Long-chain spacer type silane coupling agents that offers increased hydrophobicity and flexibility

New to the coatings, adhesives, and sealants industries, the KBM-1083 (olefinic functional) and KBM-4803 (epoxy functional) lines have eight carbons – creating more space between the reactive ends of the silanes. Typical silane coupling agents have three carbons separating the organic functional group from the inorganic silicon end. These traditional 3-carbon spacer silanes create a tighter, more rigid network than their 8-carbon counterparts.

The result of this ‘greater space’ presents a significant myriad of benefits that can be formulated into a wide variety of chemistries for Coatings, Adhesives, Sealants, and PSA applications including:

• Increased reactivity due to easier access to the reactive group
• Improved adhesion
• Enhanced flexibility of the cured resin
• Higher filler content enabled
• Greater alkali resistance
• More compatibility with plastics
