Sporting a Protective Coat with Solvent-Free Solutions
Solvent based polyurethanes have been the work horse technology for the coating industry for the past 50 years. As awareness of the potential health hazards and impact on the environment has grown, pressure from environmental regulatory agencies and consumer protection groups to reduce the use of solvents has increased. As a result, water-based polyurethane dispersions (PUDs) have seen significant growth over the last decade, but this technology is not yet completely free of hazardous solvents.
PUDs have established themselves as the market leading green polyurethane technology in a number of applications such as high quality exterior architectural paint, adhesives, and wood and textile coatings. However, many PUDs still contain some level of solvents. The production of PUDs frequently involves the use of NMP (N-Methyl-2-pyrrolidone) and NEP (N-Ethyl-2-pyrrolidone). Because of the potential health effects involved with the handling of NMP and NEP, there is growing customer and legislative pressure to reduce exposure levels of these solvents and to adopt more environmentally friendly production methods. GEO’s DMPA® Polymeric Polyol HA-0135
has been specially formulated to offer PUD manufacturers a user-friendly and cost-effective alternative to the use of NMP, NEP or other potentially harmful solvents. GEO’s DMPA® Polymeric Polyol HA-0135 is easy to handle and fully compatible with existing manufacturing processes. It can be used to manufacture high-solids, solvent-free, hard and soft PUD formulations suitable for use in a wide variety of applications. Due to its excellent flexibility and water resistance, DMPA® Polyol HA-0135 is especially useful in NMP/NEP-free soft touch coatings for consumer goods, synthetic leather coatings and other sports and leisure equipment coatings. Moreover, the polymeric structure of this product enables PUD producers to use less isocyanate in the final formulation, thereby reducing the overall cost. Solutions. That is our specialty.
