Water-based anti-rust paint is made of water as a dispersion medium, using physical, chemical and other multiple anti-rust mechanisms, according to chemical conversion, network and reaction and other chemical principles, is the best replacement product
Waterborne anti-rust paint is widely used, the following construction points and precautions, in order to better play the effect of anti-rust paint, protection more durable paint online coatingol.
NO.
Stir well -
Water-based anti-rust paint needs to be fully stirred evenly before use, it takes 3 minutes to use an electric stirrer, and it must be re-stirred
NO.
Substrate Treatment——
Sandblasting rust removal or manual grinding, just remove the loose rust on the surface and clean up the dust, if the treatment is not less than Sa2.
NO.
Cleaning equipment——
The spray gun, pipe and drum are to be cleaned, and the airless spray equipment is cleaned with thinner and then rinsed with water with detergent
NO.
Two-component product formulation——
Strictly in accordance with the A+B ratio, the prepared paint is used within the specified time
NO.
Amount of water added——
According to the construction needs, water can be added 0-10% dilution, otherwise it will affect the film-forming and anti-rust effect
of water-based coatings.
NO.
6
It is strictly forbidden to add organic or inorganic solvents——
It is strictly forbidden to incorporate organic and inorganic solvents such as Tianna water, toluene, xylene, gasoline, etc.
, otherwise a chemical reaction will occur, resulting in the destruction of the active ingredients of the
coating.
NO.
7
Construction Conditions——
Maintain ventilation during construction, the optimal temperature of water-based paint construction is above 10 ° C, the air humidity is below 80%, and the workpiece sprayed on rainy days cannot be immediately placed in the outdoor rain, so as not to affect the adhesion and anti-rust function
of the coating.
NO.
8
Painting construction——
In the construction process, if you need to reduce the viscosity, you can add an appropriate amount of clean water to dilute, add water not excessive, the recommended amount of water should be less than 10%, dilute should follow the principle of a small amount of
many times.
Air spraying is recommended to obtain a uniform and good coating film
.
It can also be constructed by roller coating and brush coating method, and the construction interval of each channel is not less than 2 hours
.
