Uses, Types & Advantages of PU Dispersions

Water Based PU Dispersions from Bansal Trading Company

In the field of aqueous-based polyurethanes, [POLYURETHANE DISPERSIONS], we are perhaps the pioneers in India, 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. Made in India. like: Aliphatic Single Pack Self Cross Linking Water Borne Polyurethane Dispersion.

PU Dispersions: This water based solution coatings 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. Polyurethane dispersions water borne based coatings are an alternative approach to producing polyurethane coatings and adhesives that are low in VOCs.

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 Bansal Trading Company product range the chemicals we can supply. Please consult our sales or technical representative for helpful advice.

What makes water-borne-based polyurethane dispersion coatings so unique?

• low solvent content (or in many cases solvent-free). 
• low odour.
• low viscosity at high molecular weights.
• many options for one component (1K) applications.
• low-temperature drying.
• excellent polyurethane performance.
• superior adhesion to a wide variety of substrates.

ADVANTAGES AND U.S.P. OF OUR PRODUCTS

1. EMULSION CONTAINS SURFACTANTS WHEREAS PUDS DO NOT CONTAIN SURFACTANTS. HENCE, THE WATER SENSITIVITY OF EMULSIONS IS HIGHER THAN DISPERSIONS.
2. IT’S A TOUGH BALANCING ACT TODAY FOR COATING FORMULATORS AND END USERS. INCREASINGLY STRINGENT ENVIRONMENTAL REGULATIONS CALL FOR LOW-VOC PRODUCTS, BUT YOU STILL NEED TO MEET THE TECHNICAL REQUIREMENTS FOR THE COATINGS.
3. POLYURETHANE DISPERSIONS ARE AN ALTERNATIVE APPROACH TO PRODUCING POLYURETHANE COATINGS THAT ARE LOW IN VOCS.
