This red silicone sealant comes in a 10.1 oz cartridge and meets \u003ca href=\"\/resources\/building-codes-standards\/astm-ul-general\/astm-c920\"\u003eASTM C920\u003c\/a\u003e requirements for structural glazing and weathersealing. The sealant maintains flexibility down to -55°F and accommodates +\/- 25% joint movement.\u003c\/p\u003e\n\u003cp\u003eThis NSF-51 certified sealant works in food processing facilities and meets FDA 21 CFR 177 regulations for incidental food contact. The formula resists mold and mildew while maintaining low VOC content at 30 g\/L. Federal specifications TT-S-00230C and TT-S-01453A validate its performance in demanding applications. Made in USA with EcoSeal environmental compliance, this silicone provides 50+ year durability in high-temperature installations.\u003c\/p\u003e\n\u003cp\u003eCommon applications include HVAC ductwork, industrial ovens, boiler connections, and food processing equipment where high heat and sanitary requirements intersect. The sealant works on metal, glass, and masonry substrates in both interior and exterior environments.\u003c\/p\u003e\n\n\u003c!-- everkem-tech v1 start --\u003e\n\u003csection class=\"us-tech-block\"
