Q1: What is the primary function of ERA POLYMER CC60D TDI Curing Agent in polyurethane systems?
A: CC60D is a TDI-based aromatic curing agent designed to react with hydroxyl-terminated prepolymers or resins, enabling rapid crosslinking and development of high mechanical strength, abrasion resistance, and thermal stability in final polyurethane elastomers and coatings.
Q2: Is CC60D compatible with aliphatic polyol systems, or is it limited to aromatic formulations?
A: While CC60D is optimized for use with aromatic polyols and prepolymers—where its reactivity and performance profile are fully leveraged—it can be incorporated into certain hybrid or semi-aliphatic systems. However, compatibility and cure kinetics should be verified experimentally, as reduced reactivity and potential phase separation may occur with highly aliphatic components.
Q3: How does CC60D compare to MDI-based curing agents in terms of pot life and cure speed?
A: Due to its TDI backbone, CC60D generally offers faster initial reactivity and shorter pot life compared to most MDI-based alternatives, making it suitable for applications requiring rapid demolding or high-throughput casting. Final cure development remains robust, though ambient moisture sensitivity is higher and handling precautions are recommended.
Q4: What storage conditions are recommended to maintain product stability?
A: Store CC60D in tightly sealed containers under dry, inert atmosphere (e.g., nitrogen blanket), at temperatures between 15–25°C. Avoid exposure to moisture, heat above 40°C, and direct sunlight. Prolonged storage or improper sealing may lead to dimerization or surface skinning due to its inherent TDI reactivity.
Q5: Can CC60D be used in solvent-free or low-VOC formulations?
A: Yes—CC60D is a liquid, low-viscosity curing agent that can be formulated without solvents. It is commonly employed in 100% solids polyurethane systems; however, VOC content of the final formulation depends on the full system composition, including any residual monomer or co-reactants.
