A. Silicon Diol-based Polydimethylsiloxane 100 Methyltrimethoxysilane 5
3-aminopropyltrimethoxysilane 15 dibutyltin dilaurate 0.5
B. Upper A polymer 100 dry silica (surface treated with dimethyl dichlorosilane [Si(CH3)2Cl2]) 5
Preparation Two components of A were mixed and stirred at 100°C for 6 hours to remove methanol and excess monomer to give an amino-containing methoxysilyl-containing polydimethylsiloxane oil. The polymer was combined with the other components B. After the B components were mixed, they were coated on the object and allowed to cure for 7 days at room temperature without sticking for 2 hours.
Use The glue is used for the bonding of metal such as iron and aluminum.
