Technical Datasheet One-component, aliphatic polyurethane coating. TOPcOaT-pU 720 is used for the protection of exposed polyurethane waterproofing coatings, especially if a dark final color has been chosen. Forms a UV-stable, waterproof membrane and offers the following advantages: • Simple application (one-component product). • Color stability. • A glossy and easy-to-clean surface, resistant to light pedestrian traffic. • Resistance to frost. • Maintenance of its mechanical properties over a temperature span of -40oC to +90oC. Certified according to EN 1504-2 and classified as a coating for surface protection of concrete. Certificate No.: 2032-CPR-10.11. Also certified according to EN 13813 and classified as synthetic resin screed. CE marked. TOPCOAT-PU 720 is used for the protection of polyurethane waterproofing coatings from: • UV exposure, especially when a dark color has been chosen. • Pedestrian traffic and light vehicle traffic (e.g. parking decks) Furthermore, it can be used for the protection of metal and concrete surfaces. prepolymer Colors: white, grey Properties of the cured membrane Elongation at break: 130% (ASTM D412) Hardness according to SHORE D: 57 Water impermeability at hydrostatic pressure: 5 atm (DIN 1048) Solar Reflectance (SR): 88% (ASTM E903-96) Infrared Emittance: 0.91 (ASTM C1371-04a) Solar Reflectance Index (SRI): 112 Abrasion resistance (EN 13892-4 (BCA)) AR 0.5 Water vapor permeability: (EN ISO 7783-2, Class I, Sd < 5m) Artificial weathering: (EN 1062-11, after 2000 h) Service temperature: Pass (no blistering, cracking or flaking) from -400C to +900C

Tools should be cleaned with SM-16 solvent, while TOPCOAT-PU 720 is still fresh. 1. Substrate preparation The substrate must be completely dry, clean, free of grease, loose particles, dust, etc. Existing polyurethane waterproofing coatings do not require priming. 1.1 Metal surfaces Metal surfaces should be: • Dry and clean. • Free of grease, loose particles, dust, etc. that may hinder adhesion. • Free of rust or corrosion that may hinder adhesion. Having been prepared by brushing, rubbing, sandblasting, etc. and then thoroughly cleaned from dust, metal surfaces are primed with the...
