INSTRUMENTAL POLYMER TECHNOLOGIES, LLC — Environmental Protection Agency SBIR Phase I: The environmental impact of wood coatings has become a pressing issue as the manufacturing

Description

The environmental impact of wood coatings has become a pressing issue as the manufacturing of wooden products such as flooring, cabinetry, furniture and doors is moving back to the United States amidst rising labor costs overseas. For the last thirty years the bulk of these products have been painted in countries with lax environmental regulations, allowing the use of inexpensive but environmentally hazardous oil-based alkyd coatings.§Wood furniture manufacturers in the United States have focused on using polyurethane coatings with low volatile organic components (VOCs). In fact, this niche portion of the wood furniture coatings market is the largest use for polyurethane coatings. But it is too expensive to be used for the majority of wood furniture manufacturing. It’s also based on toxic and unsustainable chemistry. Ideal would be a low cost and sustainable, oil-based polymer system which was water based and had not VOCs and which offered the wear and stain resistance of polyurethane coatings. It would help our manufactures compete for the bulk wood products business while also tempting them to replace environmentally toxic polyurethane with a green coatings technology. §Ironically an ideal source for such a low-cost oil-based polymer is nanotechnology. Our company has developed a unique evolution polymerization process to produce high molecular weight dendrimers at low cost and with sustainable raw materials. Dendrimers are spherical polymers which branch out from their center, resulting in a specific core and surface, like a cell. In this project, we will produce high molecular weight dendrimers with a tough and chemically resistant polycarbonate core. Soy methyl ester, otherwise known as common biodiesel, will be attached to dendrimer’s surface to yield a fast drying, low cost, alkyd. Amino acids will be bound in the core to contribute water solubility. Upon cure, the amino acidswill be tucked away in the core of dendrimer so the resulting film id hydrophobic and stain resistant. Methanol produced as the only distillate byproduct will be reused by a biodiesel producer for further production of biodiesel.
