Waterborne Coatings Market
occurs when water molecules penetrate inside, disrupting the attractive force between the substrate and coating.
of coatings can be attributed to expansion due to swelling, gas inclusion, and osmotic processes.
occurs when the coating has:
Good continuous film formation is critical. (without addition of cosolvents)
Good continuous film formation is critical. (without addition of surface modifying additives)
Emulsion when dried needs to be non conductive in nature.
Unlike traditional solvent based polyurethane coatings, PUDs provide a more environmentally friendly alternative with low volatile organic compound emissions and reduced health hazards.
exane HD-1346 is a film forming, aliphatic polyester based polyurethane dispersion, which provides an optimal balance between hardness and flexibility. It is used for formulating high performance metal coatings coatings with good gloss, protection, hardness and durability. Texane HD-1346 is compatible with crosslinking agents such as carbodiimides, aziridines, and isocyanates.
