On January 26, 2022, SINOGRACE Chemical Co., Ltd. will hold the year-end summary meeting and annual convention, and wish everyone a happy New Year.
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 ...
◆ 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...
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...
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 effic...
Silicone antifoaming agent is a white viscous emulsion.It has been used in various industrial fields since the 1960s, but large-scale and comprehensive rapid development began in the 1980s.As silicone defoaming agent, its application field is also very wide, more and more attention by all walks of life. In chemical industry, papermaking, paint, food, textile, pharmaceutical and other industrial de...
Water-based glue, when the autumn and winter season, special attention should be paid to anti-freezing treatment, according to different temperatures, the implementation of different solutions. Cautions (1) Pay attention to warmth and anti-freezing when transporting glue: when transporting below 0℃, pay attention to the warmth of the vehicle, and transport below -5℃ is prohibited; (2) Ke...
Protective film glue transfer, there are a variety of factors, I believe that in the work, many teachers will also encounter a similar situation.The phenomenon of the so-called glue transfer is uneven coating or in the process of transportation, the glue shift remains on the surface of the profile, commonly known as glue transfer. Protective film glue transfer can be divided into the followin...
During December 10, 2022, customers from Russia have come to visit our company. Foreign trade manager and relevant personnel warmly welcome our customers, and introduced our product which they are interested in detailedly. Water based glue
Classification and characteristics of screen-printable pressure sensitive adhesives I.Characteristics and performance requirements of screen printing process Screen printing is through a certain pressure to make the printing base material through the holes of the plate to the substrate, the formation of an image or text. In order to achieve good printing adaptability, the physical properties of sc...
Classification and characteristics of screen-printable pressure sensitive adhesives Ⅱ Classification of screen-printable pressure sensitive adhesives Because of the simple screen printing equipment, convenient operation, simple printing, plate making and low cost, for the application of coating pressure sensitive adhesive, also often consider the use of screen printing process to coating.The ...
Screen printing UV pressure sensitive adhesive and screen printing water-based pressure sensitive adhesive, has the following different characteristics: because UV curable pressure sensitive adhesive does not contain water or organic solvent, so it can be cured without heating drying channel, and water-based pressure sensitive adhesive to water as diluent, need a lot of heat to volatilizing water;...
Water based polyurethane is a kind of block copolymer containing soft segment and hard segment. The soft segment is composed of oligomer polyols, and the hard segment is composed of polyisocyanate and chain extender. It has excellent wear resistance, oil resistance, low temperature resistance, aging resistance and chemical resistance.At present, the water based polyurethane emulsion on the market ...
Together to understand the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of water-based acrylic emulsion contributes to the flow and wettability of molecular chains on the substrate surface, making the coating and substrate molecules in close contact, to achieve high adhesion 2.High load-bearing capacity of the makeup filler can significantly reduce th...
Preparation method of waterborne acrylic emulsion 1.The preparation of water-based acrylic emulsion: the raw materials including acrylic hard monomer, acrylic soft monomer and acrylic functional monomer all acrylic monomer, emulsifier, water added to the pre-emulsifying kettle, emulsifying 30 ~ 40min.A non-stratified emulsion is obtained. Then the remaining water, remaining emulsifier and buffer a...
1.Excellent adhesion The polymer structure of water-based acrylic emulsion contributes to the flow and wettability of molecular chains on the substrate surface, making the coating and substrate molecules in close contact, to achieve high adhesion. 2.High load-bearing capacity of the makeup filler can significantly reduce the cost Waterborne acrylic emulsion has excellent fillability, the total sol...
