Storage Condition

LARMOR®YR-003 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.
