The main agent of anti-fingerprint oil is polymer elastic nano anti-fingerprint film-forming resin, which is the film-forming substance of anti-fingerprint oil. It affects and supports various deep physical properties and polishing quality of the film, such as luster, adhesion, dryness and hardness. The price of anti-fingerprint oily coatings on the market is uneven, because the performance is quite different, so the cost of choosing domestic ordinary resin is far lower than that of imported resin. Similarly, there is a big gap in brightness, hardness, salt spray resistance, acid and alkali resistance, anti-fingerprint effect and so on. Our company pays attention to the production experience of anti-fingerprint oil for many years, and the products are constantly upgraded. In the application of anti-fingerprint oil, the problems of product strength, hardness, bending, scratch resistance, solvent resistance, aging resistance, blister resistance and cooking resistance were solved, and the final comprehensive performance of the product was achieved.

2. Additives: Additives are used to improve the physical and chemical properties and processing characteristics of water-based fingerprint oil. The types of additives are: water-based curing agent, which can improve the film-forming ability of water-based main agent, improve the adhesive strength of coating film, reduce the surface tension of water-based solvent and improve leveling property. It can control the foaming of polishing agent for a long time and eliminate quality defects such as fisheye and pinhole. Improve the drying speed of water-based varnish and improve the printability of paper; Tackifier. It can improve the adhesion between film-forming substance and substrate, improve the dispersibility of main agent, prevent pollution and improve wear resistance; Other additives are plasticizers, which can improve the folding resistance; The selection of additives for high-performance fingerprint oil coatings is also very high, and repeated experiments are needed to determine the compatibility between the main agent and additives.

Third, solvent: the main solvent of water-based anti-fingerprint oil, the volatility of water is almost zero, its leveling performance is very good, there is no irritating smell, it is environmentally friendly, safe, non-flammable and non-explosive. The main function of environmental-friendly water-based solvent is to disperse or dissolve synthetic resin and various additives.
