HCA-104 Acrylic Coating for Building Exterior

Brief Introduction:
1. "Yuhong" HCA-104 acrylic elastic coating for building exterior is a kind of functional coating made by using special high polymer emulsion
2. Adopt self crosslinking pure acrylic acid emulsion (elastic and antipollution) as the base material, mixed with high-quality pigment, filling and various assistant agents

Features of HCA-104 Acrylic Coating for Building Exterior:
1. Good elasticity, durable toughness and marked elongation to adapt to the forming and change of the (live) cracks on the surface of buildings
2. Improved staining resistance
3. Better durability, prominent weathering resistance and anti-ultraviolet radiation
4. Environmentally friendly water paint, without any pollution
5. Liquid state, cold construction, safe and convenient

Applications:
1. Used as both functional coating and decorating coating
2. Applicable to the protective coatings of the external heat insulation system of exterior wall and other exterior wall coatings
