Collect performance requirements from customers or the market, Define R&D objectives.

Select suitable basic raw materials and evaluate their compatibility and reaction characteristics with epoxy resin.

Based on the target performance, different formulation ratios, and mixing conditions (temperature, pH, reaction time) are set.

Samples were prepared on a laboratory scale, and curing speed, mixing viscosity, pot life, surface drying time, and mechanical properties were tested.

The samples were tested in combination with the target epoxy system to evaluate adhesion, water resistance, chemical resistance, and gloss retention.
