Polynt POLYCOR® 57V Series Gel Coat
Categories: Polymer; Thermoset

Material Notes: Vinyl ester barrier coats 57V have been formulated as barrier coats to reduce osmotic blistering, and as a print blockers, to provide a smoother gelcoat finish. A number benefits have been demonstrated, capitalizing on some of these product’ unique properties.
  • Black color that provides a visual aid to see air bubbles during lamination
  • White available for use behind low-hide colors
  • Less osmotic (water) blistering
  • Improved cosmetics due to reduced fiber print-through & distortion
  • Reduced back side tack
Do not use vinyl ester barrier coats 57V as a finish coat, as exterior durability is poor, and will result in rapid chalking and fading.
