Polyisocyanate
T&L produces polyisocyanate hardening agents that can be applied to various industries by improving the adhesion,chemical resistance, and mechanical properties of textiles, paints, coatings, synthetic leather, etc.
Akuacure series are water dispersible aliphatic polyisocyanate used as Cross-linker of Active hydrocarbon functional polymer especially for water borne 2 component system .
- Improve Adhesion to wide range of materials : Woods, Metals, Plastics
- Improve Water and Chemical resistance
- Improve Hardness and Abrasion resistance
- Good Anti-yellowing and Weathering properties
- Improve Hydrolysis resistance
- Improve Heat Resistance
- Easy to mix with various water borne system
