Water-based flexible printing ink is made of water-soluble pigment and water-based additives by a series of process grinding.Flexo water-based ink is suitable for printing various plastic woven bags, plastic handbags, non-woven bags, paper labels, kraft paper bags, corrugated paper, etc.It is non-toxic and odor free, it is not only environmental protection and safety but also can save 30% of the p...
Self-adhesive label Is also called self-adhesive label material. It is a composite material made of paper film or other special materials, coated with adhesive on the back, and coated with silicon protective paper as the base paper.And after printing die - cutting and other processing into finished labels. Self-adhesive materials are usually printed and processed on the label linkage machine. The ...
Water-based adhesive is a one-component pressure sensitive adhesive of self-crosslinking acrylic ester at room temperature. It has adhesion to wood, PVC, metal, glass board and so on. It is suitable for wood skin, OPP tape, double-sided tape, aluminum foil tape and self-adhesive trademark paper. performance index Composition: acrylic polymer Solid composition: 55% 2 Viscosity: 6000 CPS/25 Crosslin...
Pigment is a white or colored fine powder substance which is generally insoluble in water, oil and solvents (some pigments are soluble), but can be evenly dispersed in water.Pigment and film forming material solution mixed on the surface of the material, can form a covering ability of various colors of the paint layer in wood products coating or finishing process, pigment has three functions. It i...
The difference between water-based gravure printing ink and other printing methods mainly lies in: its printing plate through corrosion or engraving, the formation of a lot of plate surface of different volumes of concave hole, known as the ink hole.The ink hole volume is large, the amount of ink filling in the printing process is large, and the ink layer thickness is transferred to the substrate....
Silicone antifoaming agent is a white viscous emulsion.It has been used in various industrial fields since the 1960s, but large-scale and comprehensive rapid development began in the 1980s.As silicone defoaming agent, its application field is also very wide, more and more attention by all walks of life. In chemical industry, papermaking, paint, food, textile, pharmaceutical and other industrial de...
What is a coupling agent? Coupling agent is a class of substances with amphoteric structure, a part of their molecules coupling agent is a class of substances with amphoteric structure, a part of their molecules can be divided into groups and inorganic surface chemical groups reaction, forming chemical bonds; The groups can react with the chemical groups on the inorganic surface to form chemical b...
In the process of coating manufacturing, it is necessary to belong to the hydrophilic polar material Yan, fillers dispersed to belong to the hydrophobic non-polar material organic base material.In order to increase the affinity between inorganic matter and organic polymer, it is generally necessary to use coupling agent or other surfactants to treat the surface of inorganic matter, so that it chan...
The peeling protective coating is a liquid protective coating made of waterborne polyurethane, which can be sprayed on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating.It has good formativity, can in complex shape surface to form a layer of continuous, uniform stick, strength, transparent protective coating, no need baking, room tempe...
Coupling agent is a kind of material with two different properties of functional groups, the biggest characteristic of its molecular structure is that the molecule contains two groups with different chemical properties, one is an inorganic group, easy to react with the inorganic surface; The other is an organophile group, which can react with synthetic resins or other polymers or form hydroge...
Water-based adhesives have various kinds and different properties, which can adapt to the trend of environmental protection. The important properties of water-based adhesive are: solid content (non-volatile mass percentage), viscosity, emulsifier or surfactant total agent dosage, surface tension, pH value, particle size and distribution, film forming temperature, mechanical stability, etc.Com...
Vacuum suction plastic is a kind of waterborne polyurethane adhesive, because it needs vacuum suction plastic machine to vacuum suction plastic so it is called vacuum suction plastic.It is widely used in the vacuum blister thermal composite of visible parts, such as polyvinyl chloride (PVC) and other soft materials and density board, particle board, wood and other vacuum blister molding, main...
Compared with traditional glue, water-based coated glue is made of imported raw materials, with high solid content, low viscosity, good process applicability, strong adhesive force, non-toxic and other advantages are suitable for aluminum foil (OPA), pretreated polyethylene (HDPE,LDPE), polypropylene (OPP, CPP), polyester (PET), polyamide (PA,ONY) film, A two-component solvent-based polyurethane a...
Pressure sensitive adhesive in addition to the adhesive, but also to add adhesive and other auxiliary substances. 1.The adhesive of the pressure sensitive adhesive has rubber or synthetic resin and other materials, its role is to give the adhesive layer enough cohesion strength and adhesion, the dosage is 30%-50%. 2.Viscosifier. Viscosifier rosin and its derivatives, petroleum resin, etc., it...
Now, people's environmental awareness is getting stronger and stronger, and many glue manufacturers are also seeking to transform themselves. Some water-based glue or oil-based glue are produced. Today, we will take water-based glue and oil-based glue as an example to talk about the difference between them. First, the difference between water-based glue and oily glue The first difference is that t...
After the ink is transferred to the printing surface by the blanket at a certain printing speed and under a certain printing pressure, the fixation and drying speed of the ink film, as well as the color, gloss, fastness and resistance after film formation, etc. ensure the printing effect, which are collectively referred to as the printing quality suitability of the ink. It mainly includes color, p...
