Effect of Hydrogenated Silicone Oil on the Performance of Fluorosilicone Sealant
The effects of different types of hydrogenated silicone oil on the mechanical properties,oil resistance and heat re-sistance of fluorosilicone sealants were investigated.The results show that the sealant has good mechanical properties when methyl hydrogenated silicone oil was used as cross-linking agent.The tensile strength and hardness of the sealant has been improved with the increase of active hydrogen,while the elongation at break is vice versa.When hydrogenated fluorosilicone oil is used as cross-linking agent,the sealant has relatively good medium resistance.When phenyl hydrogenated silicone oil is used as cross-linking agent,the fluorosilicone sealant has relatively good heat resistance.
