Storage Condition

LARMOR® YIL series is a light curable material; protect this product from all sources of ultraviolet light, including
fluorescent lighting and sunlight to prevent premature curing. It is recommended that this coating be stored in
a dry place in unopened, undamaged, original containers at temperatures between 15°C and 30°C. Storage or
shipment in cold conditions may result in a phase separation which is reversible and is corrected by heating for
24 hours at 50°C. If possible, the container should be gently rolled to assure uniform dissolution during this heating process.

Shelf Life

LARMOR®YIL series has a recommended shelf life of 12 months from the date of manufacture, provided that
the above stated storage conditions are properly maintained.

Safety Information

This product may cause skin and/or eye irritation and skin sensitization. Material safety data sheet for all products

also available from your Polytech sales representative. All safety and handling recommendations should
be followed carefully.

Filtration

LARMOR®YIL series is manufactured using fine filtration techniques designed to eliminate fibre strength problems and ensure uniform product performance.
