Hogyan m\u0171k\u00f6dnek a szintez\u0151 szerek?<\/strong><\/h1>\n

<\/p>\n

Quick answer:<\/strong> A practical additive decision starts with the exact defect: foam, poor wetting, craters, haze, or instability. The best product is usually the one that solves that defect with the safest compatibility window.<\/p>\n

After the construction of paint, there is a flow and drying film-forming process, and then gradually form a flat, smooth, uniform coating film. Whether the coating film can achieve the characteristics of flat and smooth is called leveling. In the actual construction process of the coating, the film defects that often appear are orange peel, fish-eye, shrinkage, pinhole, shrinkage, Benedict swirl, air sensitivity and due to poor leveling, brush marks when brushing, roller coating roller marks are known as poor leveling, the generation of these phenomena reduces the decorative and protective function of the coating. There are many factors affecting the leveling of coatings, such as solvent volatility gradient and solubility properties, surface tension of coatings, wet film thickness and surface tension gradient, rheology of coatings, construction process and environment, etc., of which the most important factors are the surface tension of coatings, surface tension gradient generated by the wet film in the film-forming process and the surface tension homogenization of the surface layer of the wet film. To improve the leveling of coatings, it is necessary to consider adjusting the formulation and adding suitable additives. In practice, CHLUMILE 3345 Leveling Agent<\/a> \u00e9s CHLUMILE 3033 Leveling Agent<\/a> are often compared so that the coatings have suitable surface tension and the ability to reduce the surface tension gradient.

How buyers usually evaluate coating and ink additives<\/h2>\n

Additive selection is usually most effective when the team defines the defect first and then screens compatibility, dosage range, and process stage. That is often much more reliable than choosing only by chemistry family or by a single dramatic lab result.<\/p>\n
