MAS MAS Epoxy Low Viscosity — Mix Ratio & Calculator
Data sourced from manufacturer SDS & TDS · Last verified July 18, 2026
Quick Answer
MAS MAS Epoxy Low Viscosity mix ratio: 2:1 by volume, 2:0.93 by weight
Max pour depth: 0.25" · Full cure: 18h · Ideal temp: 72°F
⚠️ Exothermic Risk — The weight ratio (2:0.93) is NOT 1:1. Resin and hardener have different densities. Using a 1:1 scale ratio will result in incorrect curing. Always mix by weight using the ratio above.
Ultra-low viscosity laminating epoxy designed for superior fiberglass and carbon fiber wet-out. Excellent for vacuum bagging, hand lay-up, and composite repair. Extended working time of 50-60 minutes allows for large laminate projects. Low exotherm formulation suitable for thick laminates. Outstanding clarity for clear coating wood and composite surfaces.
