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 changes from hydrophilic to hydrophobic, so as to promote the interface between inorganic matter and organic matter. Coupling agents and surfactants have some similarities in molecular structure and application properties, but there are also differences. Both are composed of hydrophilic and hydrophobic groups.Surfactant through the molecular hydrophilic group oriented adsorption on the surface of inorganic color, packing monolayer, which is a physical adsorption phenomenon, so as to improve the dispersion and wettability of the color and packing in the base material, so it is only physical adsorption, so the surfactant migration phenomenon affects the luster, appearance and adhesion. Coupling agent is through chemical reaction and the surface of inorganic fillers accidentally coupling consolidation and crosslinked polymer binders, combine two kinds of different material, plays a role of bridge, from the bonding strength, raise yan, filler dispersion process in the basic material and reduce the extent of interfacial energy, coupling agent is greatly better than surfactant.

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 is as a result of making lubricious lacquer, if enamel mixes lacquer to wait. Second, in the wood finishing process for the deployment of pigment colorants, used for substrate surface coloring. The third is to use it as physical pigment, used to deploy putty for wood surface inlay and fill holes. Our company produces wood lacquer, welcome to consult

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 Crosslinking conditions :110 5 minutes to bake, set for 24 hours peel strength :> 1.4 KG/inch Adhesion: more than 24 hours PH: 7-9 Shelf life :12 months (stored in dark and cool place) Packing: 50kg/drum Feature 1. Pure acrylic latex, excellent outdoor weather resistance, good light resistance and transparency 2 .Single component, easy to use, environmental protection 3. Has high initial adhesion and adhesion, while taking into account the long-term high temperature environment of good cohesion 4. Excellent anti-transfer performance, transfer without residual glue is an important requirement of PVC OPP base material tape 5.PVC or OPP film as the base material coating conforms to the test, the amount of dry glue is not less than 25 grams per square meter

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 most common printing form is letterpress, and other printing methods are also used.Common faults in the printing stage are: Fault The ink layer on the printed label surface does not dry, dries slowly or the ink layer is wiped off. Cause The printing ink layer is too thick, the amount of ink is too large and the additives used in the ink are not suitable for ink denaturation or the type of ink used is not suitable, which will cause the label ink layer after printing to dry slowly or wipe off the ink layer; In addition, the machine was running too fast and dry Solution Using deep ink thin printing method to reduce the thickness of the ink layer Use fast drying special ink Add the desiccant with the supporting additive Take measures to extend the drying or curing time of printed matter Raise room temperature, appropriate exhaust, speed up ink drying Sinograce chemical produces various kinds of printing ink raw material resin, welcome to consult
