The Difference Between Benzoin And Polyamide Wax In Anti-settling And Anti-sagging

The difference between benzoin and polyamide wax in anti-settling and anti-sagging of coatings is mainly reflected in the following aspects:

1. Mechanism of action

Benzac: Benzac mainly plays a role in increasing the application performance of coatings. By improving the flowability and anti-adhesion of coatings, it makes coatings easier to apply and spread.

Benzac can also form a thin film on the surface of coatings, reduce the solvent evaporation rate, and facilitate the uniform drying of coatings. However, the direct effect of benzoin in anti-settling and anti-sagging is not significant. It is more of an indirect effect on the anti-settling and anti-sagging effect of coatings by improving the overall application performance of coatings.

Polyamide wax: Polyamide wax is a thixotropic additive that can form a strong network structure in the paint system and has strong thixotropic properties. Polyamide wax has strong and continuous anti-sagging and anti-settling properties, has little effect on gloss and weather resistance, and has no or very little precipitation.

Polyamide wax can significantly improve the anti-settling and anti-sagging ability of the coating. Through its thixotropic properties, it reduces the viscosity and improves the fluidity when the coating is subjected to shear force; after the shear force disappears, the viscosity recovers quickly to prevent the coating from sagging.

II. Application scenarios

Benzac: Benzac is more used as a functional additive and flavor additive in coatings. It can increase the application performance of the coating and give the coating a specific flavor. Benzac is a suitable choice in occasions where it is necessary to improve the application performance of the coating, increase the fragrance or create a specific atmosphere.

Polyamide wax: Polyamide wax is mainly used in coatings to improve the anti-settling and anti-sagging ability of the coating. In coatings that require high anti-settling and anti-sagging performance, such as amino baking paint, acrylic baking paint, epoxy baking paint and other baking paints, as well as high-solid coatings, metal coatings, thick paste coatings, etc., polyamide wax is a commonly used additive.

III. Performance characteristics
Benzac: As a natural plant extract, benzoc has certain advantages in environmental protection. However, the performance of benzoc in anti-settling and anti-sagging is relatively weak, and it needs to be used in combination with other additives to achieve the ideal anti-settling and anti-sagging effect.
Polyamide wax: Polyamide wax has excellent thixotropic properties and anti-settling and anti-sagging capabilities. Polyamide wax is highly versatile and can be well compatible with various solvents and resins. The anti-settling and anti-sagging performance of polyamide wax is stable and strong, and it is a commonly used anti-settling and anti-sagging additive in coatings.

In summary, the differences between benzoin and polyamide wax in anti-settling and anti-sagging of coatings are mainly reflected in the action mechanism, application scenarios and performance characteristics. In practical applications, appropriate additives should be selected according to the performance requirements and construction conditions of the coating.
