Technical Data Sheet - 01/28/2009 RESOLCOAT 7080 GC Hardener 7086 GC Epoxy Gelcoat for Tooling Application and demoulding at room temperature High modulus & mechanical properties TG > 90°C RESOLCOAT 7080GC epoxy gelcoat is formulated for the production of composites tooling. It enables to manufacture tooling with no contraction and its Novolac based formula guarantees the highest mechanical and chemical resistance, notably to Styrene. Polyester or Vinyl ester parts manufactured on the 7080GC gelcoat will release with high gloss for numerous cycles. If needed to be repaired, polishing the repaired area will enable to regain a high gloss surface aspect. This new generation system, optimized with excellent self levelling characteristics and excellent air release, is suitable for the manufacture of large composite tooling. It can be applied by brush roller or airless while guaranteeing low toxicity working conditions to the users. The recommended application thickness ranges from 500 m to 900 m @ 25°C, which it is possible to achieve in one coat on a vertical surface without sag. Laminates can be released from the moulds after room temperature curing. The minimum time before demoulding will depend on the cure schedule of the associated laminate. Final thermo-mechanical properties will be obtained after a post curing cycle defined according later in this technical data sheet.

Gelcoat 7080 GC Hardener 7086 GC Tooling Epoxy Gelcoat MIXING RATIO Resin 7080 GC Hardener 7086 GC 100 pbw 30 pbw Warning: the mixing ratio must be accurately followed. It is not possible to change the ratio, it would result in lower mechanical properties. The mixture should be thoroughly stirred to ensure full homogeneity. It is important to note that epoxy systems tend to heat up much faster in a pot than as a thin film. It is preferable to only mix the necessary amount usable within the given pot life. Keeping the mixture in flat open containers reduces the risks of exothermic reaction....

Gelcoat 7080 GC Hardener 7086 GC REACTIVITY @ 23°C Reactivity measures on Trombotech according to ISO 2535 Norm Gel time on 100g 60 min Temperature at exothermic peak on 100g ND 4h Touch Dry on 1 mm layer CURE & POST CURING The 7080GC system will cure at room temperature enabling to release parts from the moulds at room temperature after 24h. A further post-cure of 15h at 60 °C will enable the gelcoat to obtain 100% of it´s mechanical characteristics. Touch dry on 900 m : Hard & sandable : Releasable from mould: Full cure : 4 Hours @ 25 ºC 12 Hours @ 25 ºC 24h at room temperature 7 days at...
