Epoxy gelcoat VI 5090

for marine applications

The VI 5090 is a high resistance Gelcoat formulated on a Vinylester resin base. Its main characteristics are a very high resistance to solvents and chemical agents, which makes it an excellent product for tooling, but also its high TG of 105 degrees makes it a product of choice for Pre-preg parts For tooling, the VI 5090 enables the mould to have a permanent high gloss aspect resisting to many cycles between waxing/polishing. Thanks to its low dilatation module when exposed to temperature and its flexibility, the VI 5090 is not prone to cracks and the appearance of mat zones. The VI 5090 comes in a Neutral (transparent) Color but can be delivered in any RAL color or with RAL pigments. APPLICATION Application with spray gun or brush are both possible. In order to spray the VI 5090, it is possible to dilute it with styrene up to 5% and Acetone up to 3%. To avoid any risks of porosity, we recommend to catalyze the VI5090 with Resoltech MEKP (2 to 2,5%). As always when using a product in a new application, it is always recommended to test the system on a small surface of the same characteristics of the main surface to be sprayed or painted with rollers or brushes. 100% epoxy compatible Application by brush, roller or spray gun For tooling and parts Wet lay-up, infusion or pre-preg TG (°C) 105 Mix density 1.1 Mix viscosity (mPa.s) 9,000 - 20,000 Gel time on 70 mL, 4cm at 23°C 10m - 45m
