It is engineered for contractors performing perimeter weathersealing, field glazing, window and door installations, and primary backbedding applications. The product cures in the presence of moisture to deliver excellent resistance to cold, rain, ozone, heat, and sunlight. Its primerless adhesion to a wide range of substrates — including vinyl, wood, aluminum, brick, concrete, fiber cement, and metal roofing — makes it a versatile choice for building envelope work.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCure Type\u003c\/td\u003e\n\u003ctd\u003e100% Neutral Cure (one-part, moisture-curing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrade\u003c\/td\u003e\n\u003ctd\u003ePremium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContainer Size\u003c\/td\u003e\n\u003ctd\u003e10.1 fl oz cartridge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexibility\u003c\/td\u003e\n\u003ctd\u003ePermanently flexible; stays fully elastic after curing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUV Resistance\u003c\/td\u003e\n\u003ctd\u003eUV resistant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOdor\u003c\/td\u003e\n\u003ctd\u003eLow odor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVOC Content\u003c\/td\u003e\n\u003ctd\u003e26 g\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eVarious\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModulus\u003c\/td\u003e\n\u003ctd\u003eMedium modulus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMovement Accommodation\u003c\/td\u003e\n\u003ctd\u003e+\/- 50%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecific Gravity\u003c\/td\u003e\n\u003ctd\u003e1.18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSag \/ Slump\u003c\/td\u003e\n\u003ctd\u003eNIL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTack-Free Time\u003c\/td\u003e\n\u003ctd\u003e20 min.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCure Time (75°F, 50% RH, 3\/8\" thick)\u003c\/td\u003e\n\u003ctd\u003e24 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtrusion Rate\u003c\/td\u003e\n\u003ctd\u003e250 g\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElongation (cured)\u003c\/td\u003e\n\u003ctd\u003e500%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDurometer Hardness, Shore A (cured)\u003c\/td\u003e\n\u003ctd\u003e27 +\/- 5 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTensile Strength (cured)\u003c\/td\u003e\n\u003ctd\u003e260 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eService Temperature Range\u003c\/td\u003e\n\u003ctd\u003e-40°F to 325°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication Temperature Range\u003c\/td\u003e\n\u003ctd\u003e-35°F to 140°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Joint Width\u003c\/td\u003e\n\u003ctd\u003e1\/4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Joint Width\u003c\/td\u003e\n\u003ctd\u003e1 3\/16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Joint Depth\u003c\/td\u003e\n\u003ctd\u003e1\/5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Joint Ratio\u003c\/td\u003e\n\u003ctd\u003eWidth = 2 x Depth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication Method\u003c\/td\u003e\n\u003ctd\u003eManual or pneumatic caulking gun\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTooling \/ Finish\u003c\/td\u003e\n\u003ctd\u003eSoapy water before skinning\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClean Up\u003c\/td\u003e\n\u003ctd\u003eWhite mineral spirit immediately after use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRepair With\u003c\/td\u003e\n\u003ctd\u003eSoudasil 400N1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShelf Life\u003c\/td\u003e\n\u003ctd\u003e12 months in unopened packaging; store at 41°F–77°F in cool, dry conditions.
