Applications & Uses
- Markets
- Recommended Applications
CRYSTIC 4044T V01 has been specially developed for the production of liners to be used in the pipe relining industry. Fully cured laminates offer high chemical resistance and mechanical properties, together with excellent long term property retention.
- Formulation Guidelines
The following formulation is recommended for hot curing (80 – 85°C)
- CRYSTIC 4044T V01 : 100 parts
- Perkadox 16 : 0.5 - 1 %
- Trigonox C : 1 – 1.5 %
Perkadox 16 and Trigonox C are products from AKZO.

CRYSTIC 4044T V01 is type 1140 according to the German standard DIN 16946 Teil 2 and group 3 according to DIN 18820 Teil 1.
Technical Details & Test Data
- Reactivity
The ambient temperature, the quantity and the type of catalyst will control the reactivity of the resin. The time to pic of CRYSTIC 4044T V01 with 0.8% Perkadox 16 and 1% Trigonox C at 80°C is 7 to 8 minutes.
- Additives
Since certain pigments, fillers or extra styrene may the affect properties of CRYSTIC 4044T V01 their effect should be evaluated before addition to the formulation.
Safety & Health
- 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, headaches. Both liquids and vapors may cause skin irritation and dermatitis to susceptible personnel
- 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 ventilatio
- 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
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 4044T V01 is supplied in 225 kg or 1100 kg containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage
- Crystic® 4044T V01 should be stored under cover in the dark in the container in which it is supplied. Storage temperatures should not exceed 20°C. Moreover, Crystic® 4044T V01 should be periodically stirred to avoid sedimentation during the storage period
