Technical Details & Test Data

Flex Test Chart

Kayco Composites U20 - Flex Test Chart

U20 -Unreinforced 20 lb/ft3 (320 kg/m3) Material

Tests were performed on a 17" (431.8 mm) long and 1-1/2" (38.1 mm) thick KAY‑CEL samples with the above physical properties.

The chart above shows how Fiberglass reinforcement increases the strength of KAY‑CEL CORE by 300%.

Water Absorption Test

The chart above shows how marine plywood loses 60% of its strength after being submerged for 24 hours

Storage & Handling

Handling Information
  • Store Kay-Cel Core material indoors or protect from sunlight.
  • Can be cut with normal woodworking tools.
  • Wear dust mask, eye protection, and gloves when cutting.
  • Can be use with a wide variety of resins.
  • Do Not burn material.
  • Best practices:
    • Maintain dry, clean surface for maximum bonding.
    • Pre-wet boards with resin before applying fiberglass.
    • Remove any release agensts or shiny spots before bonding.
