Special anti-corrosion coating is a new type of anti-corrosion coating for the inner wall of oil tanks. This coating is a high-solids, thick-build epoxy anti-corrosion coating. The construction on the bottom surface is simple. It only needs to be sprayed once or brushed or rolled twice to achieve the above dry film thickness. The coating has excellent mechanical properties and good chemical stability, and is especially excellent in oil resistance, water resistance (seawater, tap water, distilled water, crude oil sewage), and oil mixed liquid resistance.
It is suitable for internal anti-corrosion protection of storage tanks and transportation pipelines of high-temperature sewage, clean water, crude oil and various oil products. It is especially suitable for occasions where the coating conditions are very harsh and require one-time coating.
, Paint composition and packaging
This paint is a two-component epoxy resin paint, divided into two components: A and B)
Component A (sauce red liquid) Component B ( Brown liquid)
The ratio between the various components of the paint is the optimal dosage ratio obtained through extensive experiments. For convenience of use, the products are packaged in proportion when leaving the factory.

Construction method
&)
Surface treatment
In order to improve the anti-corrosion effect of the paint, you should Remove the remaining paint film, rust, oil stains, oxide scale and debris on the surface of the base material, and sandblast and remove rust to level (B) or manual rust removal to level (B). The cleaned surface should be painted in time to prevent re-rusting.
) Paint preparation
Stir the paint thoroughly before use. After stirring evenly, pour Part B into Part A and mix evenly before use. If the amount of paint is small, components A and B can be prepared in proportion.
&)
Painting
Brushing, roller coating, or spraying can be used. Spraying has the best effect. It is not necessary to add diluent when brushing and roller coating. When spraying, % of 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 every hour under normal temperature conditions.

After each painting, the painting tools should be cleaned with thinner in time , to prepare for next use. If spraying is used, the spray gun and hose should be cleaned with thinner in time after construction to prevent clogging after curing.
, Precautions
) Coatings contain organic solvents. Pay attention to ventilation at the construction site, use explosion-proof lights for lighting, and open flames are strictly prohibited.
) Please store paint in a cool, dry and ventilated place.
