In order to adjust the viscosity of the polyurethane adhesive to facilitate the process operation, a solvent is often used in the preparation and use of the polyurethane adhesive. Through the dilution of the solvent, the adhesive can be better coated on the composite film. Most of the current polyur... read more
Waterborne polyurethane (PU) dispersions or emulsions are replacing solvent-based products in coatings, adhesives and inks. Nonetheless, pure waterborne PU dispersions have certain inherent defects. In order to obtain stable waterborne dispersions, hydrophilic groups such as carboxyl, sulfonic acid,... read more
Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and pollution, and thus have become the main direction of the current development of the coatings industry. Water-based acr... read more
Factors affecting the drying of water-based acrylic resin: 1. Selection of resin: Aqueous emulsion is a two-phase system. With the evaporation of water, the viscosity of the system does not change much at first, but when the volume of emulsion particles accounts for a critical value of the total sy... read more
In the current society, some vague concepts have appeared, and water-based resins are generally referred to as water-soluble resins. In fact, water-based resins can be divided into water-emulsion type, water-dispersed type and water-soluble type according to their appearance. Many people think that ... read more
