Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainl...
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...
Waterborne polyurethane fabric coating agent can give the fabric a good soft and plump feel and skin feeling, and the anti-wrinkle, anti-shrinkage, resilience and flexure of the coated fabric have been greatly improved, waterproof waterproof polyurethane fabric coating agent has become the fabric manufacturers and consumers favored object.So how does waterborne polyurethane work as a waterproofing...
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 ...
Color material gives printing rich and colorful colors,Connecting material as the carrier of color, also as a binder to make the color fixed on the substrate surface; Fillers give the ink the appropriate properties, so that the ink to meet the printing process of printing suitability.Ink should have a certain fluidity, and meet the requirements of the nature of various printing processes, can be q...
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...

The use of flocking glue is different from that of ordinary glue. General flocking process can be divided into three kinds: 1. Flocking box, according to the need of flocking products make it the size of the corresponding flocking box, then placed in the flocking box of villi, connected to the power supply, make the flocking box to form a strong magnetic field, when the product from the side wear ...
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...
