It is recommended that storage temperatures should not exceed 25oC, and that containers should be stored away from
direct sunlight and not be opened until they are required for use. The shelf life of the resin under these conditions is
three (3) months.
CRYSTIC 125 PA is supplied in 225 kg steel containers. For the purpose of shipping, CRYSTIC 125 PA is class 3.0
in the IMCO Code (Page 3153)
HEALTH & SAFETY NOTES
Unsaturated polyester resins and resin systems.
The most important protective measure are:
- Correct storage
- Stock rotation
- Adequate workplace ventilation
- Fume extraction in work areas where vapour concentrations may be excessive.
- Use of fresh air masks in confined spaces or spray applications outside of spray booths
- Work place monitoring of vapour concentrations
- Good housekeeping
- Systematic work routines
- Competent personnel
- Supervision, training and instruction
- Fire precautions
- Correct disposal
- Points of Precaution
Above certain levels monomer and solvent vapors can be hazardous to health and safety. The safety risks are
associated mainly with fire and possible explosions. The risks to health come essentially from the build up of vapors
in the workplace in excess of certain limits and the limits applicable to the users’ country should be determined. In the
UK these are known as Occupational Exposure Standard (O.E.S.) and reference should be made to the Guidance Note
EH40 from the Health and safety Executive, currently in force and available from HMSO.
The symptoms of the more common vapors are similar, i.e. dry irritating throat, coughing, drowsiness and headache. Bothliquids and vapors may cause skin irritation and dermatitis to susceptible personnel.
What to do
Correct storage, stock rotation and handling will reduce safety risks. Sensible workshop lay out and systems of work
and good general and local ventilation sufficient to control the concentration of vapor below the O.E.S.’s will severely
limit or remove the health risks. Both health and safely risks can be substantially reduced by good housekeeping.
Proper procedures and equipment are important regarding respiratory matters especially when spraying is involved.
Reference should be made to BS 4275 1974 and BS 4667.
Part 3 1974 for guidance in the selection of suitable respiratory protection or to standards appropriate to the user’s
Contact with the skin must be avoided. Solvent resistant gloves and suitable protective clothing should be worn when
handling resin solutions; the solvents have a defatting action that leaves the skin prone to irritation and dermatitis.
