KingProof PUP®
Polyurethane liquid membrane for protection of KingProof range.
Overview
KingProof PUP is an aliphatic one-component polyurethane liquid membrane which cures upon exposure to the humidity in the atmosphere producing a hydrophobic transparent membrane with excellent mechanical properties. KingProof PUP is highly resistance to UV radiation and will not be affected from direct exposure to sunlight.
Applications
- KingProof PUP is recommended to be used as a top-coat over KingProof membranes to protect the colour from changing after exposure to direct sunlight as well as maintaining and improving the mechanical properties of the membrane. KingProof PUP can also be used to protect concrete and synthetic coats
Advantages
- Excellent heat and UV resistance
- High mechanical properties and chemical resistance
- Highly hydrophobic polyurethane resin
- Wide service temperature range
- Cold resistance, the membrane stays elastic down to minus 30oC
