Alkoxy type silicone sealants were prepared with various PDMS (polydimethylsiloxane) viscosities. In addition, effect of plasticizer, crosslinkers, and catalyst on sealant performance made by mixture of PDMS viscosities of 20000 and 80000 was investigated. Tensile strength and elongation at break using dumbbell specimens were measured. S-S curve slope was decreased as PDMS viscosity and plasticizer content increased. As PDMS viscosity and plasticizer content increased, elongation at break was increased whereas tensile strength was decreased. As crosslinker content increased, tensile strength was increased and elongation at break was decreased. And, as catalyst content increased, tensile strength and elongation at break were decreased.

Keywords:silicone sealant;alkoxy type;polymer viscosity;crosslinker;plasticizer;catalyst
