Acrylic pigment is a dispersion pigment made from polymethyl methacrylate dissolved in mineral spirits. The production process generally includes various polymerization processes, pigment grinding and dispersion processes, and pigment post-treatment processes, which are sometimes difficult to control due to the conditions that require polymerization reactions (such as temperature, pressure, monomer concentration, etc.), and may cause foaming problems and reduce the quality of products.
To do this, we can choose to add the right amount of acrylic pigment defoamer to dynamically eliminate those floating or suspended foams. So,Acrylic pigment defoamerWhat are the important uses and methods of use?Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
First, the importance of acrylic pigment defoamer
By eliminating foam, acrylic pigment defoamers are able to improve the quality of the product, make the coating more uniform and smooth, reduce blemishes and particles, and also improve production efficiency and reduce production costs.
Acrylic pigment defoamer can improve the stability of acrylic pigments, prevent pigments from stratification and precipitation in the production and use process, extend the shelf life of pigments, and prevent pigments from deteriorating during storage.
Second, the use of acrylic pigment defoamer
1.Direct use:In the production process of acrylic pigments, the acrylic pigment defoamer is added directly to the pigment and stirred evenly. This method is suitable for large-scale production and is easy to operate.
2.Mixed use:The acrylic pigment defoamer is premixed with the acrylic pigment before production, followed by stirring and grinding. This method enables the acrylic pigment defoamer to be better dispersed in the pigment and improve the defoaming effect.
3.Dropwise use:In the production process of acrylic pigments, acrylic pigment defoamers are added to the pigments by dropping. This method is suitable for applications where the amount of acrylic pigment defoamer needs to be controlled.
