1.Optimized physical and chemical properties: It appears as an amber viscous liquid with a slight amine odor, which is easy to identify and use. The viscosity is stable at 3000-3500cPs (40°C), ensuring excellent fluidity and processability, and can be easily mixed with various polyurethane raw materials. The water content is less than 500ppm, which effectively avoids adverse effects on the curing reaction and product performance, ensuring the stability of the formula system.
2. Precise amino equivalent: The amino equivalent is controlled at 575-625, which provides accurate reaction ratio for polyurethane curing, ensures sufficient crosslinking degree of the system, and effectively improves the mechanical properties and durability of the finished product. The high reactivity of amino groups enables rapid curing under appropriate conditions, improving production efficiency.
3. Easy operation and wide adaptability: It is extremely easy to operate and can be directly used in various processing processes without complex pretreatment. It is especially suitable for on-site repair scenarios, which can greatly reduce the difficulty of on-site construction and improve construction efficiency. It is compatible with various polyurethane raw materials and has strong versatility.
4. Excellent curing performance: When used as a curing agent for MDI, it can realize direct one-step curing. The physical properties of the obtained products are generally similar to those of traditional thermal curing systems using MDI prepolymers, and at the same time, its performance is superior to those MDI/glycol thermal curing elastomer systems. It effectively solves the defects of traditional curing systems such as complicated process and insufficient performance.
5. Low shrinkage rate: The elastomer based on Amine-HCA™ P-1000 has extremely low shrinkage rate when operated in natural environment, which can effectively avoid product deformation, cracking and other problems caused by shrinkage during curing, ensuring the dimensional stability and appearance quality of the finished product.
