3:1 Super Long Pot Life Epoxy Resin for Surfboard
Model: 318AB-RTM Mixing Ratio: 3:1 by weight
318AB-RTM is a 3:1 surfboard laminating epoxy resin for fiberglass reinforcement, board layers and coating work that needs controlled wetting. Its blue transparent Part A and clear Part B blend into a workable system with balanced viscosity for fabric coverage. The 40-minute pot life suits planned laminating steps, while full curing in about 12 hours helps improve production rhythm. After curing, the resin reaches Shore D 90 hardness for firm surface performance. This formula fits surfboard structures that need fabric penetration, clear coating behavior and stable cured strength.
