Technical Details & Test Data

Flex Test Chart

U25 -Unreinforced 25 lb/ft³ (400 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.
