Water based adhesive Water-based adhesive refers to the water-soluble polymer dissolved into appropriate concentration of aqueous solution, or insoluble polymer dispersed into micro-particles (emulsion) in water with the help of surfactant in the general term of adhesives;In simple terms, adhesives made of materials that can be dispersed or dissolved in water are aqueous adhesives and are often re...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
Pressure sensitive adhesive (PSA) is a self-adhesive material, only need to apply a small pressure, can form a van der Waals force on the surface of the two objects, and the adhesive is firmly bonded, this pressure sensitive bonding performance is its basic feature, is also different from other adhesives typical characteristics. PSA can be divided into solution type, emulsion type, photocuring typ...
1.Water as a dispersion medium, do not use organic solvents, non-toxic or flammable danger, is environmentally friendly products; 2.Acrylic monomers have many types, containing ester groups, carboxyl groups, hydroxyl groups and other functional groups have strong polarity, it is easy to emulsion copolymerization with other monomers such as vinyl acetate, styrene, vinyl chloride, etc., to make emul...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
The foam problem in water treatment has troubled many people, debuting the initial foam, surfactant foam, impact foam, peroxide foam, circulating water treatment with non-oxidizing fungicide generated foam, etc., so the use of defoamer in water treatment is more common, this article comprehensively introduces the principle, classification, selection and dosage of defoamer! Methods of foam eliminat...
Advantages and disadvantages of the same type of defoamer Organic defoamer such as mineral oils, amides, low alcohols, fatty acids, fatty acid esters and phosphate esters has been studied and applied earlier, belonging to the first generation of defoamer, which has the advantages of easy access to raw materials, high environmental performance and low production cost.The disadvantages are low defoa...
Let's take a look at the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of the aqueous acrylic emulsion contributes to the flow and wettability of the molecular chains on the surface of the substrate, making the coating and the substrate molecules in close contact to achieve high adhesion. 2.The high bearing capacity of the filler can significantly redu...
Defoamer is a substance with low surface tension and high surface activity, which can inhibit and eliminate foam in the liquid, that is to say, defoamer can reduce the surface tension of water, solution, suspension, etc., to prevent foam generation or eliminate the original foam.Long-term defoaming is also known as defoaming, and the length of the defoaming time is the main sign of the quality of ...
With the rapid development of printing and packaging industry, the appearance design of products is becoming more and more high-end. The composite technology used in modern exquisite printing mainly includes: paper printing and plastic film composite and plastic printing and plastic film composite, that is, paper-plastic composite and plastic-plastic composite.As a new type of packaging material, ...
Brand :Sinograce Type: Water base adhesive Appearance：Milky white emulsion with blue light Performance and use:This product is suitable for the coating of BOPP film, PET film and printed color paper (dry coating process). High bonding q degree, large tension compound drying speed, good parallel flow; For gold and silver cardboard, single powder paper bonding q degree, tension q, to avoid the...
Acrylic paint is a fast drying paint made from pigments suspended in acrylic polymer emulsions and plasticizers, silicone oils, defoamizers, stabilizers, metal soaps. Acrylic paint is water-soluble, but becomes resistant to water when dried.Depending on the amount of paint diluted with water, or modified with acrylic gels, media, or pastes, the final acrylic paint can resemble watercolor, gouache,...
Ink resin is the pigment carrier in the ink, is the core material of the ink, its quality is good or bad, will directly affect the performance of the ink, because the connection material to a large extent determines the viscosity of the ink, viscosity, dryness, fluidity and other properties. Color fastness The adhesion between the ink and the substrate mainly includes the chemical bond force ...
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
Anti-viscosity is an important physical property index of printing ink.Gravure printing is a kind of printing method with high ink supply, good reproducibility and fast printing speed. Most of the inks used are solvent-based volatile drying inks.After the ink is transferred to the substrate through the printing plate, it passes through the drying channel, and the organic solvent is quickly volatil...
The resins that can be used for water-based gravure inks are acrylic resin, polyurethane resin, alkyd resin, etc. Each resin has different characteristics and application occasions, and needs to be selected according to the actual situation. First, water-based gravure ink overview Water-based gravure ink is an environmentally friendly ink, compared with traditional ink, its volatility is small, no...
