Resin is the smallest unit of the three, as a base material in paint and coating formulations, and paint includes paint and has the widest range.
Natural resins are derived from plant-derived resins, such as rosin, amber, shellac, etc. The appearance of pure resins is generally colorless and transparent. In the natural environment, due to the existence of many impurities and the influence of sunlight and air oxidation, the colors are different, most of which are yellowish or dark reddish brown. Natural resins were limited by output and performance, and later gradually gave way to industrially produced synthetic resins. The output of synthetic resin is controllable, the performance is easy to adjust, and the purity is high. With the development of science and technology, there are more and more types of synthetic resin, and its performance is constantly improving.
For example, China Petroleum Resin C9 can be mixed with various drying oils to produce paints, and various resins and pigments can be mixed to produce paints of various colors. Use it to produce paints and are widely used in surface coatings of vehicles, ships, and bridges. . Greatly improve the gloss, hardness, water and alkali resistance of the paint film, and reduce the production cost. The paint mainly uses China C9 Hydrocarbon Petroleum Resin with a high softening point. The addition of petroleum resin to the paint can increase the gloss of the paint and improve the adhesion, hardness, acid and alkali resistance of the paint film.
The application of resin is quite wide, thanks to its good physical and chemical properties. The treated resin has excellent resilience, insulation, water resistance, oil resistance, acid and alkali resistance, pressure resistance, abrasion resistance, high temperature resistance, etc. From the first handicraft to the later application to all aspects of human society. For example, there are umbrellas, gloves, clothes, shoe soles, etc. in the lives of residents. Cars on the road, submarines in the water, planes in the sky, rockets in space... But there are some problems. Some resins are liquid and as rare as water; some are solid and as hard as rocks; and some It is semi-solid and soft, like plasticine. As a result, various problems may arise during storage or use. In addition, when the resin is used alone, a lot of performance cannot be improved, and the performance is greatly reduced. Therefore, some resins have to use liquid organic oil solvents to dissolve them (organic oil solvents are similar to water, both liquids can dissolve certain substances, but water does not contain C molecules, while organic solvents contain C, most of which are Water is incompatible. If mixed together, it will become a discontinuous phase. You can see oil droplets floating in the water.), add some fillers, pigments and other additives as needed to improve tensile strength, bending strength, and resistance High temperature and heat resistance, etc., this becomes paint.
