(Coating Application,Types & Characteristics) New SSPC Paint 47 Fluoropolymer Topcoat Standard for

Since the 1980s, fluoropolymer resin technologies have offered the possibility of a quantum improvement in topcoat decorative properties- gloss and color retention- compared to conventional acrylic and polyester resins. Specifiers of both protective and architectural restoration coatings systems have expressed a need for a new SSPC standard for field-applied fluoropolymer topcoats, particularly for bright and saturated colors.

Since the 1980s, fluoropolymer resin technologies have offered the possibility of a quantum improvement in topcoat decorative properties- gloss and color retention- compared to conventional acrylic and polyester resins. Specifiers of both protective and architectural restoration coatings systems have expressed a need for a new SSPC standard for field-applied fluoropolymer topcoats, particularly for bright and saturated colors. In the past few years, the SSPC C.1.8 committee worked to develop such a standard, which issued in December 2020 as SSPC Paint 471. A key challenge has been to identify a set of accelerated weathering test conditions that would allow for the reliable qualification of fluoropolymer topcoat formulations, much faster than the 10-50 year outdoor service life of the fluoropolymer paint. Using a round-robin weathering study of 13 resin systems (fluorinated and non-fluorinated) from 10 different manufacturers, in four reference colors, we have identified accelerated test conditions that accurately differentiate between high weatherability fluoropolymer formulations, and conventional SSPC Paint 36 and MPI 311 formulations (Spearman rank correlation > 0.90). :
