LOCTITE® STYCAST US 1195

Features and Benefits

LOCTITE STYCAST US 1195, Urethane, Potting and Encapsulating
LOCTITE® STYCAST US 1195 is formulated for potting electronics or devices for protection against environmental hazards. This material exhibits high hardness compared to other urethane materials allowing improved durability and impact resistance. It's low Tg allows for better thermal cycle performance to meet low temperature requirements in harsh environments. LOCTITE STYCAST US 1195 passed internal flammability testing at 3 mm thickness.
