Material Notes:
Room temperature curing, low modulus urethane conformal coatingAPTEK 2506-A/B is an unfilled, two component, electrically insulating, transparent, flexible urethane coating system designed for the encapsulation and protection of electrical/electronic components mounted on printed circuit boards. Capable of curing at RT, rapid cure with low/moderate heat cycle; Non-TDI based for safety; Excellent reversion resistance for good physical stability under high heat and humidity environments; Tg below -55ºC for excellent low temperature cycling, storage and performance; Excellent substrate adhesion; superior to silicones; Fluoresces under black-light (UV)APTEK 2506-A is a blue unfilled polyol resin. APTEK 2506-B is a amber colored organic isocyanate which make cause severe eye and skin irritation with direct contact..Information provided by Aptek Laboratories, Inc.
