Overview
KingSeal PU165 is a one component, non-sag polyurethane sealant that cures by reacting with air humidity to form a high-performance and highly elastic low modulus sealant capable of cyclic expansion and compression movement of (± 50%) of the original joint width. KingSeal PU165 has a very wide service temperature range. Suitable for vertical and horizontal joints.
Applications
- Sealing of expansion and construction joints
- Precast concrete elements
- For concrete, wood, marble, stone, aluminum, steel, ceramic, gypsum boards, etc
Advantages
- High movement capability of ±50
- One component
- Excellent weathering and aging resistance
- Paintable
- Remains elastic at temperatures down to -40oC
- Good adhesion to most surfaces without need for
