MGS RIM H937 Hardener (Drum/net 190 Kg)

EPIKURE Curing Agent MGS RIMH 937, designed for use with EPIKOTE™ Resin MGS RIMR 935, is a highly efficient curing agent tailored for advanced composite applications. Based on a blend of aliphatic and cycloaliphatic amines, RIMH 937 delivers excellent mechanical performance, extended pot life, and high thermal stability.

Application:

• Boatbuilding
• Automotive parts
• Tooling
• High-performance structural components

Mixing and Preparation

• Mixing Ratio:
  By weight: 100 (RIMR 935) : 38 ± 2 (RIMH 937)
  By volume: 100 (RIMR 935) : 45 ± 2 (RIMH 937)

Application Techniques

RIM (Resin Infusion Molding)

• Description: Resin is infused into dry reinforcements under vacuum pressure, ensuring even saturation and eliminating air pockets to produce strong, uniform composites.
• Best For: Creating complex shapes, minimizing waste, and producing lightweight, durable structure.

Hand Layup

• Description: Resin is applied manually to the reinforcement materials with tools like brushes or rollers.
• Best For: Prototyping and small-scale projects.

Processing Temperature

• Recommended Processing Temperature Range: 20 - 25 °C (68 - 77 °F). Higher temperatures are possible but reduce pot life.

Curing Process

• Initial Curing: Parts require heat treatment at a minimum temperature of 50 °C (122 °F) after initial room-temperature curing to achieve full mechanical properties.
• Curing Agent Compatibility: Compatible with RIMR 935 resin.
• Post-Curing:
• At 80 °C (176 °F): TG = 90 - 100 °C (194 - 212 °F)
• At 100 °C (212 °F): TG = 105 - 120 °C (221 - 248 °F)
• At 140 °C (284 °F): TG = 135 - 150 °C (275 - 302 °F)
