Fire retardant coating defoamers effectively deal with foam problems
Fire retardant coatings usually use special chemical formulas, including flame retardants, fillers, adhesives and other ingredients. These formulas can make the coating have good performance, but during the production process of the coating, due to the characteristics of the raw materials or the production process conditions, a large amount of gas is often introduced, resulting in bubbles in the coating. Adding defoaming agents to fire retardant coatings can effectively control the generation of bubbles, reduce the viscosity and surface tension of the coating, prevent the formation of bubbles, and improve the stability of the coating.
The addition of defoaming agents in fire retardant coatings has the following main uses:
1. Control the foam generation of paint: During the preparation process of paint, due to the characteristics of the material or process conditions, a large number of bubbles are often generated, and these bubbles will form foam when the paint is applied to the surface. The surface of the fire retardant coating requires a smooth and even coating to ensure the consistency and effectiveness of the fire retardant performance. Adding defoaming agents can effectively control the generation of bubbles in the paint, reduce foam generation, and achieve better surface quality.
2. Improve the coating’s influence: When the paint forms foam, it will have a negative effect on the coating’s influence. Foam will make the coating surface rough and reduce the adhesion and coverage of the coating, thus affecting the performance of the fire retardant coating. By adding a defoaming agent, the presence of foam can be effectively reduced, the influence and adhesion of the coating can be improved, and the fire retardant coating can form a uniform and tight coating on the surface.
3. Promote the drying and curing of the coating: Foam in the coating will hinder the drying and curing process of the coating. Foam will sink into the pores in the paint, hindering the evaporation of the solvent and the reaction of the curing agent, resulting in a longer curing time of the coating. By adding a defoaming agent, the foam can be destroyed and the coating can be quickly dried and solidified, thereby improving construction efficiency and coating quality.
