TECHSIL IS803 is a ready to use, one part room temperature vulcanising (RTV) elastomer, which cures on exposure to moist air to give a permanently elastic rubber. TECHSIL IS803 has excellent temperature resistance in its cured state. It is recommended for industrial applications where a high modulus sealant with good adhesive properties is required.
