Coatings and inks
Coating is a material that can be applied on the surface of objects, and can bond well with it and form a complete and strong protective film. It has many functions like protection, decoration and other special applications. Based on the form of coatings, it can be divided into water-based coatings, solvent-based coatings, powder coatings, high-solid coatings (including light-curing coatings), etc. Ink, which is composed of binders (resins), pigments, fillers, additives and solvents, etc., can express patterns and characters on the substrate by printing or spraying. It is normally used in books, packaging and decoration, architectural decoration and electronic circuit boards. print. According to different printing types, it can be divided into letterpress ink, lithographic ink, gravure ink, and mesh ink. Also, it can be divided into solvent-based ink, water-based ink, light-curable ink based on the form.
Cellulose ether ：Thickening of latex paints; dispersion stabilization of emulsion polymerization
In the coating industry, cellulose ether is employed as a protective colloid, which can be used for vinyl acetate emulsion polymerization to improve the stability of the polymerization system in a wide pH range; in the manufacture of fine chemicals or products, additives such as pigments and fillers are used, cellulose ether can make them uniformly dispersed with stabilization and enhancement. It can also be used as a dispersant for styrene, acrylate, propylene and other suspended polymers to obtain latex paints with high thickening and excellent leveling properties.
High thickening performance
Excellent water retention
light curing material：Reactive diluent; crosslinking
Energy saving and environmental protection, no VOC
Strong substrate adaptability
Light-curing materials are UV monomers, collectively referred to as UV resins, mostly acrylates. Under the irradiation of ultraviolet light or electron beam, a free radical crosslinking reaction occurs, and the film is cured and formed. Mostly used for UV floor paint, furniture paint, 3C paint, plastic paint, paper varnish, silk screen ink, inkjet.
Alcohol ether solvent：Coating or ink solvent; water-based coating coalescent
High boiling point
Strong dissolving ability
propylene glycol derivatives are called "universal solvents" have excellent performance.Compared with the ethylene glycol dirivative class, they are relatively much healthier, which is increasing sharply in the field of textile, printing, electronic chemicals, dyes, synthetic brake fluids, auxiliaries and cleaning agents. They have good binding properties for all kinds of resin and excellent film formation properties.
Water-based acrylic emulsion; water-based paint wetting agent; raw materials for anionic surfactant
Various non-ionic surfactants are used in the process of water-based acrylic emulsion polymerization to emulsify and stabilize or protect the system. They can also be used as raw materials for various anionic surfactants. At the same time, they can be used as wetting agents in water-based coating formulations to help improve the wetting of coatings with balance of hydrophilic and hydrophobic properties.
Polyether for Polyurethane：Polyurethane architectural waterproofing
Acid and alkali resistance
The polyurethane resin formed by the chemical reaction of polyether and isocyanate acts as a film-forming substance for coatings. Due to the chemical reaction, it is almost free of solvent, has a small volume shrinkage ratio, is easy to construct, has good elasticity and extensibility, and has high tensile strength and tear strength.
