Once cured, it forms a flexible, resilient joint with strong adhesion to most common building materials. With an elongation rating of over 600 percent and a Shore A hardness of 25, this sealant accommodates significant joint movement without cracking or pulling away from the substrate. Skin time is approximately 2 hours under standard conditions. It ships in a 10.5 fluid ounce cartridge compatible with a standard caulking gun. Licensed contractors and experienced tradespeople working in construction and building envelope applications are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis sealant is used to create flexible seals on heavy and light precast panel expansion joints. It also performs well on wood, aluminum, and PVC substrates, making it a versatile option for both interior and exterior construction sealing tasks. Typical applications include curtain wall assemblies, precast concrete panels, and general construction joint sealing where long-term flexibility and adhesion are required. It is suited to both residential and commercial construction projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-component formula cures with atmospheric humidity — no mixing required\u003c\/li\u003e\n  \u003cli\u003eElongation of over 600 percent accommodates significant joint movement\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 25 provides a soft, resilient cure\u003c\/li\u003e\n  \u003cli\u003eApproximately 2-hour skin time allows working time for joint tooling\u003c\/li\u003e\n  \u003cli\u003eAdheres to most materials including concrete, wood, aluminum, and PVC\u003c\/li\u003e\n  \u003cli\u003eGray color suits precast concrete and masonry applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on heavy and light precast panel expansion joints, wood, aluminum, and PVC substrates in general construction sealing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplication is typically performed by licensed contractors or skilled trades professionals working on building envelope and structural joint sealing. Before applying, ensure the substrate is clean, dry, and free of dust, oil, and loose material for proper adhesion. Apply using a standard caulking gun and tool the joint within the skin time window. Follow applicable local building codes and the manufacturer's surface preparation guidelines for best results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealant Type\u003c\/strong\u003e: Single-component polyurethane elastomeric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 10.5 fluid ounces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElongation\u003c\/strong\u003e: Over 600 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSkin Time\u003c\/strong\u003e: Approximately 2 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011628233\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100200170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346205507890,"sku":"7100200170","price":141.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523448.jpg?v=1782073853","url":"https:\/\/voomisupply.com\/products\/3m-7100200170-polyurethane-construction-sealant-525-gray","provider":"Voomi Supply","version":"1.0","type":"link"}
