Epoxy Resin measuring Tip

For best results weigh out the required amount of resin, divide this by 100, then multiply by the Hardener ratio found on Hardener container (weight) to give you Hardener quantity. Then mix well. Always use the correct Hardener for Epoxy Resin as most of the Hardeners are not interchangeable unlike Polyester Resin.

Finishing Epoxy resin

This resin is very low viscosity, which makes an ideal resin for use with lightweight glass cloth on model aircraft wings and fuselage. With its long pot life of 45 minutes, this gives you plenty of working time. The resin curing process should be left at temperature 20°C or above for 24-36 hours.

Usually 2 coats are applied, one to wet out the glass cloth and another to fill the weave of the glass fibre cloth. This produces a smooth, tough and highly durable surface. This surface will accept all paints such as high build filler primer, Humbrol enamels, cellulose, acrylic, and two pack synthetics.
