Can be dyed with colour pastes
• Thixotropic (non-drip)
• Manufactured under vacuum, so optimally free of air bubbles and homogeneous
• No permanent resistance to UV light (yellowing does occur), it therefore should be protected, where appropriate, against UV radiation with an additional coating (clear coat or opaque paint)

This colourless, non-drip formulated gelcoat can be dyed opaque with our Universal Colour Pastes and transparent/translucent with our Transparent Colours.

Technical notes:

*New, optimized formula for EP gelcoat

The colourless EP gelcoat NOVA is based on a new formula that has been optimized with preventive health protection in mind. By eliminating potentially harmful reactive thinners, handling is safer for the processor. At the same time, the mechanical properties of the resin are improved—especially hardness and heat resistance.

Mono- and difunctional reactive thinners are commonly used to reduce the viscosity of epoxy resins. However, they also reduce the concentration of reactive epoxy groups, which leads to a lower cross-link density in the cured material. A reduced cross-link density makes the material less rigid and resistant – the hardness decreases.

Heat resistance, especially the glass transition temperature (Tg), is also directly dependent on the crosslink density. Reactive diluents can significantly lower the Tg because they make the polymer network less rigid. The absence of these additives in EP Gelcoat colourless NOVA therefore results in higher material hardness and significantly improves temperature resistance

Storage/shelf life:

In unopened containers at 20-25 °C 12 months.
