Polyurethane coating film bright and full, hard wear-resistant, oil, acid, chemical and industrial waste gas resistance, good electrical properties, and a variety of resin miscible, can be adjusted in a wide range of formulations to meet different needs. Widely used in wood, automobile, aircraft, machinery, electrical appliances, instruments, plastics, leather, paper, fabric, petrochemical an...
The method of using silane coupling agent mainly includes pretreatment method and integral blending method. When using silane coupling agent, it is necessary to choose the appropriate method and conditions according to the specific situation. At the same time, it is also necessary to pay attention to the amount and time of use of silane coupling agent to ensure that it can play the best ...
Aqueous acrylic emulsion is a kind of chemical raw material with strong function and excellent performance, which is widely used in many fields such as coating, ink, textile, papermaking and waterproofing. This emulsion is mainly composed of pure acrylic monomer, which is prepared by precise copolymerization, and its non-toxic and pollution-free characteristics make it popular. I.Physica...
(1)Paint for transportation vehicles cars, ships, aircraft and other transportation vehicles, in addition to meet the requirements of gloss, friction resistance, adhesion, etc., due to its special frequency of use and environment, the waterproof performance of waterborne polyurethane coatings used is also put forward high requirements. The water-based polyurethane waterproof coating referred to he...
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...
Aqueous acrylic emulsion High viscosity is a monomer polymerization emulsion with good self-crosslinking performance, which helps to improve the density and water resistance of the film. The high hardness ensures the stability of the coating under external physical impact, and the high solid content increases the covering power of the coating and reduces the number of construction. Alkali resistan...
Gloves are mainly used to protect the skin from harm in People's Daily activities and special environments, and can also be used to play a decorative role in daily life.According to the different production methods, it is divided into knitted gloves, sewing gloves, soaked gloves and so on. Depending on the function, there are flame retardant gloves, welding gloves, non-slip gloves, oil resistant g...
The commonly used resins for waterborne wood paint are polyurethane and acrylic acid. Waterborne polyurethane resin is a wear-resistant resin commonly used in waterborne wood paint, which can form a hard, wear-resistant coating to provide good protection for wood.The commonly used resins for waterborne wood paint are polyurethane and acrylic acid. Waterborne polyurethane resin is a wear-resistant ...
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...
01 Conditions for film formation Stowing operation The water evaporates, and the particles are close to each other to achieve a dense charging state Fusion process The surface layer of the particles is destroyed, and the particles are in contact with each other. Diffusion process The molecular chains between the dispersion particles are diffused with each other to form a homogeneous film with cert...
(1) The use of hydrosol Hydrosol is a polymeric dispersion of very small particles, which has the characteristics of both emulsion system and solution system, and can effectively improve water resistance (2) Reduce the amount of emulsifier Although emulsifier plays an important role in the formation of micelles in polymerization and the stability of the polymerization emulsion, it is als...
As for the performance difference between water-based acrylic acid and water-based polyurethane, it can be briefly analyzed from the following aspects: 1.Chemical structure: Waterborne acrylic resin is mainly composed of acrylic monomer, while waterborne polyurethane resin is composed of isocyanate monomer and polyether or polyester polymer. 2.Performance characteristics: Water-based acrylic resin...
Solid acrylic resins are widely used in the formulation of water-based printing inks. Common water-based printing ink formulations are usually composed of acrylate copolymer emulsion, solid acrylic resin, pigment filler and wetting agent, defoamer, etc. Acrylate copolymer emulsion is the main bonding material, and solid acrylic resin is the pigment dispersant, also known as dispersion resin. Aqueo...
Water-based adhesives for more sustainable bonding Water-based adhesives are an excellent alternative to solvent-based systems because they do not contain any volatile organic compounds (VOCs), are lighter in weight, and generally require less product to form a lasting bond. Compared to other solutions, water-based adhesive systems are environmentally friendly, have low VOC content and are more us...
Acrylic emulsion has been widely used in various fields of coating industry because of its diversity, versatility and weather resistance.Waterborne acrylic emulsion is the emulsion polymerization of vinyl monomer based on acrylic monomer. In the polymerization process, emulsifier, stabilizer, pH regulator and other additives are added, and the system is complicated Sinograce Chemical launched...
