Polyurethane waterproof coating shelf life? w¥€φhat are the advantages of polyurethane coat₹∏∏"ing?
The film-forming substance of polyσ urethane waterproof coating is an isoγ←cyanate-terminated p↓>★olyurethane prepolymer formed by Ωthe polymerization of polyether polyol and iso&÷↑✔cyanate. It is a high-grade waterproof✔™α coating with simple construction, good cor§♠rosion resistance, oil resistance, strong 'adhesion, and excellent high and low tempe★ rature performance. polyurethane wat&≈Ωerproof coating shelf life is₹β♥ how long? what are theδ>φ advantages and disadvantag↓αes of polyurethane coating?

Disadvantages of polyurethane w¥™ aterproof coating
1, waterborne polyurethane waterprαγαoof coating construction temperatur☆©e should be 5 ℃ to 35 ℃. 2, whλγ©en using, do not mix water or ∞βother materials in this produ ®•ct. 3. Please use appropria ¶®¶te protective measures during con ∑struction, such as gloves. 4,αλ£♦ good weather resistance, high temperature do©' ★es not flow, low temp♥©σ→erature does not crack, excellent anti-agingλ € performance, oil resistance, wear ε$♥resistance, ozone resistance, acid and alkal♠¥∞¶i erosion. 5. The prepared slurry of wate∏ε£rborne polyurethane should be• used up within 1 ho₹✔≠ ur. 6, polyurethaneσΩ waterproof coating environmental protectio↑ n is relatively poor, pungent ↔✔®smell. Therefore, the avΩ£erage family uses more morning light waterproo←≈"f coating and acrylic waterproof c≠>oating at home. Advantages: 1, the✘σ wear resistance of the paint film is stron∏®'↕g, polyurethane coating is all γ₩₽kinds of coating wear resistance is better,§•< at the same time excellent protection and bea<♦utiful decoration. 2. The adhesion ≤∑of polyurethane paint film is strong. 3. T'€he hardness adjustment range of the pai↕φnt film is wide. 4, t∑>he construction of good adaptability, 0 ℃, ≈$Ω©room temperature, high temperature can π $be cured. 5. The pa×<✘int film has good temperatur$e resistance and can be made into hi ©gh temperature resistant insulating pε©©aint with low temperature resistance of -40 Ω÷℃. 6, has excellent chemical resistance and ¥≈oil resistance.
