Solvent-free epoxy anti-corrosion coating is a new type of high-efficiency anti-corrosion coating. It uses epoxy resin as the main film-forming substance and adds anti-rust pigments. And heavy-duty anti-corrosion coatings composed of various fillers. This product has good physical and mechanical properties, excellent oil resistance, water resistance (seawater, tap water, distilled water, crude oil sewage), resistance to oil and water mixtures, chemical resistance, good wear resistance, and can be coated with thick films (one-time coating The thickness can reach about microns). Since its inception, the product has been used in airports and oil depots inside and outside the military for many years, proving its stable and reliable performance. It is suitable for the anti-corrosion protection of the inner walls of various types of finished oil tanks, oil pipelines, sewage irrigation, sewage pipelines and the corrosion protection of various indoor steel structures.

, construction method
) Bottom surface treatment
In order to improve the anti-corrosion effect of the coating, the paint finisher should remove the remaining paint film, rust, oil stains, oxide scale and debris on the surface of the base material.
) The specific requirements are as follows:
Use shot blasting or sand blasting to remove rust, and the quality should reach level (B&).
If manual rust removal is used, the quality should reach grade (B&).
Before painting, oil, dust and other impurities on the surface should be removed. The cleaned steel plate should be painted in time to prevent it from rusting again.
)Paint Mixing
& Paint should be stirred evenly before use. After stirring evenly, pour Part B into Part A and mix evenly. Leave it for ten minutes before use. If the amount of paint is small, components A and B can be prepared in proportion.
) Paint
It can be applied by brush, roller or spray. If dilution is needed, % of special diluent can be added according to the construction temperature to adjust the viscosity. During construction, try to ensure that the coating is evenly thin and thick, without leakage or sagging, and reaches the specified thickness. It can be applied once a day under normal temperature conditions.

After each painting, the paint brushes and other construction tools should be cleaned with thinner in time to prepare Use next time. If spraying is used, it is even more necessary to clean the spray gun and hose with thinner in time to prevent clogging after the paint solidifies.
, Precautions
) The storage period of the paint is . years. If the storage period exceeds the performance index test, it can still be used if it is qualified.
) Coatings contain organic solvents. At the construction site, ventilation should be paid attention to. Open flames are strictly prohibited and anti-riot lights should be used for lighting.
) Please store paint in a cool, ventilated and dry place.
)The construction temperature is above ℃.
