\nA-A+
\nModel No. PU-655<\/h4>\n

Type Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI)<\/h4>\n

Curing agent component for aqueous two-component polyurethane systems<\/h4>\n

Description of PU-655<\/h4>\n

PU-655 is a crosslinking agent for aqueous systems, which require good binding stability and chemical resistance.<\/h4>\n

<\/h4>\n

Uses<\/h4>\n

Due to the balance between moderate hydrophilicity and high functionality, waterborne two-component polyurethane coatings prepared with PU-655 are characterized by fast drying and curing, high final hardness, and excellent chemical resistance.PU-655 is also used as a cross-linking additive for aqueous polyols and most neutral aqueous polymer dispersions (e.g., polyurethanes, polyvinyl acetates, polyacrylates, and synthetic polymers). PU-655 can also be used as a crosslinking additive in most neutral aqueous polymer dispersions such as polyurethanes, polyvinyl acetates, polyacrylates and synthetic rubber dispersions.<\/h4>\n

Protection against moisture, heat and foreign substances<\/h4>\n

General information: Hydrophilic isocyanates are very sensitive to moisture and react with water to form<\/h4>\n

carbon dioxide and water-insoluble urea. Therefore, they must be stored in airtight containers. All forms of water (humid air, solvents, wet containers)<\/h4>\n

must be prevented because the production of carbon dioxide can lead to a dangerous increase in pressure. Storage at high temperatures causes a slight increase in viscosity and color.<\/h4>\n
