For the waterproof treatment of metal roof, the requirements are different according to the old and new degree of metal surface. Generally, it is divided into two cases. One is the steel structure building that has been used for more than 2-3 years, and the metal surface of its roof has begun to age and rust. In this case, the waterproof treatment of metal surface shall adopt the process of rust prevention and corrosion prevention first, and then waterproof construction;

The other is the newly-built steel structure building or the building using aluminum plate and galvanized plate as roof plate. The metal surface conditions are very good, and the waterproof construction can be directly carried out after the surface is cleaned and coated with metal surface treatment agent; The traditional and long-standing waterproof products such as waterproof coiled material, resin, silicon copper weather resistant adhesive, polyurethane coating and JS cement-based waterproof coating can not be applied to the waterproof of metal roof for a long time. Facts have proved that it is necessary to deal with the destructive force of metal plate surface caused by temperature change, steel structure vibration, man-made trampling and other factors, We should choose a kind of antirust paint and waterproof material really suitable for metal roof to solve the maintenance problems such as waterproof and antirust of metal roof, rather than isolated and simple waterproof problems.

characteristic:

1. Strong adhesion, good sealing, high and low temperature resistance, fatigue resistance and follow-up performance;

2. Good tensile strength and elongation, strong adaptability to interface deformation and cracking;

3. UV protection, prolonging the service life of the substrate, good aging resistance, weather resistance and corrosion resistance;

4. It has strong acid and alkali resistance, waterproof, flame proof, mildew proof, bacteria proof, algae proof, etc;

5. Large elasticity, suitable for wide areas of - 40 ℃ ~ + 160 ℃, suitable for both north and South;

6. It can be trampled by people, except those with damage. It has a variety of colors and well matches the primary color of metal plate;

7. Water based, single component;

8. Simple construction, good matching with the waterborne metal antirust and anti-corrosion paint, and can be constructed all year round

Metal materials (color steel tile, aluminum, stainless steel, etc.), glass, daylighting tile, aluminum plastic plate, sunshine plate, stone, concrete, etc
