Waterborne Polyurethane waterproof coating
Polyurethane waterproof coatings can be divided into one-component and two-component.
One-component polyurethane waterproof coating, also known as moisture-curing polyurethane waterproof coating, is a reactive moisture-curing film-forming waterproof coating. It is applied to the waterproof base layer during use and is cured to crosslink into a tough, soft and seamless rubber waterproofing membrane by reacting with moisture in the air.
High-strength polyurethane waterproof coating is a two-component reactive curing waterproof coating. High-strength polyurethane waterproof coating Two-component chemical reaction-cured isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanic acid. Component B is composed of plasticizer, curing agent, thickener, accelerator, and filler. Composition of colored liquids. When used, the two components of A and B are uniformly mixed in proportion, coated on the surface of the waterproof base layer, and often cured by temperature crosslinking to form a rubber elastic film with high elasticity, high strength and durability, thereby waterproofing.
The waterborne polyurethane waterproof coating generally refers to the one-component polyurethane waterproof coating, and the oily refers to the two-component polyurethane waterproof coating; in comparison, the water performance is almost the same, the price is also cheaper, the most important thing to look at the use environment! However, waterborne polyurethane waterproof coatings are more environmentally friendly.
Features
Directly Applied
It can be directly applied on various wet or dry base surfaces
Strong Adhesion
The polymer material in the coating film can penetrate into the fine slits of the base surface
Good Flexibility
The coating film has strong adaptability to the expansion or cracking of the base layer, and has high tensile strength
Environmental Friendly
Green, non-toxic, tasteless, non-polluting environment, no harm to the human body
Good Weather Resistance
High temperature does not flow, low temperature does not crack, excellent anti-aging performance, can withstand oil, wear, ozone, acid and alkali corrosion
Highly Densed Film
The coating film is dense, the waterproof layer is complete, no cracks, no pinholes, no bubbles, small water vapor permeability coefficient, and has both waterproof function and gas barrier function.
