Do you know true water-based adhesive defoamer?

Acrylates are widely used in our coatings, adhesives and textile industries. Due to its excellent composition characteristics, in the preparation process according to the ratio of raw materials, processing methods, so it has a variety of different properties and uses, can be used in a variety of industrial fields. However, foam problems in acrylate adhesives are troubling many people, and it is recommended to use water-based adhesive defoamer to remove foam.

Acrylic adhesive is one of the most used areas of acrylic, according to different main materials, chemical additives and application methods, acrylic adhesive can be divided into anaerobic glue, pressure sensitive glue, dry glue, etc., has a wide range of bonding, curing speed, high strength of the adhesive layer, aging resistance and water resistance is also very good, can be applied to a variety of metal and non-metallic materials bonding.

Due to the high viscosity of acrylic adhesive, mixing method is not standard, the air is brought into the glue liquid to form foam, and the viscosity of acrylate is large, the bubble is difficult to eliminate; In addition, due to the production process of adhesive will add a certain proportion of chemical additives, such as thickener, wetting agent, such additives contain surface active substances, with foaming characteristics, will lead to a large number of foam; On the other hand, the adhesive curing speed is too fast, the heat release temperature is too high, the adhesive curing shortening rate is large, and so on will lead to the emergence of foam.

Too much foam will have a bad effect on the performance and quality of the adhesive. First of all, the foam will reduce the adhesive strength of acrylate, resulting in the adhesive layer after curing the item bond is not strong, so that the adhesive quality problems; Excessive foam will affect the production schedule of adhesives, resulting in lower production efficiency and unnecessary costs. These foams are difficult to eliminate, accumulate more, residual in adhesive production equipment, affect the normal operation of equipment, reduce the utilization rate of equipment.

Water-based adhesive defoaming agent has the characteristics of fast defoaming speed and long time of defoaming, which can penetrate into the foam quickly to achieve the purpose of defoaming. In addition, the use of the defoamer will not affect the basic performance and bonding strength of the adhesive, has good chemical stability and a wide range of application, in high temperature and other environments can also play a stable defoamer function.

Smprotectivefilm is also committed to the emulsion pressure sensitive adhesive research and development, production, sales of the company. We can effectively solve the problems that customers encounter in the use of glue because of different production equipment and technology.

We specialize in the production of protective film and pressure sensitive adhesive for many years, with our own R & D team. In the future, through continuous research and development and summing up experience, our glue can be applied to more product application fields.
