Cable-End Encapsulation

COLTCAST HEAVY DUTY and COLTCAST FLEX are specialized, low-viscosity polyurethane resins for use in cable-end connectors and cable-end connection boxes, protecting from any factor that can jeopardize their function and performance (such as humidity, water, dust, corrosive environments, mechanical/chemical/thermal/physical shock, ants etc.) and providing impact, chemical and temperature resistance with minimum shrinkage for electrical connections up to 1KV, prolonging their service life.

COLTCAST series is provided in handy, easy-to-use, dual chamber pouches, designed to offer effective and problem-free on-site application, without the need to use a scale (pre-weighed packaging) or any other specialized application equipment.
