3. Solvent: No
Product features
1.In the water-based systems, the defoaming ability is the strongest in this series of products, and with good dispersion and adaptability.
2.It is especially suitable for defoaming in high solid content, multi-powder system and grinding occasions.
3.High safety, in a reasonable amount of addition will not cause shrinkage and affect the recoating.
Application test
We tested the comprehensive performance of KEPERPOL®-3303W in the grinding color paste occasion,water-based anticorrosive paint and industrial baking paint.
Compare items and methods
1.Defoaming ability when grinding color paste: add 1% defoaming agent when grinding rein-free red paste (F5RK), and compare the amount of foam in the tank after grinding.
2. Shrinkage tendency/Levelling effect: Use color pastes with different defoaming agents to prepare red baking paint. spraying after dilution.Observe the shrinkage phenomenon of wet film and the leveling effect of dry film.
3.Brush coating defoaming ability of multi-powder system: 0.1% defoaming agent was added to the multi-powder water-based anticorrosive paint, compare the amount of foam in the tank after grinding and the defoaming effect after brushing.
Test result
1.Defoaming ability when grinding color paste:It can be seen from the experimental pictures that adding KEPERPOL-3303W has the best defoaming ability when grinding.
2.Shrinkage tendency/Levelling effect:After adding defoaming agents, the wet film did not appear shrinkage phenomenon after spraying, and did not affect the film levelling and gloss after drying.
3.Brush coating defoaming ability of multi-powder system:KEPERPOL®-3303W can play a very good defoaming role in the process of brushing, and has obvious advantages over competitors in construction defoaming.
The test results show that the defoaming power and comprehensive performance of KEPERPOL®-3303W are the best among these products. Please contact us for more information.
