- Processing Information
Preparation
CW30338 CI contain fillers, which tend to settle over time. It is therefore recommended to carefully homogenize the complete contents of the container before use. In the storage vessels of the production equipment, the pre-filled products should be stirred up from time to time to avoid sedimentation and irregular metering.
Mixing
To facilitate stirring and removal, highly filled components are heated to 60 - 80°C in the original container (e.g. overnight in an oven). The resin component should be homogenized in holding tank A at 70 - 80°C under a vacuum of 1 -5 mbar, the hardener component in holding tank B at 30 - 50°C and a vacuum of 2 - 5 mbar.
Curing
To determine whether cross-linking has been carried to completion and the final properties are optimal, it is necessary to carry out relevant measurements on the actual object or to measure the glass transition temperature. Different gel and cure cycles in the customer’s manufacturing process could lead to a different degree of crosslinking and thus a different glass transition temperature. It should be noted that certain minimum curing temperatures and time are required to achieve the highest possible crosslinking density in the resin system. The minimum curing temperature for resin system CW30338 CI/HY30339 CI is 100 - 120 °C.

Safety & Health
- First Aid
- Contamination of the eyes by resin, hardener or casting mix should be treated immediately by flushing with clean, running water for 10 to 15 minutes. A doctor should then be consulted.
- Material smeared or splashed on the skin should be dabbed off, and the contaminated area then washed and treated with a cleansing cream (see above).
- A doctor should be consulted in the event of severe irritation or burns.
- Contaminated clothing should be changed immediately.
- Anyone taken ill after inhaling vapours should be moved out of doors immediately.
- In all cases of doubt call for medical assistance.
- Industrial Hygiene
Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed.
- Handling Precautions
Safety precautions at workplace Protective clothing yes Gloves essential Arm protector recommended when skin contact likely
Goggles/safety glasses yes Respirator/dust mask recommended Skin protection Before starting work Apply barrier cream to exposed skin
after washing Apply barrier or nourishing cream
Cleansing of contaminated skin Dab off with absorbent paper, wash with warm water and alkali-free soap, then dry with disposable towels. Do not use solvents
Clean shop requirements Cover workbenches, etc. with light coloured paper. Use disposable breakers, etc.
Disposal of spillage Soak up with sawdust or cotton waste and deposit in plastic-lined bin
Ventilation: of workshop Renew air 3 to 5 times an hour
of workplace Exhaust fans. Operatives should avoid inhaling vapours.
Storage & Handling
- Storage Conditions
The components have to be stored under dry conditions at 18-25°C, in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only following reanalysis. Partly emptied containers should be closed tightly immediately after use.
