Application of Composite Silane Coupling Agent LY-178 in Silane Modified Polyether Sealant
Multiple silane coupling agents are selected for comparison and compounding,and their effects on the curing speed,mechanical properties and bonding performance of sealant are analyzed.The results indicate that KH-792 has improved curing speed and tensile strength due to its diamino-structure,while LY-178 exhibits excellent comprehensive performance.The use of LY-178 and KH-792 compound as a silane coupling agent can significantly enhance the bonding performance of the sealant to various substrates without affecting its mechanical properties.
