<p>In the field of aqueous-based polyurethanes, POLYURETHANE DISPERSIONS, that complete the chain of Manufacturing the PUDs, from the designing and synthesis of the backbone polyol, to the finished product customized for end use application. We are focused on serving our customers, with a close partnership and delivering world class products. </p><p><br></p><p>This <a href="https://www.chinasinograce.com/water-based-adhesive" rel="noopener noreferrer" target="_blank"><strong>water based solution coatings</strong></a> comprise specialty products ranging from soft to hard, from anionic to cationic, from normal to highly resistant to hydrolysis, from soft to scratch-resistant, from hydrophobic to hydrophilic, from non-swelling to breathable PU polyurethane dispersion a tough balancing act today for coating formulators and end users. Increasingly stringent environmental regulations call for low-VOC products, but one still has to meet the technical requirements for the coating for a variety of substrates. <a href="https://www.chinasinograce.com/polyurethane-emulsion" rel="noopener noreferrer" target="_blank"><strong>Polyurethane dispersions</strong></a> water borne based coatings are an alternative approach to producing polyurethane coatings and adhesives that are low in VOCs.</p><p><br></p><p>PUDS are used in a variety of technical and industrial applications, such as Industrial/Auto and Decorative coatings, wood coatings, leather and PVC leather, adhesives, inks, plastic etc. These products have an ever growing and vast sphere of application. Our products are constantly analyzed and updated to optimize and enhance polymer properties for specific applications, ranging from abrasion resistance to softness of hand. Please find your industry sector and select from the Sinograce Chemical product range the chemicals we can supply. </p><p><br></p><p><strong>What makes water borne based polyurethane dispersion coatings so unique?</strong></p><p>low solvent content (or in many cases solvent-free). </p><p>low odour.</p><p>low viscosity at high molecular weights.</p><p>many options for one component (1K) applications.</p><p>low temperature drying.</p><p>excellent polyurethane performance.</p><p>superior adhesion to a wide variety of substrates.</p><p><br></p><p><strong>ADVANTAGES OF OUR PRODUCTS</strong></p><p>EMULSION CONTAINS SURFACTANTS WHEREAS PUDS DO NOT CONTAIN SURFACTANTS. HENCE, THE WATER SENSITIVITY OF EMULSIONS IS HIGHER THAN DISPERSIONS.</p><p>IT’S A TOUGH BALANCING ACT TODAY FOR COATING FORMULATORS AND END USERS.
