What are the white pigments commonly used in ink production? Titanium dioxide and lithopone are mainly used. Lithopone is a mixture of barium sulfate and zinc sulfide, containing a small amount of Zn0 impurities, and its molecular formula can be expressed as BaSO4.2Ns. In fact, there is no chemical combination between the constituent compounds in lithopone, and each of them exists independently in...
The solvent used for the connecting material is water first, but pure water (sterile water) is needed. Alcohols are mainly isopropanol, ethanol and so on. Water accounts for the main component, while alcohols only account for 5% to 6% or 20% to 30% of water, depending on the types and properties of resins and pigments. The use of alcohols is mainly to assist water to enhance the ability to dissolv...
In principle, all printed products printed with traditional solvent-based oils can be replaced by water-based inks. Water-based inks have been widely used in the printing of coated paper, white paper, corrugated paper and plastic film, and can be printed by flexographic, gravure, and mesh printing. In the U.S. printing industry ink market, the sales of water-based inks are more than two letters of...
⑴ Not scratch resistant： a. The coating film is too hard: switch to elastic resin; increase the amount of "688", reduce the amount of "BF", and reduce the amount of curing agent. b. The coating film is too soft: the amount of curing agent is not large, or the curing agent is not well stored or the main agent is volatilized, resulting in incomplete curing of the coating film; increase the amount of...

As the global call for environmental protection is increasing, environmental protection materials have begun to be widely used. Many countries have introduced some environmental protection policies, especially in the food packaging industry, which has become more and more stringent, restricting the use of many solvents. All these have brought pressure and motivation to change the ink printing indu...
1）Co-solvent type polyamide resin Recommend solvent: Toluene: IPA=1:1 40% resin: 60% solvent 2) Alcohol Soluble Polyamide Resin Recommend solvent: IPA and Ethyl Alcohol (Customer could adjust the ratio according to their formula. No recommend ratio, as different user will adjust the ratio according to their request about the ink dry speed, compatibility with other resin and pigment, co...
In the process of using adhesives, sometimes the bonding effect may not be good. There are many reasons for this situation, among which the pretreatment of the substrate is a big influence factor. If the surface of the bonded substrate is not clean, it will affect the intermolecular force and cause the paste to be not strong enough. So how should the substrate be treated before using the adhesive?...
Application of high-chlorine CPP and technical limitations CPP with high chlorine content is mainly used in paints and fireproof coatings. Due to the competition of various products such as chlorinated rubber and chloroether, as well as its own technical reasons, it has not formed too many practical applications. So far, the chlorinated polypropylene produced by domestic manufacturers are all prod...
Anti-corrosion coating refers to a type of liquid or solid material that can form a film on the surface of an object under certain conditions to protect, decorate or other special functions, such us, insulation, rust prevention, mildew resistance, heat resistance, etc. One of the chlorine-containing polymers has excellent anti-corrosion properties. A wide range of chlorine-containing polymers is c...
