polyurethane roof waterproof coating - Polyurethane Waterproof Coating for subways

Polyurethane Waterproof Coating

High-strength & High-elasticity Polyurethane Single-component Waterproof Coating ( Environment-friendly) Is flexible waterproof coating with isocyanate and Polyether polyol as principal raw material plus some additives and fillers by polyaddition reaction.

By coating it on the base and through the polyurethane prepolymerization reaction between NCO Terminal group and the moisture in the air, it form into a layer of rubber waterproof film on the base surface, which are toughened, flexible, seamless.

It forms an elastic waterproof layer like rubber membrane after solidifying at normal temperature.It enjoys many good featureas follows:
1. simple application,reliable performance,no joint gap.
2.good cold&heat resistance,grease-proof&wearpoof,ageing\resistance,and corrosion resistance.
3.firm adhesion and good enlongation.
4..good weaterproofing,not dissolved in weater,and it can be used together with cement and talc powder.

1.It is especially suitable to irregular roof waterproofing such as slanting roof, gutters canopies,etc.
2.It is also widely used in the waterproofing and leakproofing of undergroup projects, inner external walls,kitchen and bathroom,swimming pool,etc.
3.It can be used to connect the gap between metal pipelines and concrete as well as the sealing waterproofing of concrete parts.
4.other waterproofing,corrosion resistance and adhesion,etc.
4.Application:Pour Group I(transparent liquid)and Group II(black or colourful liquid) intoa clean and dry vessel at the weight rate of 1:2or1:1.5,then stir 3minutes to make them mix well for reaction,It is requested to use up within half an hour at the temperature of over 0 For 2mmthick waterproof layer ,it needs to paint 2tims --first time use 30%paint while second time 70%.For over 3mm thick waterproof layer ,paint 3 times--everytime use one third paint
