PURALACT®B3-modified resins significantly reduce viscosity of coating resins, enabling high solid systems

Company to demonstrate innovative performance building block at ECS

Corbion’s PURALACT® B3 is a new, commercially-available, performance building block for the coatings market. It is a unique, renewable, raw material for coating resins with very high purity that enhances resin efficiency and improves coating performance. Corbion Purac will demonstrate the reduced viscosity and other benefits of resins based on PURALACT B3 for both coil- and decorative solvent based coatings at the ECS (European Coatings Show) 2015, in Nuremburg, Germany, between April 21 and 23, 2015.

By incorporating PURALACT B3 into solvent-based systems, the viscosity of resins can be reduced by up to 50% at comparable molecular weight. Formulation of high solid systems by adjusting the solvent content is possible, leading to simultaneous cost savings through reduced solvent use. For example, the amount of solvent required in alkyd resins for decorative coatings can be significantly decreased.  The result is a system with a lower Volatile Organic Compound (VOC) content that enables a shift towards high solid formulations, with reduced costs in the final coating system. Additional resin efficiency parameters include an improved overall reaction yield and a significant reduction in reaction waste water.

The unique properties of PURALACT B3 modified coatings provide additional benefits, such as improved coating performance. For example, in alkyd based decorative coatings, they enhance gloss and its retention, and shorten the drying time. Furthermore, in saturated polyester for coil coatings, the adhesion on metal substrates is strengthened while the hardness-flexibility balance is enhanced. At the same time, environmental footprint is reduced through increased renewable content and a reduced carbon footprint. Corbion Purac’s PURALACT B3 enhances resin efficiency and improves coating performance.
