Epoxy Chemistry
Understanding the chemistry behind epoxy resin is vital for achieving the best results in your projects. The process begins when the epoxy resin and hardener are mixed together, initiating a chemical reaction (WEST SYSTEM). This reaction causes the liquid ingredients to transition through several stages:
-
Liquid Phase (Open Time): The initial stage when the resin is fully mixed and remains in its liquid form. This phase offers an opportunity to apply the epoxy to the desired surface.
-
Gel Phase (Initial Cure): During this stage, the epoxy starts to thicken and becomes tacky. Although it’s not fully cured, it begins to set and becomes less workable.
-
Solid Phase (Final Cure): In this final stage, the epoxy transforms into a solid state, completing the curing process. The material is now rigid, tough, and ready for use.
The entire curing process of epoxy resin, also known as cure time, is crucial for ensuring a strong bond and long-lasting durability.
