As we all know, with the development of society, people attach importance to food safety and so on, label printing is greatly encouraged, and label has become comparable to packaging. The development of label has driven the development of label printing, and ink is the main medicine in label printing,In the field of label printing, ink can be generally divided into three categories, namely: water-...
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...
Finally, ordinary glue products, ordinary glue products have a certain elasticity and softness, and have a good tensile length but tensile strength and strength is not very large, adhesion welcome you to consult, this is our email sales@sinogracechem.com
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...
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...
1.After besmear brushes its film sex is good, the surface after coating solidifies can form uniform rubber shape elastomer, and this kind of coating suits special-shaped structure very much. 3.It is very convenient when construction, suit any besmear to brush means, be it wet surface also can construct. 4.Coating itself is absolutely environmental protection, non-toxic without any smell, the use o...
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 ...
◆ 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...
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...
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 ...
