Commonly used alkyd paints include antirust paints , as well as alkyd topcoats, organosilicon alkyd topcoats, styrene modified quick-drying alkyd paints, etc. .
(1) Hongdan alkyd antirust paint Hongdan alkyd antirust paint is a traditional antirust primer with excellent antirust performance. formulated with solvents and organic solvents. Due to rumors about red pill, its application has been restricted now.
(2) Alkyd aluminum powder iron red antirust paint is prepared from pentaerythritol alkyd resin, phenolic resin, aluminum powder, iron red, drier and 200# solvent oil. The paint film dries quickly, is tough and has good adhesion. Compared with alkyd red lead antirust paint, no harmful gas will be produced during welding and cutting.
(3) The micaceous iron alkyd antirust paint is made of long-oil pentaerythritol alkyd resin, mica iron oxide pigment, suitable aluminum powder slurry, drier and 200# solvent gasoline. The paint film has good adhesion, good moisture resistance and weather resistance, and anti-pollution gas erosion. Suitable for use as an intermediate coat in anticorrosion systems for alkyd resin coatings.
(4) Alkyd zinc phosphate/aluminum tripolyphosphate antirust paint is an antirust primer made of alkyd resin as the base material and zinc phosphate or aluminum tripolyphosphate as the antirust pigment. It has good adhesion and no clusters. Strong anti-rust performance, can replace the toxic red lead anti-rust paint, and can also be used as a primer for anti-rust on light metal surfaces.
(5) Styrene-modified quick-drying alkyd paint Styrene-modified alkyd resin can usually be used on decks, walkways and other parts of ships due to its high hardness. Adding anti-slip sand can form anti-slip coating. Due to its quick drying property, the primer can be recoated after 2 hours at 20°C, but not more than 4 hours. Otherwise, it is required to wait for the paint film to fully cure after 2 weeks before recoating.
(6) Alkyd resin topcoat Alkyd resin topcoat is mainly matched with alkyd resin primer. It is used in mild to moderate corrosive environment, in neutral rural environment and dry building interior, etc., and its service life can reach 10~,20 years.
Alkyd topcoats chalk and yellow when exposed to UV light, but this happens much better than epoxy topcoats. Alkyd resins have limited resistance to chemicals and solvents, and are not resistant to water and are not suitable for use in environments that are often exposed to moisture.
The air temperature during the construction and drying process of the alkyd resin topcoat should be kept above s·c C41), otherwise the drying time will be prolonged. However, alkyd topcoats can also be applied down to -5°C (23°C) with a correspondingly longer drying time. Applying too thick a single coat can cause problems such as slow drying and wrinkling. Many users complain that alkyd topcoats dry too slowly, mainly due to overcoating.
It sometimes happens that an alkyd topcoat is applied over an epoxy primer and is best avoided as this can cause adhesion problems. When a one-component topcoat is required, an acrylic topcoat can be used instead, which is superior to alkyd topcoats in all aspects. Alkyd topcoats tend to yellow when exposed to the atmosphere, but are more durable than epoxy topcoats. In environments without natural light, such as bathrooms, alkyd topcoats will gradually turn yellow. The initial gloss and gloss retention of alkyd resin topcoats have a lot to do with the color, usually white is better. The actual gloss has a lot to do with the color, formula, production place, construction method, substrate and exposure environment.
