Applications of Polyurethane-based Coatings

Share this:
Published: 17 Feb 2017

Polyurethane (PU) coatings are widely used across all industries as they have the ability to impart properties such as high durability, toughness, high gloss, and so on. These coatings contain PU resins that are usually formed by the reaction of a polyalcohol with an organic di-isocyanate. However, solvent-based polyurethane coatings are harmful for the environment as they release toxic volatile organic compounds (VOCs). For this reason, water-based polyurethane as well as 100% solids polyurethane coatings are being developed. Stakeholders are also trying to eliminate the use of isocyanates in the production process without sacrificing the key properties of polyurethane coatings. The Advanced Coating & Surface Technology TechVision Opportunity Engine (TOE) provides intelligence on technologies, products, processes, applications and strategic insights on various coatings across industries. This encompasses protective and functional coatings such as antimicrobial coatings, food coatings, energy-saving coatings, smart glazing, hydrophilic, hydrophobic and super hydrophobic coatings, corrosion protection coatings, barrier coatings and paints. The Chemicals and Advanced Materials cluster tracks research & innovation trends and developments across specialty chemicals, plastics, polymers, chemicals, bio-chemicals, metals, coatings, thin films, surface treatments, composites, alloys, oil and gas, fuel additives, fibers and several other related technologies and its impact and application across industries.
