UV Stable Clear Epoxy Resin for Casting Applications

Mixing by Volume - Resin 2 : 1 Hardener

Mixing is critical and must be accurate. 2 parts resin for 1 part of hardener will provide a hard and rigid casting once cured. Pour the hardener first then the resin. The combined liquids must be thoroughly mixed manually or mechanically to completely remove any haziness or streaks, scraping the sides and base of the mixing pot then transferring the mix to a second container and stirring is best practice for good castings. An entirely homogeneous mix is essential in achieving optimal results. It is important to only mix the correct quantity at a time as epoxy systems tend to exotherm when kept in a mass.

(Mixing by weight: 100g resin to 45g hardener pro-rata).

Application Guidelines

The mixture can then be poured into a mould. The mould can be a hard mould or made of silicone rubber. Moulding can be carried out by gravity or under vacuum or pressure.

It does not trap air easily and does not heat up when used properly. Temperature should be between 18 to 25ºC. Humidity level below 70%. Pot life for a 500g mix at 22ºC is approx 8-10 hours.

The mix will produce a hard casting, suitable for manufacture of fancy shapes, decorative items etc. Should a new mix be applied onto cured resin, the contact surface should always be sanded in order to enhance adhesion.


This resin will cure at different rates based on the volumes used and thickness of parts.

Typically a 500g, 10cm thick cast will be de-mouldable after 24 hours @ 25°C. The resin will continue to cure for several days at room temperature.

Thin section castings can be made to cure faster by post-curing. This involves initial curing at room temperature for 24 hours, then increasing the temperature (up to 60°C max.) for 15 hours.
