Strong Adhesive Waterproofing Materials Liquid Rubber Roof Coating  

 

 Non-cured rubber bitumen coating is a single-component coating made from rubber, asphalt and other materials by adding polymer 

modifiers, additives. It is not curable after long-term exposure in air, holding a viscous gum state. the forming waterproof layer won't be 

damaged due to structural deformation and damage of stress.

 

        

In the waterproofing works, the use of non-cured rubber asphalt waterproofing coating with self-adhesive membrane is a composite 

technology, which can greatly improves the quality of roofing projects, especially for large deformation projects and high rating requirements 

on waterproofing.

  Advantages               

1. Solid content: free of volatile solvent, solid content up to 98%.

2. Eco-friendly:maintain the original sticky gum-like after construction, non-toxic, tasteless and non-polluting at room temperature.

3. self-healing:self-healing even if the waterproof layer appearing dead pixels,preventing water flows in waterproof layer.

4. Adhesion: strong adhesion with substrates like wood, cement, glass,metal and difficult to peel.

5. Creep properties: excellent creep properties, effectively sealing minor cracks on grassroots level, to improve durability of the

    waterproof layer.

6. Adaptability: excellent acid, alkali, salt and heat resistance, meet waterproofing requirements of various types of construction projects

7.Flexible application:well applied on damp ground,no need for maintenance and shorten application period. not only as a single

   waterproof coating layer, or used as an adhesive material for all kinds of waterproofing membrane.

 

  Product Application                          

Non-cured Rubber Bitumen waterproof Coating+self-adhesive membrane(1.5mm thk) 

Self-adhesive membrane can choose three kinds of materials:

 

1. DCPS self-adhesive membrane

2. Strong cross film polymer self-adhesive membrane 

3. DYC self-adhesive membrane

  

  Application attention                         

 

1. spraying non-cured rubber asphalt waterproof coating:

With special sprayer evenly spraying non-cured rubber bitumen coating and normally forming a waterproof layer thickness of 2mm. After spraying, promptly covered waterproof membrane, avoid excessive dust bonded to the surface and reduce the adhesion between coating and waterproof membrane .  Can walk on it directly without waiting after the finishing of paving isolation layer or waterproof membrane.

 

2. laying self-adhesive waterproofing membrane

For special places like the corners of plane and facade, scratching the coating with thickness of 2mm, and attaching a 

correspondingly shaped membrane. The width of noncured rubber bitumen coating should be slightly wider than the width of the waterproofing membrane. Stones roll and hold the waterproofing membrane from one to end, evenly forward Stones, Calibrating, driven out of the bubble, lap length not less than 100mm. 

 

3. sealing the joints with same self-adhesive membrane at width of 100mm.
