Surface Casting Resin for Foundry Applications
URECAST-FND is a Polyurethane Resin system specially developed for foundry Casting applications.This thermoset resin system is recommended for foundry tools(Patterns and Core boxes) on CNC metal performs.
The Resin and Hardner mix system cures at room temperature and gives a solid block of Shore D 65-70 with excellent abrasion resistance , flexibility and tenacity.
Properties
- Excellent Abrasion Resistance
- Very Good impact and shock resistance
- MDA free Non-Toxic system
- Room temperature quick hardening

Processing Conditions
- Container of Urecast-FND should be stirred well before use
- Weigh Resin part and Hardner part in the recommended ratio and mix homogenously for atleast 4 to 5 minutes with mechanical stirrer or manually
- Applying vacuum to the mix system will give better results.The pouring of the system should be finished within 15 minutes after the mixing
Storage
- Store in a cool and dry conditions with caps properly tightened .
- Packing:
- Resin - 30 kg. Pail
- Hardner - 5 kg. can
