Formulating wood coatings can be challenging, given the variety of resins available and the diverse applications in the industry. The key to finding the optimal one-component (1K) waterborne (WB) polyurethane resin for a wood coating application requires a thorough understanding of two factors: the properties of the resin itself and the critical criteria for the particular end-use market. These two factors are inextricably linked and, as such, they must be considered together – not independently – in order to best solve this dilemma.
Bayer MaterialScience LLC researchers have categorized the company’s 1K WB polyurethane technologies as well as the key performance properties for different applications, to provide formulators with an overview of the resins and their applicability to specific wood coating applications. This article presents an overview of the findings, which are designed to help streamline the resin selection process for wood coatings.
