MODIFIED SILICONE-BASED SEALANT COMPOSITION EXCELLENT IN THIXOTROPY

摘要

PROBLEM TO BE SOLVED: To obtain a modified silicone-based sealant composition added with excellent thixotropy and presenting no dropping without using any swelling process. SOLUTION: This sealant composition is obtained by using a modified silicone polymer as a main component and compounding a polybutene having 300-4000 molecular weight together with calcium carbonate treated with a fatty acid.
