Which Kind of Anti-rust Paint Is Better?

In interior decoration projects, many details require our special attention, such as the question of which paint is better for metal decorative profiles. Because in interior decoration profiles, not all decorative materials are made of stainless steel. If some interior decoration profiles are rusted on the surface due to installation environment, material quality problems, and other reasons, this is a very bad thing. Therefore, for this type of decorative material, we need to use anti-rust paint for protection. Tongcha workers will apply anti-rust paint on the bottom layer of these decorative profiles, and then apply the paint you want on the outer layer so that they will not rust easily while meeting our decoration needs. So, among the many different anti-rust paints, which one is better? What are their characteristics? In this article, let's take a detailed look.

What types of anti-rust paint are there?

1. Red lead epoxy anti-rust paint

Red lead anti-rust paint is a paint made of red lead and drying oil. It has good permeability and wettability, a soft paint film, and strong adhesion, but it dries slowly. In addition, since red lead has a large specific gravity, contains particles, and is easy to precipitate, it will become thicker if stored for too long, and its brush ability is also poor.

Material composition

This anti-rust paint is mainly composed of modified resin, anti-rust pigment, body pigment, desiccant, organic solvent, etc.

Product Features

This anti-rust paint has good adhesion, high anti-rust performance, strong water resistance, and slow natural drying at room temperature.

Product Uses

This anti-rust paint is mainly used for rust prevention of mechanical equipment, steel structures, pipelines, and other equipment.

2. Iron red phenolic anti-rust paint

This is a paint based on phenolic resin and red iron oxide, mainly used for rust prevention of steel.

Material Composition

Phenolic paint is composed of rosin-modified phenolic resin, polyol rosin ester, drying vegetable oil, mica powder, red iron oxide, pigment, desiccant, No. 200 paint solvent oil, or turpentine.

Main Applications

This paint is mainly used for coating steel structure surfaces as a rust-proof primer.

Product Features

This paint has strong adhesion, dries quickly, is cheap, has average anti-rust performance, and has poor weather resistance. It is mainly used as a primer for steel surfaces with low requirements for indoor and outdoor anti-rust. Phenolic enamel and alkyd enamel can be used as topcoats.

3. Alkyd anticorrosion and antirust paint series

The alkyd is an anticorrosion and antirust paint series consisting of alkyd resin, modified resin, antirust pigment, filler, additive, mixed solvent, etc.

Product Composition

This anti-rust paint is composed of alkyd resin, modified resin, anti-rust pigment, filler, additives, and mixed solvent.

Product Features

This series of products is characterized by fast drying speed, good adhesion, and good anti-rust performance. Alkyd red lead anti-rust paint is a passivation anti-rust primer. Alkyd iron red anti-rust primer contains stable anti-rust pigments, which can effectively inhibit rust and transform rust into a beneficial protective layer. Alkyd micaceous iron anti-rust paint has strong anti-penetration ability and good anti-corrosion and anti-rust effects.

Product Application

This series of products are mainly suitable for anti-corrosion and anti-rust primers on the internal and external surfaces of various steel structures, mechanical equipment, vehicles, pipe racks, storage tanks, ships, etc. in natural atmospheres or environments with a slight degree of corrosion. It cannot be used in underwater areas and is not recommended for galvanized steel surfaces. Alkyd iron red anti-rust primer is also suitable for coating metal surfaces with oxidized rust. Alkyd red lead anti-rust paint can be used for anti-corrosion coating of non-ferrous metal surfaces, but cannot be used in environmentally friendly occasions. Alkyd micaceous iron anti-rust paint can also be used as a midcoat.

4. Zinc yellow anti-rust paint

This anti-rust paint is relatively expensive, but its performance is also excellent.

Composition materials

This anti-rust paint is mainly made of pure phenolic paint with zinc chrome yellow pigment added to it.

Product characteristics

It has high salt water resistance.

Product application

Due to its excellent salt water resistance, it is usually used in the shipbuilding industry.

How to choose anti-rust paint?

1. Give priority to suppliers with a good reputation. At the same time, check the production date and shelf life when purchasing, and check whether the packaging is intact and well sealed.

2. Before unpacking, carefully check the product content, whether the main paint surface is crusted, whether the paint liquid is transparent, whether the color is uniform, and whether the fluidity is good. The curing agent should be a water-white or light yellow transparent liquid, without stratification, or condensation, clear and transparent, and free of impurities.
