Silicone-Polyurethane coating for anticorrosion

Silicone-Polyurethane coating for anticorrosion  

Product main features

1. High strength of adhesion. The product for polar materials with a strong adhesion, such as steel, cement, wood, concrete, glass and so on.

2. Good corrosion resistance.  Products to acid, alkali, salt and many organic solvents.

3. High temperature resistant performance is good. Long-term stability can resistance to high temperature under 400 ℃.

4. Good surface brightness. In the case of without surface treatment, can also be besmear to brush in the material surface

Light effect, can take advantage of this characteristic often reduce puttying multifarious process such as work.

5. High efficiency to besmear to brush. Anticorrosion besmear again, can reduce the trouble due to multi-layer coating process.

6. Mode of operation is simple, and varied. It can apply a variety of coating process, coating, dipping, roll besmear, brush besmear, etc.

7. The coating density, good protective.

8. Rusty coating. General surface corrosion without treatment, coating can be directly.

9. After completely dry coating non-toxic harmless.

10. Wide application. Can be used for a variety of metal, wood, ceramic, concrete, etc.

Product series and its application

According to the different application areas, products are mainly divided into the following categories:

Metal corrosion, wood preservation, concrete protection class. The following have specific areas of application.

Metal anti-corrosion concrete application: steel structure, all kinds of ships, various chemical tank and pipeline internal and external anti-corrosion, automobile, refrigerator with the color steel plate, the water storage box, shutter corrosion repair, and the iron chain, cast iron tracery wall, garbage trunk, etc.

Wood preservation of specific application: outdoor wooden wooden building, furniture, wooden footway, coastal areas and wood floor coating.

The concrete application of concrete protection: all kinds of used concrete protection and building underground seepage control under the condition of water and so on.
