Product Description

OTAi pre-applied HDPE membrane is a multilayer compound waterproof material with excellent performance. It includes one layer of high density PE film, one layer hot-melt pressure sensitive polymer adhesive and one insulation layer. It is widely used on flat concrete surface or compacted sandy layer as well as waterproof layer of vertical surface of temporary and adjacent structures to form continuous and permanent combination.

Characteristics

1. When casting concrete, the concrete mortar and material are combined to form a special macro molecular polymer to make curing reaction adhering, so that coiled material structure is adhered together permanently. No water fleeing inside the structure, and increase the reliability of waterproof layer.

2. It has strong self-healing ability and can repair slight construction injury.

3. High strength of elongation, strong breaking tensile strength and good anti-perforation performance.

4. With strong chemical resistance to acid and alkali.

5. Integration of self adhesion, waterproof and protection, so that can reduce construction links.

6. Wet method construction, no need flat layer, low requirement for the base, not affected by weather and base moisture, it has obvious advantage of constructions in rainy season.

7. The floor board of the building should be constructed with a pre-applied anti-sticking method. This method no need protective layer.

8. One layer can reach level one waterproofing security requirements.
 

STORAGE AND TRANSPORTATION
 

Moving, transporting, storing and using materials should avoido bjects and environments which easily cause perforation or physical damage.
 

Different types of products should be classified and stored in parallel, with a height of no more than 5 layers.
 

The finished products should be sealed and packed using clean waterproof cloth to protect, and put it in a high place, such as pallet or wood.
 

All flammable materials should be stored in a cool and dry place, far from spark and fire.
