{"product_id":"rubber-guard-ns-butyl-rubber-sealant","title":"Everkem Rubber Guard NS Butyl Rubber Sealant","description":"\u003cp\u003eThe Rubber Guard NS Non-Skinning Butyl Rubber Sealant from \u003ca href=\"\/companies\/everkem\"\u003eEverkem Diversified Products\u003c\/a\u003e comes in a 10.1 oz cartridge and delivers a durable, waterproof bond that stays permanently flexible. This grey butyl sealant meets \u003ca href=\"\/resources\/building-codes-standards\/astm-envelope\"\u003eASTM-C919 standards\u003c\/a\u003e and maintains low VOC content at 100 g\/L, making it suitable for interior and exterior sealing applications.\u003c\/p\u003e\n\n\u003cp\u003eThe non-skinning formula adheres to most building materials without forming a surface skin, which makes it ideal for applications where you need ongoing flexibility. You can use this sealant in STC-rated assemblies as an acoustical sealant, helping with sound dampening in wall and ceiling systems. The EcoSeal formulation keeps environmental impact low while delivering the performance you need on the jobsite.\u003c\/p\u003e\n\n\u003cp\u003eThis butyl sealant works well for sealing gaps in concrete, masonry, metal, and wood surfaces where movement is expected. The permanently flexible nature means it won't crack or lose adhesion when building materials expand and contract with temperature changes. Made in the USA, it's ready to use straight from the cartridge with standard caulk guns.\u003c\/p\u003e\n\n\u003c!-- everkem-tech v1 start --\u003e\n\u003csection class=\"us-tech-block\" data-vendor=\"everkem\"\u003e\n\u003cstyle\u003e\n.us-tech-block { margin-top: 1.5rem;
