Composite GRP adhesive 25-5 product information

Composite GRP adhesive 25-5 has been specifically designed to bond GRP composite materials within many different industries, such as industrial fiberglass moldings, marine and automotive. The advantage of using reinforced GRP polyurethane adhesive is to speed up the curing and production time when manufacturing GRP moldings. This reinforced GRP polyurethane adhesive will structurally bond gel-coat and fiber side, enabling less work in progress on the shop floor.

How to apply composite GRP adhesive 25-5

Our composite GRP adhesive 25-5 has a working time of 4-6 minutes and a cure time of 12-15 minutes at 20°C. Before dispensing, ensure that surfaces are clean, dry and free of any dirt, dust and grease. For the best results, we recommend using CTA IPA Cleaner Degreaser.

  • Use sufficient pressure over the whole surface at room temperature to ensure maximum adhesion to substrates.
  • The ideal application temperature is between 21 – 40°C.
  • Elevated temperature following application (60°C for 1 hour) improves adhesion wet-out.
  • Primers can increase the bond performance and surface tension. We recommend CTA Primer or CTA UV Identifiable Primer to achieve the best results.
  • Ensure uniform stress distribution.
