In construction projects, one of the most commonly overlooked factors is the sealant\u2019s \u201cmovement class.\u201d Selecting the wrong class can lead to premature failure, cracking, delamination, and even water infiltration issues.<br \/>\nTengyu Chemical supports contractors and distributors in selecting suitable sealant systems for different construction conditions.<br \/>\nDifferent types of building joints have varying requirements for a sealant\u2019s movement capacity. This guide explains how sealant movement requirements vary across different applications.<\/div>\n<h2><span style=\"font-size: 95%;\">What is a Sealant Class?<\/span><\/h2>\n<div>Sealant class describes how much joint movement a sealant can accommodate while maintaining adhesion. The higher the class, the greater the range of movement the sealant can accommodate.<\/div>\n<div><\/div>\n<div><strong>Joint movement is caused by:<\/strong><\/div>\n<ul>\n<li>Temperature fluctuations;<\/li>\n<li>Thermal expansion and contraction of materials;<\/li>\n<li>Structural loads;<\/li>\n<li>Vibration;<\/li>\n<li>Extreme weather conditions.<\/li>\n<\/ul>\n<h2><span style=\"font-size: 95%;\">Low-movement applications<\/span><\/h2>\n<div>Low-movement grade sealants are primarily used for joints in structurally stable applications or where only minimal movement occurs. The focus is on waterproof sealing and crack repair, rather than accommodating structural deformation.<\/div>\n<div><strong>Typical Applications:<\/strong><\/div>\n<ul>\n<li>Lightweight concrete joints indoors and outdoors<\/li>\n<li>Non-load-bearing brick wall joints<\/li>\n<li>Joining small precast components<\/li>\n<li>Residential foundation sealing<\/li>\n<\/ul>\n<div><strong>Recommended Products:<\/strong><br \/>\n\u2714<a href=\"https:\/\/www.tengyusealant.com\/vi\/manufacturer\/waterproof-polyurethane-sealant\/\"> TP610-25LM PU Construction Sealant<\/a><br \/>\n\u2714 <a href=\"https:\/\/www.tengyusealant.com\/vi\/manufacturer\/self-leveling-polyurethane-sealant\/\">TP630 Self-Leveling PU Sealant<\/a><\/div>\n<h2><span style=\"font-size: 95%;\">Medium to high-movement applications<\/span><\/h2>\n<div>Capable of accommodating significant thermal expansion and contraction as well as structural micro-movements, suitable for outdoor and long-term exposed environments.<\/div>\n<div><strong>Ideal Applications:<\/strong><\/div>\n<ul>\n<li>Building exterior walls and structural joints<\/li>\n<li>Bridge and tunnel engineering<\/li>\n<li>Roofing and drainage systems<\/li>\n<li>Hydraulic engineering structures<\/li>\n<li>Storage tanks, containers, and industrial facilities<\/li>\n<\/ul>\n<div><strong>Key Advantages:<\/strong><\/div>\n<ul>\n<li>Provides long-term flexibility under thermal movement.<\/li>\n<li>Excellent UV resistance<\/li>\n<li>Long-term durability<\/li>\n<\/ul>\n<div><strong>Recommended Products:<\/strong><br \/>\n\u2714 <a href=\"https:\/\/www.tengyusealant.com\/vi\/manufacturer\/construction-polyurethane-sealant\/\">TP680 Moisture Cure Polyurethane Sealant<\/a><br \/>\n\u2714 <a href=\"https:\/\/www.tengyusealant.com\/vi\/manufacturer\/one-component-polyurethane-sealant-for-aluminium-window\/\">TP690 Modified Polyurethane Concrete Crack Sealant<\/a><\/div>\n<h2><span style=\"font-size: 95%;\">High-movement \/ critical applications<\/span><\/h2>\n<div><strong>Special Applications:<\/strong><\/div>\n<ul>\n<li>Subway and tunnel engineering<\/li>\n<li>Basement waterproofing systems<\/li>\n<li>Building expansion joints<\/li>\n<\/ul>\n<div><strong>Advantages:<\/strong><\/div>\n<ul>\n<li>Ultimate performance<\/li>\n<li>Outstanding movement adaptability<\/li>\n<li>Extremely long service life<\/li>\n<li>Provides higher safety for high-risk projects<\/li>\n<\/ul>\n<div><strong>Recommended Products:<\/strong><br \/>\n<a href=\"https:\/\/www.tengyusealant.com\/vi\/manufacturer\/water-swelling-polyurethane-sealant\/\">TP640 Water-swelling Polyurethane Sealant For Expansion Joints<\/a><\/div>\n<div><\/div>\n<div>Our technical team supports product selection based on project conditions and application requirements.
