What is the role of defoamers in the production of coatings and inks
The role of defoamers in the production of coatings and inks is crucial, mainly in the following aspects:
Controlling foam: In the production process of coatings and inks, foam is prone to formation when mixing raw materials or stirring. Defoamers can quickly reduce or eliminate these foams, preventing them from interfering with the production process.
Improve product quality: Foam affects the uniformity, stability, and final performance of coatings and inks. The use of defoamers can improve the quality and consistency of the product.
Prevent coating defects: During coating application, foam can cause defects such as pinholes, fisheyes, orange peel, etc. in the coating. Defoamers help to avoid these problems and ensure a smooth and uniform coating.
Improved rheological properties: Defoamers can improve the rheological properties of coatings and inks, making them easier to apply and level during application.
Improve production efficiency: By reducing foam, defoamers can speed up production, improve the efficiency of the production line, and reduce production costs.
Optimized storage stability: Defoamers help improve the stability of coatings and inks during storage, preventing product deterioration or delamination due to foam formation.
Enhance pigment dispersion: In some cases, defoamers can also help improve pigment dispersion in coatings, increasing tinting and hiding power.
Reduced equipment attrition: Foam can increase wear and tear and cleaning costs for equipment. These losses can be reduced by using defoamers.
Improved workability: Defoamers can improve the applicability of coatings and inks, making them smoother when spraying, brushing or rolling, and reducing the generation of air foam.
Meet environmental requirements: Some types of defoamers are water-based, which helps to reduce the use of organic solvents and meet environmental and safety requirements.
Adaptable to different application environments: Depending on the type of coating and ink and the application environment, different types of defoamers can be selected to meet specific performance needs.
