Amine-HCA C3-LF is a high-performance delayed reaction amine chain extender specifically developed for polyurethane systems based on MDI. In conventional amine-based chain extenders, high reactivity often leads to rapid curing, making processing difficult, especially in automated casting and mixing systems. Amine-HCA C3-LF addresses this challenge by providing controlled reaction kinetics, enabling better processability and improved production efficiency.
This product functions both as a chain extender and curing agent in polyurethane formulations, particularly in polyester and polyether systems. It is engineered to provide a balanced reaction profile, allowing sufficient working time while ensuring complete curing and optimal final properties.
Delayed reaction profile for extended processing time
Ideal for automated mixing and casting equipment
Controlled curing behavior for improved process stability
Enhances mechanical properties and consistency
Suitable for both polyester and polyether PU systems
Reduces defects caused by premature curing (bubbles, uneven structure)
Amine-HCA C3-LF is widely used in:
Automated polyurethane casting systems
MDI-based PU elastomers
Industrial molded parts
Rollers, wheels, and structural components
PU systems requiring controlled curing and high precision
As an amine chain extender, Amine-HCA C3-LF reacts with isocyanate groups (–NCO) in MDI systems to form urea linkages. Its delayed reactivity allows better mixing and flow before gelation begins, resulting in improved phase distribution and uniform polymer structure. This leads to enhanced mechanical performance and reduced internal defects.
Used as a curing agent or chain extender in stoichiometric balance with isocyanate
Suitable for automated metering, mixing, and casting equipment
Processing conditions should be optimized based on system formulation
Recommended to control temperature and mixing ratio for best results
Store in a cool, dry, and well-ventilated environment. Avoid exposure to moisture. Keep container tightly sealed. Follow standard industrial safety procedures.
