Epoxy Resin Gelcoat

The CTech-LLC^®  EPG™ is an epoxy resin gelcoat for use as a surface coat when making frp based composite parts and gfrp lining of structures.
The CTech-LLC^®  EPG™ epoxy gelcoat works as the external coat of one of the surfaces of the laminate, providing protection against chemicals, weathering, humidity or any aggression from the environment.

Key Features

• Color quality and stability
• High chemical resistance
• Excellent resistance to a multitude of chemicals
• Heat resistance
• Resistance to abrasion and corrosion
• Resistance to the action of UV radiation and temperature changes
• Can be used where drinking water approval is needed
• Hardly present volumetric shrinkage

Applications

• The manufacturing of reinforced parts and moulds/tools with thermosetting epoxy resins.
• Gelcoat for GFRP lining of storage tanks, pipelines etc.

Storage Conditions

• EPG™ epoxy gel coat and hardener should be kept in tightly sealed containers during transport and storage. Both the gelcoat and hardener should be stored in ambient conditions of between 4°C and 40°C.
• When stored correctly, the resin and hardener will have a shelf-life of 18 months..

Shelf Life

• When stored correctly, the resin and hardener will have a shelf-life of 18 months.
