The hardness and softness of the water-based acrylic resin can be adjusted according to specific needs, but it is usually biased towards the harder side. First, the characteristics and application of water-based acrylic resin Water-based acrylic resin is an environmentally friendly water-based resin, with non-toxic, easy to clean, dry fast and other characteristics, widely used in furniture, packa...
Most coatings are composed of a base material (one or more resin mixtures), pigments (including physical pigments and functional pigments), solvents and some small amounts of additives and other coating raw materials. In the production of coatings, after the selection of various coating raw materials necessary for coating components, the next is how to make reasonable use of the technical and econ...
There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice ...
Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coat...
First, resin reaction temperature standard The reaction temperature of resin is an important process parameter, which has great influence on the reaction rate, physical properties and chemical stability of resin. In general, the resin reaction temperature should be determined according to different resin types and catalyst types. The following are some commonly used resin reaction temperature stan...
1.Type: There are three main types of water-based acrylic resins, including emulsion, water dispersion and aqueous solution. The emulsion is synthesized by emulsifying olefins in water under the action of water-based free radical initiator. The aqueous dispersion is synthesized by free radical solution polymerization or stepwise solution polymerization. Aqueous acrylics are directly soluble in wat...
Water-based coatings, acrylic resins are commonly used resins that can not be avoided, commonly used metal coatings, ABS, PC coatings, glass coatings that require hardness, most of them will be applied to acrylic resins, especially solid acrylic resins. There are many varieties of solid acrylic resins, and some solid acrylic resins can be used to produce water-based paints, including the popular l...
Fabric coating finishing is to evenly coat a layer of molecular film on the surface of the fabric to give the fabric with various functions and expand the use of the fabric. Compared with other coating materials, polyurethane coating has high tensile strength, large elongation, good elasticity, good wear resistance, heat resistance, low temperature resistance and aging resistance, and is a hi...
What is Water-based acrylic Emulsion? How is water-based acrylic emulsion classified? Water-based acrylic emulsion is a type of emulsion that is produced by emulsion polymerization, in which various monomers of acrylic acid are polymerized. This emulsion is widely used in the coatings, adhesives, paper, and textile industries. The production process can be simply described as follows: First, mix p...
Water-based acrylic resin and water-based acrylic emulsion have the following differences: 1.Appearance: • Water based acrylic resin: available in a variety of forms, both solid and liquid. Solid water-based acrylic resin is powder, need to be diluted with water after use; Liquid water-based acrylic resin can be transparent or milky liquid, its particle size is relatively small, generally in a nan...
Liquid end hydroxyl polybutadiene rubber (HTPB) is a liquid rubber with hydroxyl functional group at the end of the molecular chain of polybutadiene, which is colorless or light yellow transparent liquid at room temperature. HTPB and chain extender, polyisocyanate cross-linking agent in the reaction at room temperature or high temperature can generate three-dimensional network structure of the sol...
Glove PU coating refers to coating the outer layer of gloves with a layer of polyurethane (PU) material. This coating has a variety of functions, mainly including: Oil and chemical resistance: makes the gloves suitable for work environments where oils and chemicals need to be handled. Anti-slip and wear resistance: Enhances the stability of the gloves in wet or greasy environments, reduces the ris...
Water-based viscosification emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the adhesion strength and initial viscosity of pressure sensitive adhesive on high and low energy surface, so as to achieve the best balance point, and improve the application range and grade of pressure sensitive products. Today, I will introduce you to the applic...
Particle size and hydrolysis resistance: The stability of the emulsion is closely related to the particle size and hydrolysis resistance of the polyurethane particles. The smaller the particle size, the better the stability of the emulsion. The poor hydrolysis resistance will cause the emulsion to degrade slowly during the storage process, produce carboxyl group, reduce pH value, and make the emul...
