Double-component waterproofing coating

Double-component waterproofing coating

Double-component waterproofing coating belongs to solidify waterproof materials, and Group A is isocyanate-terminated pre-polymer polycondensate by polyether and isocyanate, Group B is a colored liquid composed of plasticizer, curing agent, thickening agent, coagulant agent, and filler, ix Group A and B evenly as rate and brush on the waterproofing substrate surface, form a elastics and rubber-like coating film through cross-linking and solidifying at normal temperature, which plays a role of waterproofing

Characteristic

• Double-component waterproofing coating forms seamless, integrated elasticity waterproof layer solidifying, and improves the waterproof and seeping resistance of the project, which is a waterproof membrane that can‘t be attained. Especially the coating film has high elasticity and elongation, and high adaptability to substrate cracking or expansion.
• Firm bonding with substrate, coating film has extreme bonding power with concrete, timber, metal, pottery, and asbestos shingle, and also can be used as a bond.
• Convenient application, Polyurethane coating film is a cold application waterproof coating, just mix groups A and B at the rate when applied and brush it on the waterproof substrate.
• Easy maintenance, only maintaining the broken parts, which can reach the original effects of waterproofing, save time, save power, and low cost.
• Environmental product, and reduce the damage to the person and environment.

Applicable scope

Widely used in roofs, basements, swimming pools, and all kinds of industry and civil building waterproofing.

Technical property

[ Execute standard GB/T19250-2003]

Application technology

• The substrate needs to be firm, and smooth, with no sundries, inside corner, and outside corner should be made into a circular arc, the diameter of the inside corner should be more than 50mm, and the outside corder
• Should be more than 10mm.;
• Ingredient and dosage: according to application dosage, evenly mixing round o us.
• Reference dosage; coating film dosage is about 1.3-1.5kg/sqm when the thickness is 1mm.
• 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 a 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: For underground project, the thickness is 1.2 to 2.0mm, generally 1.5mm; to toilet, thickness is not less than 1.5mm; to multilayer waterproof of exposure roof construction thickness is not less than 1.2,; to one layer waterproof of grade Ⅲ waterproof, thickness is not less than 2mm;
• Finishing layer application: Scatter the cleaned sand before the last time brushing is not solidified.
• Protection layer: On the coating film surface, insulation protection is the design.

Attention

• Diluents can’t be alcohol acid, nitro diluents such as paint thinner, don’t touch with water.
• Keep ventilated ration, no fire.
• If the material has a slight disposition, it should be evenly mixed before use
• The construction site must keep good ventilation and should not apply on rainy days;
• Open the cover when used, it must be used up in 40 minutes;
• If find broken coating film on the construction site, dig around the broken opening with a cutting knife, and then brush the waterproofing coating and repair

Storage and attention items

• Keep materials in the room which is dry and ventilate ration
• Avoid direct sunlight when transportation, avoid collisions, and pay attention to fire
• The guarantee period of storage is six months, the coating out of storage time should be used after rechecking
