Why do latex paint defoamers need to be added to latex paint?

  When selecting emulsion paint, if we do not pay attention to whether there are bubbles in the emulsion paint, then various foam problems may occur in the subsequent construction process, such as foaming, peeling, etc. To avoid these issues, it is necessary to add a defoamer for latex paint to eliminate bubbles in the paint.

  As is well known, the main function of latex paint is for the decoration and finishing of internal and external walls. Therefore, our excellent latex paint has a rich and diverse color range, a delicate and smooth feel, and is moisture-resistant and beautiful. It is an excellent decorative coating. Common latex paint formulations contain styrene acrylic, titanium dioxide, lightweight nano calcium carbonate, dispersants, wetting agents, thickeners, film forming aids, mold inhibitors, and water, but these components do not contain defoamers.

  Therefore, when latex paint is used, there will be foam problems. Firstly, analysis should be conducted from the perspective of composition to determine whether there are defoamers present and whether the defoamers present are of inferior quality. If the ingredients do not contain defoamers, bubbles will inevitably appear when mechanically stirring the latex paint. Decorators use this latex paint to paint the walls, and bubbles will be carried onto the walls. After the latex paint dries, the coating will expand and bubbles will fall off, making the coating effect of the wall very poor.

  When purchasing latex paint, it is important to observe the details of whether the paint will blister, in order to avoid the problem of blistering after using low-quality latex paint. If you need latex paint defoamer, you can try latex paint defoamer. Emulsion paint defoamers can effectively eliminate bubbles in latex paint without affecting its original performance.

  The main uses of defoamer for emulsion paint are: water-based wood paint, high gloss transparent finish varnish, floor paint, color paint, finish paint, varnish, spray paint, low viscosity paint, water-borne polyurethane lotion, water-borne polyurethane wood paint, and other systems with high compatibility requirements.

  Product characteristics of emulsion paint defoamer:

  1. Excellent effect on micro foam;

  2. Low dosage, fast defoaming, long foam suppression time, good water solubility, and no oil stains;

  3. It will not affect the film-forming properties and will not cause problems such as shrinkage and fish eyes.

  The use method of emulsion paint defoamer: use directly without dilution; It is recommended to add in sections, which can be proportionally added according to the on-site use effect.

  Suggested dosage: 1/1000 to 2/1000, the standard dosage is determined by the customer based on the specific test situation. If this product is diluted, it should be used immediately. It is best to use it when an angel has used it, and the dilution ratio can be 1-10 times.
