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 nonwoven, etc., (2) the plastic films such as PE, PP, PVC and polyester film, (3) the paper such as kraft paper, glass transparent paper and so on, the base material The original degree is between 0.1-0.5mm. The function of primer is to increase the adhesive strength between the adhesive and the base material, so that when the adhesive tape is removed, the adhesive tape will not be separated from the base material and sully the surface, and make the adhesive tape reusable. The commonly used primer is chloroprene rubber partially vulcanized with isocyanate, modified chlorinated rubber. Backside treatment agents are usually prepared from materials such as polyacrylate,PVC, cellulose derivatives or silicone compounds. Can play the role of isolation agent. Double-sided adhesive tape with a layer of isolation paper such as semi-rigid PVC film,PP film or kraft paper. welcome you to consult, this is our email sales@sinogracechem.com

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, adhesionwelcome you to consult, this is our email sales@sinogracechem.com

All kinds of pigments have different absorption rate of light of different wavelengths (transmittance), the absorption rate of pigments is smaller, transmittance is larger, the curing speed of the coating is faster ultraviolet absorption capacity of carbon black is higher, curing is the slowest, white pigment is reflective, also hinder the curing of the general and uv absorption order is: Black>The same pigment ratio concentration is different, the influence of ink film curing rate is different with the increase of the amount of pigment, the curing rate of the ink film has a different process of decline among which the amount of yellow pigment has the greatest influence on the curing rate of the ink film, followed by red pigment green pigment When the amount of pigment is too large, the curing rate of the surface layer of the ink film is fast, but the pigment on the surface absorbs a lot of ULTRAVIOLET light, reduces the transmittance of ultraviolet light, affects the curing of the deep ink film, resulting in the curing of the surface layer of the ink film and the bottom layer is not curing, easy to produce wrinkling phenomenon.

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; Secondly, as a binder, the pigment can be fixed on the substrate surface to achieve the purpose of displaying text, image, marking and decoration. In order to get high quality ink, we must use high quality connecting material.2. Diluent can make the ink thin, increase the fluidity of the ink, while reducing the viscosity of the ink.Remove adhesive, also known as adhesive, it can reduce the viscosity of ink, while not affecting the ink body bone; The purpose of diluent is to dilute the color of ink, also called diluent; Anti-drying agent (antioxidant) can delay the oxidative polymerization process of dry oil; Preservatives can prolong the storage time of water-based ink; Uv absorbers can improve the sun resistance of prints. 3.Pigments and dyes Pigments and dyes are very fine colored substances. Dyes are generally soluble in the binder. Printing ink commonly used for inorganic pigment filler organic dyes and dyes.
