Crystic 703PA has excellent mechanical properties and impact resistance. It is compatable with most reinforcement types.
Applications & Uses
- Applications
- Composites Processing Methods
- Recommended Applications
Crystic 703PA 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 703PA make it particularly suitable for the manufacture of large structures by Vacuum Injection methods.
- Formulation Guidelines
Crystic 703PA 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 702PAX and Crystic 702PA, using various catalyst levels, can be approximately determined from the table below.

Regulatory & Compliance
- Approvals
- Crystic® 703PA is approved by Lloyd's Register of Shipping for use in construction of craft under their survey.
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 the advice of Scott Bader’s Technical Service Department before making any additions.
- Post Curing
Satisfactory laminates for many applications can be made from Crystic 703PA by curing at workshop temperature (20°C). For optimum properties, however, laminates should be postcured 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
- Regional Availability
- Packaging
- Crystic® 703PA is supplied in 25kg, 225kg and 1.1 ton containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage
- Crystic® 703PA 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.
