Fully cured laminates made with Crystic 701PAX have excellent strength retention in wet environments. Crystic 701PAX is compatable with most reinforcement types, including carbon fiber and polyaramids such as Kevlar
Applications & Uses

- Recommended Applications
Crystic 701PAX was developed primarily as a Vacuum Injection resin, but its properties make it suitable for use in other, similar techniques. The viscosity and exotherm characteristics of Crystic 701PAX make it particularly suitable for the manufacture of large structures by Vacuum Injection methods. Where longer geltimes are required, Crystic 701PA should be used.
- Formulation Guidelines
Crystic 701PAX should be allowed to attain workshop temperature (18°C - 20°C) before use. It requires only the addition of a catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50), which should be added at 1% - 2% into the resin. The catalyst should be thoroughly incorporated into the resin, using a low shear mechanical stirrer where possible. Geltimes of Crystic 701PAX and Crystic 701PA, using various catalyst levels, can be approximately determined from the table below.

Technical Details & Test Data
- Additives
The addition of fillers or pigment pastes can adversely affect the Vacuum Injection process and also the properties of the cured laminate. Users should seek advice from our Technical Service Department before making any additions.
- Post Curing
Satisfactory laminates for many applications can be made from Crystic 701PAX by curing at workshop temperature (20°C). For optimum properties, however, laminates should be post-cured before being put into service. The laminate should be allowed to cure for 24 hours at 20°C, and then be oven cured for 16 hours at 40°C or 3 hours at 80°C.
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 701PAX is supplied in 25kg, 200kg and 1 ton containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage
- Crystic® 701PAX 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 be opened only immediately prior to use.
