Water-based ink resin is the carrier of pigment in ink, is the core material of ink, its quality, will directly affect the performance of ink, because water-based ink resin to a large extent determines the viscosity of ink, dry fluidity and other properties.Anti - viscosity is an important physical property index of printing ink.Intaglio printing is a kind of printing with high order ink supply, g...
Acrylic pressure sensitive adhesive is a large range, PUR is one of them, most of the acrylic pressure sensitive adhesive is heated operation, can be reheated after bonding, is reversible.And PUR is wet reaction acrylic pressure sensitive adhesive, heating operation, after bonding and moisture in the air reaction, after the reaction is irreversible (that is, heating will not melt). So PUR is more ...
Adhesives with water (inorganic solvent) as the solvent/carrier are called water-based glues, solute (glue) can be dissolved in water/or dispersed in water,Water-based glue can be miscible and dispersed in water, diluent is water. Adhesives with organic solvents as solvents/carriers are called oil-based adhesives (solvent-based adhesives). Oil-based adhesives are not soluble in water and cannot be...
◆ The procedure of bonding process:◆ The adhesive surface should be evenly coated to ensure infiltration, as far as possible to avoid bubbles, due to the porosity of the adhesive strength greatly reduced, resulting in degumming.Attention should be paid to the alignment of the position, not staggered, can be pressurized, air exclusion, make it close contact. Time is three important parameters of cu...
The chemical composition of glue, the polymer in the water environment glue (vinyl acetate in white glue is a kind of petroleum derivatives) are round particles, the radius of the general particle is between 0.5~5μm.The bonding of objects is achieved by the tension between the polymers in the glue.In the glue, water is the carrier of the polymer, and the water carries the polymer slowly into ...
As the composition of waterborne UV curing ink china-africa photosensitivity, pigment and absorb UV light initiator competition, to a great extent, it affected the curing characteristics of the UV curing system in the system Due to the pigments can absorb part of the radiation energy, it will affect the light initiator for the absorption of light, and, in turn, affect the ability to gene...
Composition of pressure sensitive tape 1.Pressure sensitive adhesive, 2.substrate 3.Primer 4.Back treatment agent 5.Isolation paper The main components of the pressure sensitive adhesive and resin, including rubber such as polyacrylic acid ester or polyvinyl ether, homogeneous base material requirements, small scale and good to solvent invasive, including, (1) fabric such as cotton, glass cloth or...
The bonding effect can be achieved by applying pressure for a short time (non-aqueous solvent heating) It overcomes the solvent volatilization and drying time needed during the operation of structural adhesive, and can improve the working environment After stripping, it can be corrected without contamination and can be reused for many times Easy to operate, can greatly improve the production effic...
Waterborne Acrylic Resin Product Description: The water-based acrylic resin is made of acrylic acid and acrylate monomer through solution polymerization. Product purpose: This product can be used for water-based aluminum foil gloss and ink, water-based gravure printing paper gloss and ink, water-based carton ink manufacturing Product features:alcohol water as the main solvent, has no smell, no tox...
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...
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...
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...
Sixteen common types of self-adhesive labels This paper introduces sixteen types of self-adhesive labels commonly seen in daily life. The specific types of self-adhesive labels are as follows： 1. Press smooth writing paper and offset paper labels Multi-purpose label paper for information labels, bar code printing labels, especially suitable for high speed laser printing, also suitable fo...
Label is used to show the relevant instructions of the product of the printed matter, some are on the back of the glue, but there are some printed matter is not with glue, glue label is known as "self-adhesive label". Self-adhesive label is a kind of material, also called self-adhesive material. It is a composite material made of paper, film or other special materials, coated with adhesive on...
Water-based glue, when the autumn and winter season, special attention should be paid to anti-freezing treatment, according to different temperatures, the implementation of different solutions. Cautions (1) Pay attention to warmth and anti-freezing when transporting glue: when transporting below 0℃, pay attention to the warmth of the vehicle, and transport below -5℃ is prohibited; (2) Ke...
Bond strength and deinking Bond strength is one of the most important indexes of glue properties. Bond strength refers to the amount of force required when the film and paper are stripped, and this index is often combined with the deinking effect. We first need to understand the principle and structure of paper-plastic composite. If you want to enhance the bonding force, you must consider the...
