Structural Adhesive

Structural adhesive is a key material in construction and home improvement for bonding and sealing, widely used in door and window installation, sunroom construction, curtain wall work, and the fixing and sealing of various building materials. A quality structural adhesive must deliver strong bonding and reliable sealing, while remaining stable under long-term exposure to sun, rain, and temperature changes—without cracking, peeling, or aging. This structural adhesive is available in two types to suit different application needs: MS adhesive, based on modified silane polymers, offers a broad bonding range, excellent elasticity, and strong weather resistance, making it ideal for curtain walls, doors, windows, and sunrooms where long-term durability matters; water-based adhesive uses water as the dispersion medium, providing low odor, good environmental performance, and easy application, which suits indoor use and projects with higher environmental requirements. Both types combine bonding and gap-filling functions in one product.

In terms of product forms, this structural adhesive comes in soft cartridge and hard cartridge packaging. The soft cartridge works smoothly with a standard caulking gun, delivering even, continuous bead output that suits large-area application; the hard cartridge is convenient for small-area repairs and fine detail work. Net weights of 750 g and 800 g are available per cartridge, so you can choose the right size for your project. In terms of color, white, black, and transparent are offered as standard options, and other colors can be customized on request, allowing the sealant to match different profiles, glass, and curtain wall panels with minimal color difference after application.

For contractors and DIY users alike, the dual function of this structural adhesive—bonding and gap filling—means fewer products to stock and simpler application on site. It grips firmly to common substrates such as aluminum profiles, glass, steel, stone, and coated boards, forming a flexible, durable joint that absorbs movement caused by temperature changes and building settlement. The bead can be tooled smoothly for a neat finish, and excess material wipes away easily before curing. When stored in a cool, dry place in its original sealed cartridge, the product retains full performance throughout its shelf life, and an opened cartridge can be resealed for later use. With standard white, black, and transparent options plus customized colors, matching the sealant to the surrounding structure has never been easier, which helps deliver a clean, professional appearance on every job.

From a manufacturing and quality-control perspective, this structural adhesive is produced under strict process control: raw materials are precisely weighed and fully mixed to ensure consistent bonding strength and extrusion performance from cartridge to cartridge; finished products undergo curing performance, tensile adhesion, and weather-aging tests to guarantee that they will not crack, chalk, or lose elasticity in real-world service. Whether it is door and window installation, sunroom sealing, or curtain wall bonding and gap filling, this structural adhesive delivers durable, reliable bonding and sealing for every project you undertake.

Technical Specifications

Product Type: This product is available in two series: MS adhesive and water-based adhesive. MS adhesive is based on modified silane polymer and cures neutral with low odor and no corrosive release, suitable for metals, glass, stone, and various coated substrates; water-based adhesive uses water as the dispersion medium, featuring low odor and good environmental performance, suitable for interior applications where odor sensitivity matters.

Packaging & Net Weight: The product is supplied in soft cartridge and hard cartridge packaging, with a net weight of 750 g or 800 g per cartridge. The soft cartridge is designed for continuous application with a standard caulking gun with controllable output; the hard cartridge suits repair work and localized application.

Color: Standard colors are white, black, and transparent; other colors can be customized and must be confirmed with the order. Color selection should consider the substrate color to minimize visible color difference after curing.

Function & Application: The product serves both bonding and gap-filling functions, suitable for sealing and fixing in door and window installation, sunroom construction, and curtain wall work; bonding joins building materials, while gap filling closes joints for waterproofing and dust protection.

Storage & Use: Store in a cool, dry place away from direct sunlight; after opening, use promptly and reseal. Clean the substrate surface before application, ensuring it is free of oil, dust, and moisture for reliable adhesion.
