Products in Transportation Assembly: Silicones

Evonik Crosslinker 100, part of the Crosslinker 100 series, consists of polydimethylsiloxanes containing SiH groups within the polymer chain. In addition to SiH groups within the chain, the Crosslinker 100 series features terminal SiH groups. These crosslinkers are essential components of polyaddition silicones. When working with two-component silicone formulations, it is crucial to maintain strict separation between Pt catalysts (e.g., Catalyst 500 series) and SiH crosslinkers to ensure proper performance.

CoatOSil™ 7001E silicone-polyether block copolymer can enhance the appearance of solvent-borne coatings, especially two-component acrylic-polyol isocyanate cured coatings. The addition of CoatOSil™ 7001E copolymer can improve the final cured coating’s distinctness of image (DOI), film clarity and film coalescence, and can also readily accommodate recoating.

TSR1452 silicone forms a medium-hard film that helps provide excellent thermal resistance and good gloss and color retention in paints with 60% solids content. As a low molecular weight polymer, it can  aid in good compatibility with a wide range of organics.

Silquest™ A-1106 silane is an aqueous solution of an aminoalkyl siloxane. This alcohol-free siloxane improves signifi- cantly the adhesion and coupling between organic resins and inorganic surfaces. Momentive Performance Materials Silquest™ A-1106 silane is most often used in aqueous systems where the alcohol of hydrolysis causes instability of the formulation or where a high flash point additive is required. The product also reduces volatile organic content (VOC) and does not contain hazardous air polluting substances (HAPS). These benefits are particularly useful to manufacturers seeking to reduce emissions from their water-borne products and processes.

CoatOSil™ 7510 coatings additive is a silicone copolymer with a pendant structure and polypropylene oxide (PO) side chains. The all PO side chain helps minimize the potential for foam stabilization, making CoatOSil™ 7510 coatings additive an excellent candidate as a defoamer in water-borne industrial or decorative coating formulations.

CoatOSil™ 7600 coatings additive is a silicone polyether copolymer with a pendant structure. It has been incorporated as a wetting agent or co-emulsifier in industrial and decorative water-based coatings.
