Bayer Scientists Discuss How Formulation Variables Determine How Topcoats Weather the Storm
Summary
The authors presented “2-Component Polyurethane Topcoats: Formulating Variables Affecting Performance in the Heavy Duty Corrosion Protections Market,” at 4 p.m., Wednesday, Feb. 2, in Room 20.Commercial topcoats and some lab formulas were used to illustrate raw material choices and how weathering performance plays out in both QUV-A and natural Florida exposure scenarios.Sustainability is central to Bayer MaterialScience LLC’s business and is based around the key areas of innovation, product stewardship, excellence in corporate management, social responsibility and respect for the environment.### Tampa, FL, February 03, 2012 --( PR.com )-- The weathering performance of polyurethane topcoats can be altered by changing variables such as pigment-to-binder (P/B) ratio, isocyanates index, resin/polyisocyanate selection, fillers and additives.Two Bayer MaterialScience LLC scientists set out to determine what effect modifying these variables has on the performance of two-component polyurethane topcoats used in corrosion protection applications, such as bridges, marine settings and stadiums.At Society for Protective Coatings (SSPC) Conference 2012, Kurt Best, senior development specialist, and Ed Squiller, technical director, both of Bayer MaterialScience LLC, detailed the findings of a five-year study comparing some key formulating variables influencing weathering performance of aliphatic polyurethane topcoats in QUV-A and Florida exposure.
