Bio-Based Resin 305 - High-Temperature Compression Moulding Processes

Entropy Resins' 305 Epoxy Resin

Entropy Resins' 305 epoxy resin is designed for rapid compression molding, optimizing heat-based processes for fibre-reinforced composites.

The resin features excellent fibre penetration and thixotropic characteristics to limit sagging in high-temperature curing applications.

Thanks to its high modulus, 305 resin has excellent elongation properties, enabling durable, lightweight composite parts.

Epoxy 305 is a USDA BioPreferred product with a 28% biobase content.

Available Hardeners

• CPS (Slow): Working time: 50 minutes at 25°C and offers complete polymerization in 20 minutes at 82°C. Perfect for applications where great flexibility is required.
• CPF (Fast): Working time 20 minutes at 25°C and allows complete polymerization in 15 minutes at 82°C. Ideal for projects requiring fast cycles.

Applications

• Snowboards
• Skateboards
• Skis
• Press molding composites...

Key Benefits

• Environmentally friendly: Developed with Super Sap technology from renewable raw materials derived from co-products or waste from other industrial processes, Entropy Resins' 305 epoxy resin contains 28% biobased components, and is certified by the USDA Certified BioBased Product label.
• Low viscosity: Facilitates fibre wetting and reduces sagging. Ensures even application.
• Thermal and mechanical resistance: Excellent stability at high temperatures and resistance to mechanical stress.

Mechanical Strength

Consumption: approx. 3 litres for 2 snowboards or 2 pairs of skis.

Directions for Use

• For best results, make the mixing ratio of the two components based on the weights indicated.
• Mix thoroughly for at least 2 minutes, scraping all surfaces of the container to ensure even mixing.
• Work in a temperature-controlled environment to respect the product's optimum limits. Avoid using the product in environments with cold ambient temperatures or high humidity.
• For optimum curing performance, make sure surfaces are dry and free of dirt, debris and oil. Surface preparation by sanding is strongly recommended.
• Carry out preliminary tests with the materials and processes envisaged to fully understand the curing characteristics of epoxy in your working environment with the materials.

Note

During polymerization, an amine veil may form, with a sticky, waxy or oily appearance. This can reduce adhesion and make sanding more difficult. To remove it, you can use WEST SYSTEM's cleaner.
