saturated aliphatic liquid polyol HP 330 Technical Data Sheet:
DESCRIPTION
HP 330 is an odorless, water clear, saturated aliphatic liquid polyol. The saturated nature of the resin provides light- and weather-stability, enabling formulators to develop polyurethane coatings that will not yellow or lose their critical mechanical properties, such as flexibility, adhesion,
elongation, and strength. In addition, HP 330 provides improved heat resistance and adhesion to difficult substrates (i.e., polyolefins)
PRODUCT HIGHLIGHTS
Excellent thermal stability Good weatherability
Hydrophobicity Low color - high clarity
Low glass transition temperature Miscibility with asphalt
Reactive hyroxyl groups
PERFORMANCE PROPERTIES
Acid and Base Resistance Asphalt Miscibility
Electrical Insulative Properties Good Adhesion
Low Temperature Flexibility
SUGGESTED APPLICATIONS
Adhesives, coatings & sealants Electronics, encapsulants
Electronics, potting compounds Polymer modification
Prepolymers - Two-component Thermoplastic polyurethanes (TPU)
Polyurethanes
