Product Description

Polyurethane waterproof coating is two-component reaction type of synthetic polymer waterproof coating,from A component and B component composition.A component is the polyester and isocyanate by condensation polymerizatiob get polyurethane prepolymers,team B is made of curing agent,thickening agent, chain extension agent,filling agent composed of liquid.When using will be A,B components is 1:1 mixture,stir,scraping coat should be in the construction base plane,after several hours after the reaciton consolidation become continous,elastic,tenacity and durability of the waterproof coating layer.

Application Scope
This product is suitable for all kinds of building roofing waterproof:culvert,bridge,the subway,the basement project and waterproof;all kinds of building expansion joint,wall tube,or(water holes) to detail structure of the seal processing; Iron and steel corrosion and anticorrosion engineering of the pool.

After processing the base root, mix the A and B components according the weight proportion of 1:1 and fully mix them inactive.It can be used by several basmear brushes paint construction method.
