1. What is the stain to seal the bottom paint?
Answer: The so-called stain-blocking primer is also a primer. Unlike ordinary primers, this primer has permeability to close the concrete pores. At the same time, this primer also has hiding power and can cover the substrate. Stains.
2. The distinction between oil paints and water paints and the distinction between oil paints and water paints?
A: The carrier of the oil-based paint is an organic solvent, such as an alkyd paint and a polyurethane paint, that is, an oil paint. Water-based paint carrier is water, such as commonly used architectural paint latex paint is water-based paint. There is no conceptual difference between oily paints and oil paints. Also, there is no conceptual difference between waterborne and waterborne paints.
3. Why does some paint brush appear to be hard after drying on a glass plate? How much does the hardness and the emulsion content of the film have to do with the type of emulsion?
Answer: In the case of normal film formation, the hardness of the latex paint film has little to do with the emulsion content, depending on the type of emulsion used. If the glass transition temperature of the emulsion used is high, the hardness of the paint film after normal film formation is also high.
4. If you want latex paint to dry faster, what can you do? For example, what kind of additives can be added?
A: Latex paints have no driers. If you want to dry faster, you can increase the volume solids and reduce the use of filming aids and propylene glycol/ethylene glycol in the formulation. Of course, you need to examine whether other related performance is affected too much.
5. Would like to ask how epoxy resin, latex and other products should be dissolved (damaged), without damaging the plastic wrapper?
A: You can try paint strippers that consist of strong solvents.
6. Can you use latex paint on an old house with tiles?
A: The customer plans to use tiles to decorate the interior walls of the living room and apply latex paint on the tiles to change the color and appearance. Recommendation: Because ordinary latex paint has poor adhesion on the tile surface, the key is to first construct a latex paint primer specifically designed for the tile, and then construct the latex topcoat.
7. How to determine the extent of titanium dioxide hiding? What method can be used to detect?
A: The method of determining the contrast ratio can be used to judge the hiding power of titanium dioxide. As for how to determine the contrast ratio, reference can be made to the contrast ratio test method in GB/T9756-2001 Synthetic Resin Emulsion Interior Wall Coating.
8. How to detect the glass transition temperature of an emulsion?
A: The measurement of the glass transition temperature of emulsions is a complex event. Different test methods, the measured glass transition temperature is also different. DSC (Differential Scanning Calorimeter) is the most commonly used instrument for measuring the glass transition temperature. For formulators, the minimum film formation temperature (MFFT) of the emulsion should be taken into account and the minimum film formation temperature can be determined with an MFFT tester.
9. Will the use of Rohm and Haas 3188 emulsion water-based paint, bubble how to eliminate ah?
A: Generally speaking, the use of too strong defoamers, in the case of poor dispersion, prone to defoaming, but there are shrinkage phenomenon. It is recommended to use BKY-024 or other defoamers, and try to increase the dosage slightly.
10. Why does the paint always blisters during construction (even if the substrate is very good)?
A: It may be due to the selection and use of defoamers. If roller coating is used, the quality of the roller can also cause blistering.
