Applications & Uses

Application Method
Composites Processing Methods
Formulation Guidelines
  • Crystic Gelcoat 76PA FR should be allowed to attain workshop temperature (18°C - 20°C) before use. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy.
  • Crystic Gelcoat 76PA FR requires only the addition of catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or ButanoxM50), which should be added at 2% into the gelcoat. The catalyst should be thoroughly incorporated into the gelcoat, with a low shear mechanical stirrer where possible.
Recommended Applications
  • Crystic Gelcoat 76PA FR can be used for building applications, vehicle bodies and general industrial work.
  • For normal molding, the application of Crystic Gelcoat 76PA FR should be controlled to 0.55 - 0.8mm wet film thickness. As a guide, approximately 750g/m2 of gelcoat mixture (depending on pigment) will give the required thickness when evenly applied.

Regulatory & Compliance

Approvals
  • Properly manufactured, fully cured laminates using Crystic Gelcoat 76PA FR and Crystic 347E PA / Crystic 349E PA achieves a Class 0 / 1 rating to BS476 Part 6 / 7.
  • With the laminating resin Crystic 329E PA, a Class 2 rating can be achieved to BS476 Part 7.

Technical Details & Test Data

Additives

Crystic Gelcoat 76PA FR is supplied in a restricted range of colors. This eliminates the potential for mixing errors with small quantities of pigment paste. The addition of fillers or pigments can adversely affect the weather, fire and water resistance of the cured gelcoat.

Post Curing

Satisfactory laminates for many applications can be made with Crystic Gelcoat 76PA FR by curing at workshop temperature (20°C). However, for optimum fire retardant properties, laminates must be post-cured before being put into service. The molding should be allowed to cure for 24 hours at 20°C, and then be oven-cured for 3 hours at 80°C

Packaging & Availability

Packaging Type
Packaging
Crystic® Gelcoat 76PA FR is supplied in 25Kg, 225Kg and 250Kg containers.

Storage & Handling

Storage
Crystic® Gelcoat 76PA FR should be stored in the dark in suitable, closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. Ideally, containers should only be opened immediately prior to use.
