PVC waterproof coil is a polymer coil formed by the combination of double-sided POLYvinyl chloride plastic layer and polyester reinforcement in the middle through special extrusion and coating process. Formulated polyvinyl chloride plastic layers are combined with polyester fabric with mesh structure to provide excellent dimensional stability and low coefficient of thermal expansion. Improve the long-term performance of the coil directly exposed to the natural environment.

Product features:
1.Can be in the wet or dry various base surface directly construction.
2. strong adhesion with the base surface, the polymer material in the film can penetrate into the base surface fine seam, strong follower.
3. The film has good flexibility, strong adaptability to expansion or cracking of the base, and high tensile strength.
4. Green environmental protection, non-toxic, tasteless, pollution-free environment, no harm to the human body.
5. Good weather resistance, no flow at high temperature, no cracking at low temperature, excellent anti-aging properties, oil resistance, wear resistance, ozone resistance, acid and alkali erosion.
6.the film is dense, the waterproof layer is complete, no cracks, no pinholes, no bubbles, water vapor permeability coefficient is small, both waterproof function and gas function.
7.Simple construction, short construction period, convenient maintenance
8. According to the need, can deploy a variety of colors
9. Light weight, does not increase the load of the building
Construction requirements:
1. The base surface is flat, clean, no sand, loose, moisture content is less than 8%.
2. Construction should be carried out first base acceptance, to ensure that meet the requirements, first coated with a layer of adhesive, adhesive must be uniform.
3. Adhesive curing, second brushing, brushing direction and the previous vertical cross, to prevent leakage of scraping, brushing three to five times.
4. After completion, the waterproof layer is not solidified before, shall not people, shall not carry out the next process, so as not to destroy the waterproof layer.
Transport storage:
1. This product is stored in dry, ventilated, cool place, shelf life from the date of production has not been opened for 2 years.
2. Transportation shall be handled as non-dangerous goods.
3. Polyurethane waterproof coating shall be stored in a dry and ventilated warehouse for 2 years.
Matters needing attention:
INSTRUCTION:
1. When paving PVC waterproof rolling material, attention should be paid to the construction environment temperature, and the temperature of rolling material should be above -5ºC. When using the full adhesive method, the temperature of the coil can only be above 5ºC.
2. When laying PVC waterproof rolling material, special parts should be made additional layer.
3, pay attention to the construction protection, the end of the daily construction should be temporary fixed coil, so as not to be blown by the wind.
4, waterproof layer construction should be carried out after the end of the last process, not cross construction. If the equipment needs to be installed on the roof with waterproof rolling material laid, it should be treated as an additional layer at the base of the equipment. If it needs to build a high type house on the waterproof layer, it should be carried out after passing the acceptance of the waterproof layer.
