The choice of silane coupling agent in silicone adhesive has a significant impact on the performance of the adhesive.

Deacidification type silicone adhesive: Acidic adhesive uses relatively few coupling agents, and now the main one commonly used is D-11 di-tert-butyloxy diacetyloxysilane, which can improve the adhesion of acidic adhesive to metals.

Deoxime type silicone adhesive: The commonly used silane coupling agents for ketone oxime type include LT-550, LT-560, and LT-792. Among them, LT-550 and LT-792 can improve the adhesion and storage stability of the adhesive. LT-792 has better adhesion than LT-550, and in terms of storage stability and yellowing resistance, LT-550 is better than LT-792. LT-560 can improve the curing strength and speed of the adhesive, but excessive addition of coupling agents can affect the storage stability and yellowing resistance of silicone adhesive.

Dealcohol type silicone adhesive: The commonly used silane coupling agents for alcohol type include LT-171, LT-550, LT-560, and LT-792. Among them, LT-550 and LT-792 can improve the adhesive properties and reduce the storage stability of the adhesive, while easily causing yellowing of the adhesive; 171 and 560 can improve the curing speed and storage stability of the adhesive, but the improvement in adhesion is limited.
