Q1: What types of waterborne epoxy resins is YPWEC-0380 compatible with?
A: YPWEC-0380 is formulated for compatibility with common anionic and non-ionic waterborne epoxy dispersions, including those based on diglycidyl ether of bisphenol A (DGEBA) and modified aliphatic epoxies. Compatibility should be verified through lab-scale formulation trials under intended pH and shear conditions.
Q2: How does YPWEC-0380 affect pot life and film formation in waterborne epoxy coatings?
A: It offers extended working time compared to highly reactive amine-based curing agents, supporting stable dispersion during application. Film formation proceeds via coalescence and crosslinking at ambient or mildly elevated temperatures, yielding cohesive, low-VOC films with good early water resistance.
Q3: Can YPWEC-0380 be used in food-contact or industrial maintenance coatings?
A: YPWEC-0380 is suitable for industrial maintenance and protective coating applications where low VOC and water-based processing are required. For food-contact use, final formulation compliance must be assessed by the formulator against applicable regulatory frameworks, as the agent itself is not pre-certified for such applications.
Q4: What is the recommended dosage range for optimal cure performance?
A: Dosage depends on the epoxy equivalent weight (EEW) of the resin and desired performance profile, but YPWEC-0380 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to total solids—and adjusted based on cure speed, hardness development, and chemical resistance requirements.
