METHOD FOR SEALING COMPONENT EXPOSED TO AGGRESSIVE WORKING SOLUTION AND ROOM TEMPERATURE VULCANIZABLE-1 SILICONE COMPOSITION ADEQUATE FOR USE THEREFOR

摘要

PURPOSE: A method for sealing component exposed to aggressive working solution and room temperature vulcanizable silicone composition, which is applicable to cast, injection-type casket, sealant, other caskets and any conventional field, are provided. CONSTITUTION: In the method for sealing the component with room temperature vulcanizable -1 silicone sealant, an aggressive working solution-resistant sealant is chosen as the sealant, wherein the sealant is prepared by hardening a sealant which comprises: a) 10-90 wt.% of organopolysiloxane composition comprised of at least one silanol-working organosiloxane; (ii) an effective amount of an amino-working cross linking agent for hardening the sealant composition in the presence of water; (iii) 5-50 wt.% of iron oxide; and (iv) 2-50 wt.% of magnesium oxide.
