Polyurea Coating Primer

Polyurea coating primer procedure on concrete      The polyurea coating primer has excellent shielding, abrasion resistance, chemical resistance and UV resistance, which polyurea coating on concrete is fully protect from moisture and various external corrosion factors. Which polyurea coating procedure very low VOC emissions can be achieved during the coating process, high construction efficiency, environmental protection and resource saving. Feature of Polyurea Coating Elongation rate: 200-1000%Tensile Strength: 10-30PMPaAdhesion with cement: 4.5MPaWaterproof life more than 50 years Excellent bonding properties Excellent self-healing Excellent Waterproof and anti-corrosion properties Excellent chemical resistance and aging resistance Item Requirement Item Requirement Adhesion ≥ 4.0MPa(or substrate broken) Density(film) 1.1g/cm3 Tensible Strength 10-20MPa Solid Content(%) 95-100% Elongation at Break 300-500% Construction Period(25℃) 30-60min Tear Strength ≥70kN/m Dry Film Thickness 600-2000µm Hardness(Shore A) ≥80 Theoretical Coverage 1.0kg/m2(when dry film is 900µm) Low Temperature Bendin -40℃ Surface Drying 1h Wear Resistance(750g/500r) ≤0.03g Actual Drying 24h Re-coat Time 12-48h Color : gray or as required Gloss  : semi matte Construction Methods : Brush, roller,airless spraying Mixing : waterproof coating:curing agent=1:1 (please see label notice) Polyurea Waterproofing Coating Applications:
