EPUSIL U 110
DESCRIPTIOPN
Epusil
U 110 is a urethane encapsulating compound, two
components, room temperature curing. The cured U 110
is, flexible, y high tensile elongation and high
thermal shock resistance, electrical properties and
adhesion to a verity of material. The U 110 has
exceptional hydrolytic stability. The U 110 cures
very well at room temperatures.
