Application: SIL08LH-101 is formulated for spraying as supplied. Optimal application temperature range is 70 – 90 F (21-
32 C). It is strongly recommended that the material be mixed before use. Apply in several thin, overlapping passes rather
than a single heavier coat; this will help avoid porosity, solvent entrapment, and sagging. The recommended wet film
thickness is 15 – 18 mils (0.38 – 0.46 mm) wet.

Storage and Handling: SIL08LH-101 should be stored in closed, opaque containers at temperatures above 40 F (4 C) but
not exceeding 77 F (25 C). Do not keep gel coat near catalyst storage areas. To avoid decomposition, keep away from
direct sunlight and excess heat. Refer to the Safety Data Sheet for further details on safety and storage.
