- Recommended Applications
CRYSTIC 115 NT can be used for the production of filled castings or for reinforced laminates on flat molds.
- Formulation Guidelines
The following cold curing formulation is recommended:
- CRYSTIC 115 NT : 100 parts
- Catalyst M : 1 to 2 parts
- Accelerator E : 1 to 4 parts
Catalyst M is a Méthyl Ethyl Kétone Peroxyde at 50% such as the Butanox M 50 from AKZO. Accelerator E is a cobalt octoate with 0,4% active cobalt . Catalyst and accelerator should not be mixed directly together as they will react with explosive violence.

Technical Details & Test Data
- Gel Time
The ambient temperature, the quantity and the type of catalyst will control the gel time of the resin.

- Additives
Since certain pigments, fillers or extra styrene may the affect properties of CRYSTIC 115 NT their effect should be evaluated before addition to the formulation.
- Post Curing
For most applications satisfactory result will be obtained by curing at room temperature (20°C). Some improvement in properties may be obtained by post-curing 16 hours at 40°C after release from the mold.
Safety & Health
- Health and Safety Information
The most important protective measures to be taken with unsaturated resins and resin systems are:
- Correct storage
- Stock rotation
- Adequate workplace ventilation
- Local extraction where vapor
- Concentrations may build up or are high
- Use of fresh air masks in confined spaces or spray applications outside of spray booths
- Work place monitoring of vapor concentrations
- Good housekeeping
- Systematic work routines
- Competent personnel
- Supervision, training and instruction
- Fire precautions
- Correct disposals
- Points of Caution
Monomer and solvent vapor concentrations above certain levels can be hazardous to health and safety. The safety risks are associated essentially with the fire and possible explosions. The risks to health come mainly from the build up of vapors in the workplace in excess of certain limits and the limits applicable to the user’s country should be determined. The symptoms of the more common vapors are similar, i.e. dry irritating throat, coughing, drowsiness, and headache. Both liquids and vapors may cause skin irritation and dermatitis to susceptible personnel.
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 115 NT is supplied in 225 kg or 1100 kg containers. Bulk supplies can be delivered by road tanker.
- Variants
CRYSTIC 115 is a thixotropic and non accelerated version. Variants are available with a minimum quantity of order.
Storage & Handling
- Shelf Life
- 9 Months
- Storage
- Crystic® 115 NT should be stored between 5°C and 25°C in the original, unopened container in a dry, well ventilated place. Protect from freezing and direct sunlight. Avoid contact with oxidizing agents. If stored outside of these recommendations, shelf life will be significantly reduced.
