Once cured, it forms a flexible, resilient joint with strong adhesion to most common building materials. It delivers an elongation rating of over 600 percent and a Shore A hardness of 25, making it well suited for joints that experience significant movement or thermal cycling. Skin time is approximately 2 hours. This product ships in a 50-gallon open head lined drum, intended for high-volume application on commercial or industrial construction projects. Licensed applicators and sealant contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis sealant is formulated for creating flexible seals on expansion joints in heavy and light precast concrete panel assemblies. It also performs on wood, aluminum, and PVC substrates, covering a wide range of building envelope applications. The drum format is suited to gang-pour or bulk-dispensing operations on large job sites where cartridge volume would be impractical. It is appropriate for both horizontal and vertical joint applications where a gray color match is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-component moisture-cure polyurethane — no mixing required prior to application\u003c\/li\u003e\n  \u003cli\u003eElongation exceeding 600 percent for joints subject to high movement\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 25 — soft, flexible cure profile\u003c\/li\u003e\n  \u003cli\u003eApproximately 2-hour skin time allows working time adjustment in field conditions\u003c\/li\u003e\n  \u003cli\u003eCompatible with precast concrete, wood, aluminum, and PVC substrates\u003c\/li\u003e\n  \u003cli\u003e50-gallon open head lined drum format supports high-volume bulk dispensing\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 and bonding to wood, aluminum, and PVC substrates in commercial and industrial construction sealant applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplication should be performed by a qualified sealant contractor or construction trade professional familiar with ASTM joint-sealant standards. Surfaces must be clean, dry, and free of dust, oil, and loose material before application. Do not apply to wet or frozen substrates, as moisture-cure kinetics will be affected by surface conditions. Bulk dispensing from a drum requires compatible pumping equipment rated for single-component polyurethane sealants.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Single-Component Polyurethane Elastomeric Sealant\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: 50 Gallon Open Head Lined Drum\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\u003eCure Mechanism\u003c\/strong\u003e: Atmospheric humidity cure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 526.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 34.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 22.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 22.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 50051111080165\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: 7100200220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346730582322,"sku":"7100200220","price":21366.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523925.jpg?v=1782088680","url":"https:\/\/voomisupply.com\/products\/3m-7100200220-polyurethane-sealant-525-gray-50-gal-drum","provider":"Voomi Supply","version":"1.0","type":"link"}
