BLOCKED POLY-ISOCYANATE
PRODUCT OVERVIEW
HYDROSIN® fluorine-free blocked-isocyanate. They can be used as crosslinking agents for various coating applications that require heat-curing cycles. Applications include increased durable water repellent (DWR) effect and soil release properties. The durability and the adhesion of coatings are also improved. All of our HYDROSIN® blocked-isocyanate polymers are formaldehyde-free.
PROPERTIES
- IMPROVE THE DURABLE WATER REPELLENCE (DWR) EFFECT
- IMPROVE THE SOIL RELEASE PROPERTIES ON TEXTILES AND LEATHER
- IMPROVE THE RESISTANCE TO CHEMICAL AND TO ENVIRONMENTAL ATTACK
- ENHANCE THE LAMINATION AND ADHESION OF COATINGS
- IMPROVE THE DURABILITY OF COATINGS AND ADHESIVES IN AQUEOUS-PAD APPLICATIONS
- IMPROVE THE RESISTANCE TO BLOOD AND SALINE PENETRATION IN WOVEN AND NONWOVEN FABRICS
- REQUIRE HEAT-CURING CYCLES
POLY-CARBODIIMIDE
PRODUCT OVERVIEW
HYDROSIN® fluorine-free carbodiimide crosslinkers. They are an excellent alternative for more hazardous isocyanate and aziridine crosslinkers. They react with COOH groups (in acrylic and polyurethane polymers) forming the so-called “interpenetrating network” with the polymeric binder. The result is a dense network that improves the resistance performances of the coating against cleaning liquids and prevents sun cream lotions, food and chemicals stains.
PROPERTIES
- INCREASE STRENGTH AND HARDNESS
- IMPROVE ABRASION AND CHEMICAL RESISTANCE
- IMPROVE THE RESISTANCE TO HYDROLYSIS
- INCREASE THE ADHESION TO SUBSTRATES
- IMPROVE PRODUCTS POT-LIFE
- NOT MOISTURE SENSITIVE
- FAST CURING SPEED
