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 ...

Polyurethane (PU) is a kind of organic polymeric compounds containing repeated carbamate group (NHCOO) in the main chain.Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, easy processing, low price, but some polyurethane water resistance, heat resistance is poor, need to be modified by specific methods, in order to achieve the purpos...
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...
Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
People often ask, how long can you spray Teflon paint on the mold? How many molds can you take off? To answer the question about the life of Teflon paint, it is necessary to first explain what factors affect the life of Teflon paint. There are three main factors that affect the service life of Teflon coatings. First: coating formula 1.The primer resin content is too low In popular terms, the ...
As for the performance difference between water-based acrylic acid and water-based polyurethane, it can be briefly analyzed from the following aspects: 1.Chemical structure: Waterborne acrylic resin is mainly composed of acrylic monomer, while waterborne polyurethane resin is composed of isocyanate monomer and polyether or polyester polymer. 2.Performance characteristics: Water-based acrylic resin...
Particle size and hydrolysis resistance: The stability of the emulsion is closely related to the particle size and hydrolysis resistance of the polyurethane particles. The smaller the particle size, the better the stability of the emulsion. The poor hydrolysis resistance will cause the emulsion to degrade slowly during the storage process, produce carboxyl group, reduce pH value, and make the emul...
