Model<\/strong>\u00a0strong> PU-655<\/h4>\n

Type<\/strong>\u00a0strong> Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI)<\/h4>\n

Used as a water-based two-component Curing agent component of polyurethane system<\/h4>\n

Introduction<\/strong>\u00a0strong><\/h4>\n

PU-655 is a Crosslinker for aqueous systems; such aqueous systems need to be characterized by good bond stability and chemical resistance.<\/h4>\n

<\/h4>\n

Usage<\/strong>\u00a0strong><\/h4>\n

Because of moderate hydrophilicity The balance between high performance and high functionality, waterborne two-component polyurethane coatings prepared with PU-655 have the characteristics of fast drying and fast curing, and the formed film has high final hardness and excellent chemical resistance. . PU-655 can also be used as a cross-linking aid for water-based polyols and as a cross-linking agent for most neutral water-based polymer dispersions such as polyurethane, polyvinyl acetate, polyacrylate and synthetic rubber dispersions.<\/h4>\n

Stored in secretIn a sealed container<\/h4>\n

Recommended storage temperature: 0- 30 \u00b0C.<\/h4>\n

Resists 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. It must therefore be stored in airtight containers. Water in various forms (humid air, solvents, wet containers)<\/h4>\n

must be blocked because CO2 The generation of will lead to the increase of pressure and cause danger. High temperature storage will cause a slight increase in viscosity and color.<\/h4>\n
