SC110 1 Gallon Hardener Only

Common situations include running short during large projects, needing to balance leftover resin from previous work, or replacing old or contaminated hardener.

The hardener acts as a curing agent that initiates chemical reactions with the epoxy resin. This polymerization creates cross-linking between molecules, transforming the liquid mixture into a solid thermoset plastic through irreversible chemical bonds.

Incorrect ratios affect the chemical reaction and final properties. Too little hardener prevents complete polymerization, leaving soft spots and poor chemical resistance. Excess hardener can cause brittleness, rapid heat buildup, or surface defects.

While chemically possible, we recommend using our matched resin system for optimal results. Different resin formulations may require different catalyst systems, and mixing brands can affect cure properties, color, or performance characteristics.

The pot life is approximately 45 minutes at 77°F. The chemical reaction accelerates with heat, reducing working time in warmer conditions. Plan your work accordingly and consider environmental factors.

Temperature is the primary factor affecting cure speed. Cooler conditions slow the chemical reaction and extend pot life, while warmth accelerates polymerization. However, extreme temperatures can affect final properties.

Keep in original container with tight seal at room temperature. Avoid temperature extremes and moisture exposure. Properly stored hardener maintains effectiveness for approximately 1 year. Check for crystallization or color changes before use.

Our catalyst system is specifically formulated to balance pot life with complete cure. The chemistry provides predictable heat resistance, optimal cross-linking density, and consistent performance across various applications and environmental conditions.
