1.Permanent and removable options In terms of the performance of adhesives, they can be divided into two categories: permanent adhesives and removable adhesives.(Permanent is generally used in electronic machinery, such as electronic label, typical: mobile phone battery label, removable is generally used in food, personal care, such as: wet wipes label, fruit label, clothing label, etc.) 2.The surface of the attached object Because labels processed with self-adhesive materials may be labeled on the surface of various materials, such as glass metal cardboard and plastic, and plastic can be further divided into POLYvinyl chloride high density polyethylene.Tests show that different labeling surfaces have the greatest impact on performance (it is best to use glue and materials with the same or similar chemical composition to paste the material). 3.Label the surface structure of the substrate Intuitively speaking, a rough labeling surface requires a strong glue 4.Label the surface shape of the substrate The surface of the base material can be flat or curved. If the surface of the base material has a certain radian (for example, the surface of a medicine bottle with a diameter of less than 3cm), the paper with good adhesion or a strong glue may be required.It is also necessary to choose materials with better flexibility and tensile resistance, such as PVC and flat surface of the pasted material, which can adapt to a wider range of labeling materials. 5.Cleaning condition of label surface Self-adhesive material is most suitable for clean, dry, oil-free and dust-free labeling base material (any labeling, it is necessary to keep the surface of the paste dry, oil-free and dust-free, so as to achieve the best labeling effect) 6.Adverse effect of plastic on glue Adhesive viscosity needs to be pasted under cold, hot, humid or room temperature conditions.Use the environmental sticker label whether it is exposed to the environment below freezing point, whether it is used outdoors under high temperature, humidity or ultraviolet light, and whether it is close to a high temperature car engine.

LHR) Product validation:the water-borne acrylic resin, the aluminum foil light oil and ink transparency is extremely high, the formation of strong metal feeling, colourful, have good adhesion, excellent printing adaptability, good gloss, fast drying speed, molecularly imprinted dry without peculiar smell Product technical information content: formula, manufacturing process, raw material supply list, need equipment list, Formula FAQ maintenance method, raw material inspection and product quality inspection, cost accounting, use method. Water based acrylic polymer emulsions are fully reacted acrylic polymers dispersed in water. These products contain no residual free formaldehyde. These polymers are now being widely used in the paint/coatings, ink, leather, textile and adhesives industries, and are finding their way into other high performance niche applications every day. Our company produces all kinds of Waterborne Acrylic Resin, welcome to consult customers who need Water based Acrylic Resin

Waterborne polyurethane is often used in the preparation of waterborne coatings because of its excellent film formation and adhesion, excellent flexibility and wear resistance.However, water-based polyurethane dispersion contains a lot of surfactant, easy to produce bubbles, and because of the special properties of water-based polyurethane, it is necessary to use the characteristics of water-based polyurethane defoaming agent for defoaming treatment. Application scenarios of waterborne polyurethane defoaming agent When we use waterborne polyurethane coating, by high-speed mixing and construction process of spraying brush and other operations, will cause the bubble; And the viscosity of waterborne polyurethane dispersion is low, usually 0.03-0.1 pa. s, which requires the use of thickening agent, and the use of thickening agent will make the bubble stable and not easy to eliminate.For the bubbles caused by the above factors, not only make the production operation difficult, hinder the dispersion of pigment in waterborne polyurethane, but also make the utilization rate of equipment is insufficient and affect the yield; Moreover, the bubbles left in the film during construction will affect the decorative effect and durability of the coating, so it is particularly important to give full play to the defoaming effect of water-based polyurethane defoaming agent. In order to make waterborne polyurethane defoaming agent play its greater defoaming effect, we should not only know its use method, but also the amount of defoaming agent should pay special attention to, general high viscosity coating, due to defoaming difficulty, foam stability factors, so the amount will be slightly more, generally 0.3-1.0%.And the coating of low viscosity, for example water-soluble coating, as a result of containing the aid dissolvent of certain amount, can reduce dosage appropriately so, it is 0.01-0.2% can commonly.Other water-based coatings or resin coatings, generally about 0.1% at the same time we should pay attention to the amount is not the higher the better, too much will cause shrinkage shrinkage oil and other drawbacks, if the use of silicone defoaming agent dosage is too much, will also affect the recoating coating.Second is the method of adding, most of the water-based polyurethane defoaming agent can not be directly added to the diluted water-based coating, generally added when the viscosity of the coating is high.In addition, it shall be added in two times, once in the abrasive material and once in the film formation, and each stage shall be added in half. Our company produces all kinds of water-based defoaming agent, welcome to consult customers who need defoamer chemical

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 efficiency and product aesthetics Partially replace the traditional screw rivets welding and other mechanical fixation Sinograce chemical produces pressure sensitive glue for all kinds of adhesive tape, welcome to consult.
