It is important to consider the effects of chemical exposure to materials in the design stage. Many factors should be evaluated, including chemical type, concentration, duration of exposure, and operating temperature. Enduro Composites should be contacted for material recommendations regarding specific applications and for information on chemical exposures not listed in this guide. Enduro Composites offers Tuff Span panels in two standard resin systems, which provide outstanding corrosion protection for a broadrange of applications. Premium grade isophthalic polyester is recommended for splash and spill chemical exposure and moderate operating temperatures. Having better strength retention at elevated temperatures, vinyl ester is recommended for certain higher temperatures and chemical exposures.
