Indonesia leather side oil defoamer solution

Customer type

1. Customer information: Indonesia Tianheng Paint Co., Ltd. specializes in the production of paints. Because the previous defoamers could not solve the problem of the product, I found Nanhui.

2. Sample information: two samples of matte leather edge oil

3. Customer's requirement: Adding defoamer to bright leather edge oil/matte leather edge oil should not contain floating oil or floating matter. Defoaming and suppressing foam should be close to the sample defoaming agent.

Principle and analysis of defoaming

1. Reasons for blistering:

①External factors: During the application of bright leather edge oil/matte leather edge oil, such as air spraying, airless spraying, curtain coating, etc., turbulence, splashing, impact, air pockets, etc. in the paint will be affected to varying degrees Adding the free energy of the coating system makes it easy to produce foam

②Main factor: When adding emulsifier to water-based latex paint, the surface tension of the emulsion system is greatly reduced due to the use of emulsion

2. Foaming hazards:

① The air in the foam hinders the dispersion of pigments or fillers

② Insufficient utilization of equipment affects production quality

③ The foaming is still at the stirring speed, so that the mixing time is prolonged

④ The pigments and fillers cannot be fully wetted

⑤ It also causes dissatisfaction and uneven weight in the continuous filling production line

⑥ There are pits, small holes, etc. on the coating film during use

3. Analysis of the types of defoamers

①Tributyl phosphate is more expensive, has poor foam suppression and cannot be stirred, otherwise it will regenerate foam

② Although the price of n-octanol is low, its ability to break and raise bubbles is poor and contains bad gas, which is harmful to human health.

In this regard, Nanhui developed the CQ-104/105/106 leather edge oil defoamer, which can effectively eliminate the foam produced by the construction of low-viscosity emulsions and emulsifiable concentrates, and its characteristics will not produce shrinkage. It has low dosage and high efficiency. , Strong defoaming durability, good versatility of use, no side effects, and paint brushing properties have reached the effect of well-known foreign brands
