Description

Crack Flex Sealant Gray Self-leveling Sealant Used to Partially Fill Deep Cracks or Joints

Useal PU 11SL is a kind of polyurethane sealant specially used for filling and sealing the ground gap, with good self-leveling performance, and can automatically level the surface during construction to form a smooth and uniform sealing layer. The appearance of this sealant is a water-like liquid, with fluidity, can flow in deformation joints, suitable for the deformation joints of cement buildings.‌

Applications

It is widely used in urban leisure square ground deformation joint, parking lot, water supply and drainage, airport runway, concrete highway, pool bottom, underground engineering, water conservancy engineering, civil engineering and other horizontal concrete structure deformation joint sealing.

Features

1. Oil resistance, water resistance, aging resistance, friction resistance, high and low temperature (-50℃-120℃): polyurethane self-leveling sealant has excellent chemical resistance and temperature adaptability‌.

‌2. Low modulus, high elongation: suitable for dynamic joints, can maintain good sealing effect in expansion and contraction changes‌.

‌3. Good adhesion: suitable for a variety of base materials, such as mortar, concrete, glass, ceramics‌.

‌4. Low volatile odor: small environmental impact during construction ‌.

‌5. Excellent air tightness and water resistance: can effectively prevent the penetration of gas and liquid‌.

‌6. Convenient construction: can be constructed at any temperature, no need to heat.
