Polyurethane waterproof coatings can be divided into one-component and two-component.
One-component polyurethane waterproof coating, also known as moisture-curing polyurethane waterproof coating, is a reactive moisture-curing film-forming waterproof coating. It is applied to the waterproof base layer during use and is cured to crosslink into a tough, soft and seamless rubber waterproofing membrane by reacting with moisture in the air.
High-strength polyurethane waterproof coating is a two-component reactive curing waterproof coating. High-strength polyurethane waterproof coating Two-component chemical reaction-cured isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanic acid. Component B is composed of plasticizer, curing agent, thickener, accelerator, and filler. Composition of colored liquids. When used, the two components of A and B are uniformly mixed in proportion, coated on the surface of the waterproof base layer, and often cured by temperature crosslinking to form a rubber elastic film with high elasticity, high strength and durability, thereby waterproofing.
The waterborne polyurethane waterproof coating generally refers to the one-component polyurethane waterproof coating, and the oily refers to the two-component polyurethane waterproof coating; in comparison, the water performance is almost the same, the price is also cheaper, the most important thing to look at the use environment! However, waterborne polyurethane waterproof coatings are more environmentally friendly.
Single Component Polyurethane Waterproof Coating
Film Thickness Dosage
Knife-coat; Roller coating; Spray
25kg/ barrel; 20'ft container: 450 barrels, 11.25 tons.
Red or customized
Widely used in roofs, basement, toilet, swimming pool, and all kinds of industry and civil building waterproofing.
1) Substrate need be firm, smooth, no sundries, inside corner and outside corner should be made into circular arc, the diameter of insider corner should be more than 50mm, and the outside corder should be more than 10mm.
2) Ingredient and dosage: according to application dosage, evenly mixing round o use.
3) Reference dosage: coating film dosage is about 1.3-1.5kg/sqm when the thickness is 1mm.
4) Large waterproof application, coating uniformity mixed coating with a rubber or plastic scraper, the thickness is consistent, generally it is 1.5mm to 2.0mm, should be brushed in 3 to 4 times, the last time brushing should be done after the previous brushing cures and becomes film, and brushing at a vertical direction. Generally as a separate film-forming, for underground project board, should pave a layer of felt reinforced material in addition.Coating thickness: to underground project thickness is 1.2 to 2.0mm, generally 1.5mm; to toilet thickness is not less than 1.5mm; to multilayer waterproof of exposured roof construction thickness is not less than 1.2mm ; to one layer waterproof of grade III waterproof, thickness is not less than 2mm;Fishing layer application.scatter the cleaned sand before the last time brushing is not solidified.
5) Protection layer: on the coating film surface should do insulation protection as the design.
Storage and attention items:
1) Keep materials in the room which is dry and ventilating
2) Avoid direct sunlight when transportation, avoid collisions and attention to fire
3) 6 months from date of production if stored properly in undamaged and unopened original sealed packaging in dry and cool conditions.
(1) It can be directly applied on various wet or dry base surfaces.
(2) The adhesion to the base surface is strong, and the polymer material in the coating film can penetrate into the fine slits of the base surface, and the following type is strong.
(3) The coating film has good flexibility, has strong adaptability to the expansion or cracking of the base layer, and has high tensile strength.
(4) Green, non-toxic, tasteless, non-polluting environment, no harm to the human body.
(5) Good weather resistance, high temperature does not flow, low temperature does not crack, excellent anti-aging performance, can withstand oil, wear, ozone, acid and alkali corrosion.
(6) The coating film is dense, the waterproof layer is complete, no cracks, no pinholes, no bubbles, small water vapor permeability coefficient, and has both waterproof function and gas barrier function.
(7) Simple construction, short construction period and convenient maintenance.
(8) Various colors can be adjusted as needed.
(9) Light weight, does not increase the building load.
