Polyurethane Waterproof coating/paint1.raw material: polyurethane2.color:any3.feature: green & environment friendly
1.Feature: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.
2.Specifications:1).technical standard:JC/T500-92(96)2).tension strength: ≥ 1.65MPa.3).fraction elongation: ≥ 350%4).cold flexibility:-30 ± 1 2h no crazing5).weather impermeability:0.3MPa 30min no leakage6).application time: ≥ 20min7).solidification time:surface<4h,total ≥ 12h.8)solid percentage: ≥ 94%.3.Usage: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.5.Note:1).the storage place should be dry,aerating and avoid water.2).it is forbidden to contact fire because the easy is easy to burn .3).stir the paint homeogeneously before application if Group II materials is found to be of some precipitate.4).the finished paint waterproof layer should be protected well to avoid damage befor the applcation of protection layer.In case the paint layer is found to be damaged ,cut down around the place torepair with paint.
