Industrial anti-corrosion paint is one of the most commonly used anti-corrosion coatings, with alkyd resin being the most extensively employed resin system. Selecting the appropriate alkyd resin to pair with aluminum paste can pose certain challenges. To assist our customers in making the right choice, Silver Rocket Aluminum Paste offers the following advice:

For non-floating aluminum paste, most alkyd resins are suitable. Although the non-floating type has lower gloss, choosing a resin with higher gloss can enhance the final metal paint effect, ensuring that the characteristics of the aluminum paste are adequately displayed. For air-dry paints, it is recommended to use resins with low hydroxyl values to speed up the drying process; for baked paints, resins with higher hydroxyl values can be chosen. Non-floating aluminum paste is not very sensitive to acid values, hence it has broader applicability.

Floating aluminum paste is highly sensitive to the acid value of resins, which can trigger chemical reactions that cause the coating to lose its luster. Generally, when selecting alkyd resins for floating aluminum paste, the acid value should be below 4.0. Although such products are slightly more expensive, this choice is necessary to achieve a high-gloss effect. Compared to non-floating types, floating aluminum paste offers superior reflectivity and thermal insulation properties.

As aluminum paste is a delicate pigment requiring professional application methods, various issues may arise during its use. At Silver Rocket, we look forward to maintaining communication with our customers to jointly address these challenges and ensure optimal application results.
