Water-based polyurethane waterproof coatings

※  Product Description

Our Water-Based Polyurethane Waterproof Coating is a high-performance solution designed to provide exceptional waterproofing and protection for various surfaces. Formulated with advanced water-based polyurethane technology, this eco-friendly coating offers a durable, flexible, and abrasion-resistant finish, making it ideal for both indoor and outdoor applications.

※  The name of Polyurethane Waterproof Coating

Water-Based Polyurethane Waterproof Sealant/Aqueous Polyurethane Coating/Waterborne Polyurethane Coating/水性ポリウレタン防水塗料 (Mizusei Polyurethane Bōsui Tōryō)/Water-Based Polyurethane Coating/Water-Based Polyurethane Sealer

※  Executive Standard

JCT864-2008

※  Application

 1.Wall surface, basement, tunnel, kitchen, swimming pool, subway, bathroom and so on.

      2.Especially used for the place where the shape is complex and irregular. 

※  Material Features

1. One-component pu membrane coating. Easy to handle and apply.

 2. Physical properties of the solidified film are featured with high-strength, high elongation, high-Resilience, good anti-fatigue, and high aging resistance.

 3. Excellent weatherability, so that SPU pu coating waterproof can be adaptable to climate changes in regions with hot or cold Weather.

 4. As environment- friendly products, SPU single component polyurethane waterproofing contains no solvent and less volatile organic compounds (VOC), innoxious, odorless, pollution-free, and safe.

 5. By water solidified mechanism, SPU pu water proofing can form into a film on a moist base.

6.Excellent tensile strength and high elasticity,well-adapted to the substrate shrinkage and deformation.

Application

used in the roofs, external walls, basements, balconies, kitchens, and lavatories of general buildings, and even some special edifices such as civil air defense works, bridge projects, and granaries.

※ Construction Requirments

1. Keep the base firm, smooth,clean, no dust, oil and visual water.

 2. Brush directly after stirring SPU Coating evenly.

 3. Brush in large area: Brush SPU on the substrate with rubber scrapper, and guarantee suitable strength, uniformity and no stack.

 4. Recommended thickness is not beyond 0.7mm at per coating film, and two or three times coating film is better.

5. Do the second time's brush after the first film is dry, namely non-stick with hand. Remember the brushing direction is orthogonal with the last film, until reaches the design thickness.

 6. If necessary add some water whose weight is about 10% of the coating, stir evenly not less than 3min by electric mixer.

※ Construction Methods

One Component Polyurethane Waterproofing Coating can use construction methods as below: brushing, roller coating, spraying, etc.

※Storage and Transportation

 1. In a cool, dry place, away from direct sunlight, damp and fire.

2. The storage period is half a year. After the expiration, it shall be tested again. It can be used again after passing the test.

3. Upside-down piling, not more than three layers.

4. The product is a combustible material, so during transportation, great importance shall be attached to safety. Care must be taken against catch-on-fire; 

it must be kept away from rain, insolation, extrusion, and collision. The package shall be kept intact and in compliance with relevant regulations of the transportation

 department.
