PU-COAT TOP aliphatic protective layer

PU COAT TOP

Aliphatic polyurethane waterproofing protective layer

PU-COAT TOP is a single-component, solvent-based liquid coating based on aliphatic polyurethane resins. This coating has exceptional resistance to UV rays and abrasion, providing surfaces with long-lasting protection and an aesthetic appearance.

Why choose PU-COAT TOP?

• UV resistance and color stability: Unlike standard polyurethanes, this aliphatic coating does not chalk, does not yellow, and retains its color even when exposed to direct sunlight.

• Mechanical resistance: Excellently withstands pedestrian and vehicle traffic, is resistant to friction and mechanical loads.

• Elasticity: Maintains elasticity and working deformations over a wide temperature range (from -40 °C to +80 °C ).

• Durability: Successfully passed 2000 hours of accelerated aging tests (UV and humidity cycles) without any changes in mechanical properties.

• High hydrophobicity: Provides excellent resistance to water and moisture.

• Aesthetics: Gives the surface a glossy and color-stable finish.

AREAS OF USE

Used as a protective top layer on PU-COAT membrane:

• Terraces and verandas.

• Pedestrian paths and sidewalks.

• Open parking lots.

• Stadiums and other public spaces where wear resistance is required.

TECHNICAL CHARACTERISTICS

• Consumption: When used as a top coat – 150 – 250 g/m² (depending on surface roughness).

• Skin formation: Surface skin formation within 2 hours (at 23 °C).

• Hardening time: 12 – 24 hours.

• Elasticity: Elongation at break – 150% .
