HS-02 911Polyurethane water proof coating
(two-component)
一、Product introduction：
Hs-02 911 polyurethane waterproof coating is a two-component high molecular reactive chemical waterproof coating with polyurethane as the main body,It is made with isocyanate base (NCO) polyurethane pre polymers (component a) and contains many hydroxyl (OH) - curing agent, carbon black, curing agent, fungicide, tackifier, catalyst and other additives mixtures (component b).After mixing the parts of group a and group b in a certain proportion, the waterproof film with elastic integrity is formed by curing.
二、Product advantages：
1、Cold construction, easy operation, safe construction.
2、Liquid construction, curing at room temperature, short solidification period, strong adhesion, waterproof, anti-seepage performance.
3、High elongation, cold resistance, heat resistance, corrosion resistance, good aging resistance.
三、Scope of application：
1、Waterproofing of various roofing works, such as concrete, bamboo, wood, steel, tile, etc.
3、Waterproof works for underground buildings, such as concrete floor, inner and outer walls, retaining walls, tunnels and pit.
3、Waterproof works of various buildings, such as toilet, kitchen, non-edible pool, swimming pool, flower bed, water lock ground, inner wall, construction seam, expansion joint, wall pipe, water outlet, etc.
4、Bonded corrosion protection: can bond wood floor, cement board, asbestos products;And can be used as pipeline corrosion protection, antiseptic floor, antiseptic tank.
四、The key technical indexes：
· Inspection items | Index | |
· solid content（%） | ≥92 | |
· Time of drying(h) | Touch dry | ≤8 |
Hard dry | ≤24 | |
Foldability at Low Temperature（℃） | · ≤-35crack free | |
· watertightness （0.3Mpa,30min） | waterproof | |
tensile strength（Mpa） | ≥1.90 | |
elongation at break（%） | ≥450 | |
五、Method of construction：
1、Basal Plane Treatment ：The construction surface shall be solid, smooth and dry, free from clear water, dust and oil, and shall be filled and smoothed at the low concave breaking point.
2、Ingredients: according to group a：Material of group b = weight ratio of 1:2. Pour the material of group a into the container and then add the material of group b.
3、construction：The construction of materials is usually carried out in two stage,Apply the mixed paint evenly on the substrate with a rubber scraper or a brown brush,Scratches should be repeated several times in both vertical directions ensuring the penetration and adhesion of the coating on the substrate.When the first layer of coating surface is dried and cured, the second layer of coating can be applied.（Adding glass fiber cloth or non-woven cloth to the coating can improve its waterproof performance).
4、construotion of insulation protection cover：To increase the adhesion between the waterproof layer and the protective layer,sprinkle the surface with coarse sand or fine stone rice before the second layer of coating is cured,then the bond between the protective layer and the waterproof layer can be firm.
5、materials consumption：Thickness of 1mm is about 1.2~1.4kg/㎡, 1.5mm is about 1.7~2kg/㎡, and 2mm is about 2.5kg/㎡
六、matters needing attention：
1、If it's not easy to build due to the viscosity of group b material is found to be too high during construction (especially in winter),A small amount of toluene or xylene allowed added for dilution,the dosage should not be more than 10% of group b.
2、If the prepared coating produces bubbles (usually caused by high moisture content of the substrate),the foaming place should be cut ,so that it can open to expel moisture, and then drying with paint repair.
3、Construction temperature should be above 5 ℃,air circulation should be maintained during construction;The opening coating should be used up within 20 minutes.
4、This product should be sealed and stored in a dry, ventilated place to avoid sunlight and rain, and the storage period is 12 months.
七、product packaging：
The product packaging is 30kg/set
