Momentive Performance Materials, a global leader in specialty chemicals and materials, has expanded its portfolio of high performance hardcoat systems with the introduction of the AS4700/SHP470 FT2050 weatherable silicone hardcoat and the PHC587C primerless thermal hardcoat.
The AS4700 system is a state-of-the-art, ultraweatherable thermal hardcoat for black and tinted polycarbonate. It offers advanced weathering performance combined with high abrasion performance and superior chemical resistance. The system’s patented ultraviolet (UV) radiation absorber technology offers excellent photo stability, and its strongly networked siloxane resin provides high abrasion resistance. The AS4700 system has been approved by leading global original equipment manufacturers and Tier 1 suppliers for use in protecting exterior black and transparent automotive parts. It is also an excellent candidate to consider for architectural glazing.
PHC587C is the latest generation of a primerless thermal hardcoat, offering improved performance and processing features, including a unique adhesion promoter technology incorporated into the siloxane resin matrix and Momentive-patented UV absorber technology. This can enable superior outdoor performance and primerless adhesion. The new hardcoat has been approved by the Economic Commission of Europe (ECE) and Automotive Manufacturers Equipment Compliance Agency (AMECA) for use in automotive headlamps. It is also an excellent candidate to consider for other applications with molded and extruded parts.
“These innovations can enable the increased use of polymeric materials in more demanding exterior applications, which, in turn, can allow for greater weight reduction and more styling options,” said Sandip Tyagi, Global Marketing Director - Coatings, Momentive.
