Arkema Inc. Provides Guidelines to Estimate Topcoat Color Fade

Arkema Inc. presented recommended guidelines for estimating the color fade of PVDF-based topcoats for bright color architectural restoration and protective coating applications at the SSPC 2017 Conference in Tampa, Fla.

This year’s SSPC Conference served as an international forum at which contractors, consultants, inspectors, engineers, paint/equipment manufacturers and structure/facility owners exchanged research and technologies in the coatings industry. The event’s GreenCOAT technical program emphasized innovations, the latest advances in eco-conscious coating technology and developments for complying with green regulations.

Many common topcoat standards used for architectural and protective coating applications include a durability requirement based on the accelerated weathering performance of a white coating. However, there are currently no standards for field-applied coatings that address the needs of specifiers who want to ensure color performance in high-chroma (saturated or bright) colors.
 
Dr. Kurt Wood, a principal scientist in Arkema’s Fluoropolymers R&D Division, reviewed data for coatings made using a range of pigment chemistries, enabling estimates of color lifetime to be made for virtually any color, if one stays within the particular resin chemistry space. These principles were demonstrated with PVDF-based topcoats, where it was found that both the pigment grades and the resin are important factors for determining the color lifetime, along with the pigment volume concentration.   

PVC Resembles Metal Roofing

SOPREMA Inc. has developed SENTINEL PVC, a high-performance roof membrane that is manufactured using processes that provide rooftop performance, including SOPREMA’s Acrylic Shield surfacing. SENTINEL integrates silver and copper metallic powder in its Silver Art and Copper Art products, providing enhanced aesthetic appearance and weathering capabilities that are identical to metal roofs. The PVC is chemical-resistant, making it well suited for buildings that are prone to grease and oil exposure or factories with exhausts on the roof. SENTINEL PVC is also fire- and wind-rated by Underwriters Laboratories and FM Approvals.
