The Influence of Coating Defoamers on Temperature, pH Value, and Environment

The precautions for the use of paint defoamer must be understood by everyone who purchases and uses paint defoamer. When using paint defoamer without understanding it, it often has the opposite effect. For example, why can't I remove so much foam when I add so many samples or when it is clear that the defoaming effect is good, but the defoaming effect is not ideal when facing a large amount of foam? So today, the editor will explain to you what precautions should be taken when using defoamers.

Paint defoamers have certain requirements for temperature, pH value, and environment

The temperature directly affects the quality of defoaming, while high or low temperatures can affect the volatilization of defoamers and may also cause emulsion breaking due to high temperatures.

PH value, it is necessary to understand whether the defoamer is acid resistant or alkali resistant.

The environmental conditions must be good, otherwise the defoamer of the coating is prone to adverse effects with the surrounding environment. Before use, conduct a small-scale test and then a pilot test to find the optimal addition amount

The purpose of the pilot test is to see the effect of defoaming, observe whether this paint defoamer is suitable for its own foam problem, and see the dosage and addition amount in the pilot test to avoid waste of raw materials.

After diluting the final coating defoamer, it should be used as soon as possible within the effective time. Over time, the defoaming effect will be poor.
