Description of polyurethane waterproof:
SPC-1030 is one-component polyurethane coating with isocyanate, polyether polyol as main raw materials, moisture-curing polyurethane waterproof coating. Especially used for horizontal plane. When this coating is applied on surface substrate, it has chemical reaction with the moisture in the air, and then it will form a seamless elastomeric rubber waterproof membrance.
Characteristics of polyurethane waterproof:
1. Mono-component, available to use when it is opened, easy and quick execution.
2. Stroing tensile strength, high extensibility, excellent high and low temperatures resistance, well adapted to shrinkage, cracking and deformation of coating base.
3. Stroing adhesive force, no need of brushing treatment agent on many coating bases which meet the requirments.
4. Dense film, free from bubbles and holes
5. Film is formed through chemically react, excellent resistance of long-term water erodion, corrosion and mildew
6. Environmentally friendly, no benzene solvent and coal tar ingredients
7. No need to heat, easy to operate
Advantages of polyurethane waterproof:
Good tensile strength and elongation;
Both high and low temperature resistance;
Strong adhesive;
Seamless, no pinholes and bubbles;
Resistance to long-term water erosion;
Corrosion-resisting and mould-resisting;
Convenient to apply.

Application system of polyurethane waterproof:
l.Constructive System
The system is basically consisted of substrate, additional layer, waterproof coated membrane and protection layer.
2.Coverage
Coverage may vary with the substrate condition during application.
SPC-1030 is sealed in 20kg or 25kg pails or 200kg drum and transported on wood plate.
Storage of polyurethane waterproof:
SPC-1030 material should be stored by sealed pails at dry and well-ventilated places and protected
from sun or rain. The temperature in stored places can not be higher than 40° C. It can not be closed to
fire sources. The normal shelf life is 6 months.
Transportation of polyurethane waterproof:
SPC-1030 is needed to be avoided sunshine and rain. Fire sources are forbidden during transportation.
Surface preparation of polyurethane waterproof:
Surfaces should be dry, stable, clean, smooth, without pockmarks or honeycombs and free from any
dusts, oil or loose particles. Cracks and surface irregularities need to be filled by sealants and do additional waterproofing. For smooth and stable surfaces, this step can be skipped.

Since 1999 we entered into EPS business line, we have involved in this industry for more than 12 years. Our company mainly focus on EPS scientific research and development, technical support, and EPS consult information.
In China, we are familiar with domestic developing trends of EPS industry. Here we emphasize on the promotion of EPS raw materials and advanced equipments from abroad, and we help our customers to solve some technical problems during processing, even produce some colored materials for them according to their clients' Demands. We are concerned about EPS raw material prices trends at any time, thus we help our customers save raw material purchasing costs and procurement costs. With many years' Cooperation experience with major shipping companies like MAESK, MSC, COSCO, etc., we ensure our cargoes booking and sailing timely. Through all these efforts so that we can enhance our customers' Competitiveness.
Abroad, we are committed to the promotion of the EPS block machine, packaging machine and automatic cutting line origin from China with Chinese characteristics, high quality & reasonable price. We have erected a bridge for worldwide EPS users engaged in EPS industry to communicate better with each other. Therefore, our customers save a lot of travel costs and time, especially reduce a large number of losses due to quality claims in the disputes with our familiar Chinese laws. We' Re not proud of selling cheap products to our customers, but proud of helping our customers solve purchasing problems.
We also devoted a lot in recycling EPS waste. We gather waste EPS in China, and promise to our customers to recycle waste EPS around the world. We processed these waste EPS into a variety of beautiful and useful products. In this point, we pride for reducing the white pollution, and saving energy for the community.
In China, only a company like us, can engage in areas range from raw materials, equipments and recycling granulations with technical supports, and play endless important role in the whole industrial chain.
Concentrate, so we are professional. You are always our concern centre.
