Q1: What is the primary chemical composition of WANHUA WANNATE PM 200?
A: WANHUA WANNATE PM 200 is a polymeric diphenylmethane diisocyanate (pMDI)-based curing agent, formulated to provide consistent reactivity and excellent crosslinking performance in two-component polyurethane systems.
Q2: How should WANHUA WANNATE PM 200 be stored to maintain stability and performance?
A: Store in tightly sealed containers under dry, cool conditions (below 30 °C), away from moisture, direct sunlight, and incompatible materials such as amines or alcohols. Prolonged exposure to humidity may cause gelation or viscosity increase due to premature reaction with water.
Q3: What types of resins or base components is WANHUA WANNATE PM 200 typically compatible with?
A: It is widely used with hydroxyl-terminated polyesters, polyethers, acrylics, and polyester-polyol blends in coatings, adhesives, sealants, and elastomers. Compatibility and pot life depend on the molecular weight and functionality of the polyol component.
Q4: What safety precautions are essential when handling this isocyanate curing agent?
A: As with all isocyanates, avoid inhalation of vapors or aerosols and prevent skin and eye contact. Use appropriate engineering controls (e.g., local exhaust ventilation) and personal protective equipment (chemical-resistant gloves, goggles, and respiratory protection where required). Always consult the Safety Data Sheet (SDS) before use.
