Why Choose KSTO Anti-hydrolysis Additives ?
Carbodiimide anti-hydrolysis agents can provide excellent hydrolysis resistance protection for polymers containing ester, urethane and amide groups, maintain the initial mechanical properties of products, prolong the service life of products, and make your polymer products widely used in harsh environments such as high temperature and humidity.
Compared with the traditional thiourea process, our company takes the lead in using isocyanate condensation process to produce carbodiimide hydrolysis resistant products, which have the characteristics of high purity, high activity, no smell, no discoloration and no sulfur residue.
KSTO has been committed to providing our customers with high-quality, cost-effective carbodiimide anti-hydrolysis additives.
Product Feature
☆ Liquid type, easy to operate, easy to add, good compatibility with materials；
☆ Moderate activity, high-efficiency acid value reduction ability and good migration resistance;
☆ It can significantly improve the hydrolysis resistance of materials containing ester groups and prolong the service life of materials;
☆It has good safety and can be used in materials in contact with food.
Application
This product has four major advantages: resistance to hydrolysis, enhanced crosslinking, thermal stability and weather resistance. It can significantly inhibit the hydrolysis embrittlement, strength attenuation and discoloration of polycondensation materials such as PET, PBT, TPU, PA, TPEE and PLA under extremely harsh environments like damp heat, acid and alkali, and outdoors. Low addition amount, high efficiency, no impact on the transparency, hand feel and processing fluidity of the base material, can simultaneously enhance adhesion, scratch resistance, solvent resistance and durability, and extend the service life of the product by several times. The product features stable storage, wide compatibility, and good compatibility with water-based/solvent-based systems. It does not precipitate or agglomerate, meeting the long-term reliability requirements of high-end electronics, automobiles, textiles, films, and degradable materials.
The application fields cover numerous scenarios such as engineering plastic modification, polyurethane elastomers, adhesives, coatings and inks, synthetic leather, cable sheaths, photovoltaic back sheets, filters, and degradable packaging. Improve the wet heat stability in engineering plastics such as PET, PBT and PA; Long-lasting hydrolysis resistance in TPU, CPU and polyester polyol systems; It is used as a low-temperature crosslinking agent in water-based coatings, acrylic emulsions and polyurethane dispersions to enhance water resistance and chemical resistance. In biodegradable materials such as PLA and PBAT, premature hydrolysis is inhibited, taking into account both the usage intensity and the controllable degradation rhythm.
This product, with its stable structure, highly efficient activity and broad-spectrum compatibility, has become a key additive for the anti-hydrolysis modification and environmentally friendly cross-linking upgrade of materials, helping customers achieve high-performance, long-life, low-cost and green compliance integrated material solutions.
