Common knowledge of coating: whether the viscosity of epoxy coating is higher

It is suggested that the viscosity of epoxy coating is determined by three factors One is the resin content in the coating, and the solid content will be high if the resin content in the coating is too much, which will directly lead to the increase of its viscosity, which is of course beneficial to the user Second, the relative molecular weight of the epoxy resin is high or low The relative molecular weight of the epoxy resin used for the steel drum special epoxy coating should be about 3750 Within a certain range, the price of the epoxy resin with high and low relative molecular weight is the same The higher the relative molecular weight is, the higher the viscosity of the coating material will be, but the higher the relative molecular weight is, the epoxy group of the epoxy resin will be Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: the viscosity of epoxy coating is determined by three factors One is the resin content in the coating, and the solid content will be high if the resin content in the coating is too much, which will directly lead to the increase of its viscosity, which is of course beneficial to the user Second, the relative molecular weight of the epoxy resin is high or low The relative molecular weight of the epoxy resin used in the steel drum special epoxy coating should be about 3750 Within a certain range, the price of the epoxy resin with high and low relative molecular weight is the same The higher the relative molecular weight, the higher the viscosity of the coating material However, the higher the relative molecular weight, the lower the epoxy content of the epoxy resin The reaction of phenolic resin will be out of proportion, the network structure formed after curing will be defective, and the adhesion and corrosion resistance of the coating will be reduced The third is whether to use thickener in the coating In order to meet the user's view that the coating has a higher degree of cleverness, the use of thickener in the coating has a great negative impact on its curing reaction, greatly reducing the anti-corrosion performance of the epoxy coating Therefore, the special epoxy coating for steel drum is better with high solid content and slightly low viscosity, so as to make the coating thickness of one-time spraying meet the requirements Most of the domestic epoxy coatings are general-purpose, and the requirements for anticorrosion performance are not as strict as steel barrel coatings The quality, proportion and process requirements of epoxy resin, phenolic resin, iron white powder and other raw materials for the real steel barrel special epoxy coating are relatively strict If the coating is completely produced according to the requirements of steel barrel special epoxy coating, its solid content shall be more than 35%, and its viscosity shall be between 32-40s (coating-4 cups) Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
