- Features and Benefits
The handling characteristics of Crystic 196E are especially suited to use in high ambient temperatures. Fully cured moldings made with Crystic 196E have excellent mechanical and electrical properties, with good rigidity, dimensional stability and impact resistance. The low levels of residual styrene in fully cured Crystic 196E makes it suitable for use where non-toxic, non - tainting laminates are required.
- Chemical resistance
A useful guide to the chemical resistance of fully cured Crystic 196E laminates in over 200 chemical environments can be obtained by referring to Crystic 196 in the current edition of Technical Leaflet 145.3 - Safe Chemical Containment.
Applications & Uses
- Applications
- Composites Processing Methods
- Recommended Applications
Crystic 196E is recommended for the manufacture of moldings for land transport, building, marine and industrial applications. It is a versatile resin suitable for use in hand and spray lay-up, filament winding, pultrusion, cold press molding and resin injection processes
- Formulation Guidelines
Crystic 196E should be allowed to attain workshop temperature (18°C - 25°C) before use. It requires the addition of a catalyst and an accelerator to start the curing reaction. The recommended accelerator is Accelerator E which must be thoroughly dispersed in the resin. This mix will remain usable for approximately one month at ambient temperature (25°C). Shortly before use, the catalyst should be added. The recommended catalyst is Catalyst M (or Butanox M50) which should be added at 2% into the accelerated resin mix, and thoroughly dispersed. For low taint applications, the catalyst should be Catalyst 0 (or Interox LA3), also at a 2% addition. It should be noted that resin which has been accelerated for several days may have a shorter pot life than freshly accelerated resin.

- Approvals
- Crystic® 196E is approved by Lloyd's Register of Shipping for use in the construction of craft under their survey.
Technical Details & Test Data
- Additives
Crystic 196E may be pigmented by the addition of up to 5% Crystic Pigment Paste. The addition of Crystic Pregel to Crystic 196E will enable its use as a barrier coat. Up to 40% of Pregel 17 or, where heat resistance is important, Pregel 27 may be used. Crystic 196E may be modified with Crystic Prefil F to produce low fire hazard laminates. The addition of certain pigments, fillers or extra styrene may adversely affect the food taint, toxicity and chemical resistant properties of Crystic 196E. Customers should therefore satisfy themselves that any additions made will give the performance required.
- Post Curing
Satisfactory laminates for many applications can be made with Crystic 196E by curing at workshop temperatures (20 ºC). However, for optimum mechanical and heat resistant properties, laminates must be post cured before being put into service. Moldings should be allowed to cure for 24 hours at 20ºC and then be oven cured for 3 hours at 80ºC. For low taint applications, moldings should be allowed to cure for 24 hours at 20ºC and then be oven cured for 3 hours at 85ºC. This should be followed by wet steam cleaning for at least one hour. If the molding is of a suitable shape, it can be filled with hot water (80ºC) for 2 hours instead of steam cleaning. The water should contain a perfume-free detergent, and several batches of clean water should be used for rinsing.
