| APTEK 2503-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. Ideal for repair-ready-to-use; Fully compatible with APTEK 2503-A/B conformal coating as well as other commercially available urethane coatings; Excellent reversion resistance for good physical stability under high heat and humidity environments; Tg below -70ºC for excellent low temperature cycling, storage and performance; Excellent substrate adhesion, superior to silicones; Exceeds NASA outgassing requirements for high vacuum environments; Fluoresces under black-light (UV) to facilitate QC inspection of coating coverage of repaired components/substrates. APTEK 2503R-A is an unfilled polyol resin containing solvent and is thus considered a flammable liquid and should be treated with caution. . APTEK 2503R-B is an organic isocyanate and is safe to handle when used properly. . Information provided by Aptek Laboratories, Inc. |
