APPLIACTIONS

Highlights

1.EASY VERSATILE APPLICATION: Apply self-leveling concrete pu sealant to expansion joints without concern for uneven surfacing. Perfect for driveways, garages, sidewalks, or pavement

2.TOP CHOICE FOR CONCRETE JOINTS CAULKING: Perfect for use as a concrete self-leveling compound on driveways, warehouses, factories, and civil structures. Narrow tip makes for easy and accurate application

3.EXCELLENT SELF-LEVELING PERFORMANCE: Formulated for horizontal surfaces, this polyurethane sealant automatically flows into gaps, ensuring a perfectly smooth, uniform, and professional finish on concrete floors without manual tooling.

4.HIGH ELASTICITY & MOISTURE CURED: Cures into a tough, highly flexible, and elastomeric seal (Elongation at break > 400%). Effectively absorbs joint movement and resists tearing, cracking, or abrasion under heavy traffic.

5.ALL-WEATHER & CHEMICAL RESISTANCE: Engineered for both indoor and outdoor applications. It withstands intense UV rays, extreme temperatures, moisture, and harsh chemical exposure (fuels, oils), making it ideal for garage floors and industrial pathways.

6.VERSATILE CONCRETE JOINT FILLER: The perfect heavy-duty caulking solution for expansion joints, driveways, sidewalks, warehouses, factories, and civil structures. It delivers exceptional adhesion even in submerged conditions like canal or reservoir joints.

7.DIRECT FACTORY OEM/ODM SERVICES: Manufactured by a Top 10 silicone & PU sealant factory in China with ISO9001/14001 certification. We offer full private label support, customized colors, tailored formulations, and agile packaging to fit your brand needs.

8.Good Adhesion: polyurethane based, high performance, moisture cured and elastomeric sealant. Not only for most construction materials, but also for submerged conditions, such as canal and reservoir joints.

1. Joints in rigid pavements of airports and concrete roads
2. Joints in concrete floors
3. Indoor and outdoor applications for pedestrian and traffic areas (petrol station, decks, car parks)
4. Floor joints in warehouses and production areas
5. Joints in waste water treatment plants (Please check with our Technical Department before use)
6. Floor joints in tunnel construction
