How to choose the right epoxy resin?
Choosing the right epoxy resin depends on performance requirements. Key factors include impact resistance (toughness), glass transition temperature (Tg), working time, and the environment the epoxy will be exposed to. The best resin is the one formulated for the specific mechanical, thermal, and chemical demands of the application.
What performance means when selecting epoxy
Performance refers to how an epoxy behaves once cured. High-performance epoxies offer greater impact resistance, better adhesion, and improved resistance to wear and chemicals. Softer epoxies may be easier to work with, but they sacrifice strength and durability in demanding environments.

Working time, cure speed, and coating thickness

Base coats vs protective topcoats
In many systems, epoxy serves as a base layer rather than the final surface. Protective topcoats can improve UV stability, abrasion resistance, and chemical protection. Using the correct topcoat extends the lifespan and performance of the epoxy system beyond what epoxy alone can provide.
