Silicone Rubber Waterproof Coatings

Oct 19, 2020

Silicone rubber waterproof coatings are emulsion-type waterproof coatings prepared by mixing silicone rubber emulsions and other high molecular polymer emulsions as the main raw materials, mixing appropriate chemical additives and fillers, etc., and uniformly mixing them. The coating has good permeability, film-forming properties, water resistance, elasticity, adhesion, high and low temperature resistance, etc., and can be used for construction operations on dry or wet bases without clear water.
Pros and cons
1. The coating is a highly elastic emulsion material made of water as a dispersion medium. It has no irritating odor, non-toxic, no environmental pollution, safe and reliable during production and construction.
2. Coating can be carried out under normal temperature conditions, and it is easy to form a continuous, elastic, seamless, and integral waterproof coating film.
3. The coating film has high tensile strength, high elongation at break, strong adaptability to expansion or cracking deformation of the base layer, good weather resistance, and long service life.
4. The main disadvantage of silicone rubber waterproof coatings is that the solid content is lower than that of reactive curing coatings. To achieve the same coating film thickness, not only the number of painting and construction passes are large, but also the amount of coating per unit area is large and the cost is high.
Use range
Silicone waterproof coatings are mainly used for waterproofing of underground projects, toilets, reservoirs, and roofs. But the thickness of the waterproof layer of the coating film must meet the requirements of the specification.
Superior features
It can be constructed on a variety of base surfaces such as wet and dry, with long service life, weather resistance, aging resistance, oil resistance and a certain degree of acid resistance, superior waterproof performance, non-toxic, odorless, non-polluting, safe and simple construction, short construction period, etc. advantage. It is an ideal material for class 1 waterproofing.
Adaptation:
Various industrial and civil buildings, toilets, kitchens, roofs, gutters, balconies, exterior walls, basements, pools, sewers, mines, tunnels, bridge grouting joints, irrigation expansion joints and other waterproof, moisture-proof, anti-corrosion projects. Smear with tiles and cracks in external walls to block water seepage.
Silicone rubber waterproof coating has good water resistance, permeability, film-forming properties, elasticity, cohesiveness, water resistance and humidity resistance. It is suitable for waterproofing, anti-seepage and leakage repairing projects of underground projects and roofs. It is also an excellent vapor barrier material for cold storage.
Construction methods:
After the powder and emulsion are mixed, a chemical reaction occurs, which penetrates into the pores of the substrate, and merges with the substrate to form a crystalline and dense waterproof layer, which seals the passage and penetration of water to achieve a waterproof effect. It should be criss-crossed and back and forth repeatedly. The time interval between the layers shall be the previous layer without touching your hands. After the first layer is dry, scrape the next layer. In flooding, expansion joints, gutters, etc., they are important or need special In the treatment area, the carcass can be added for reinforcement treatment, and the protective layer or other covering layer can be used after the waterproof layer is completed.
