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.

First, pour the glue on the flat glass to observe its rheology, and wiggle it to observe its rheology,If the flow of glue is too fast, it means that the glue is too thin and poor, and too thick is not conducive to bonding. Secondly, with a hand dip to observe its viscosity if you can slowly draw, a little sticky hand is better. Then, pour it on a small piece of glass to observe its film forming time if it is about 1 to 2 minutes, the film forming time of the glue can form a film on the glue surface is better. The fourth step, the glue after the film is basically solidified with fingers dipped in water to diarrhea, observe its cohesion if the glue is quickly changed to open cohesion is poor after diarrhea glue is turbidified - with filler Finally, stagger the two boards and glue them together. After 24 hours, measure the tension. Soak them for a day and then dry them in the sun to observe the color change Our company produces water based adhesive, welcome to consult
