69 (3/4"X66FT) 3M

3M Glass Cloth Electrical Tape 69 with Silicone Pressure-Sensitive Adhesive Data Sheet May 2014 Description 3M Glass Cloth Electrical Tape 69 is a white glass cloth tape with a high- temperature thermosetting silicone pressure-sensitive adhesive. It is designed for use in 600-volt dry location applications motors, and transformers with and without varnish coating. Key attributes like high mechanical strength and resistance to high temperatures provide excellent performance. The thermosetting adhesive provides an increased bond once applied in areas of high ambient temperatures. The thermosetting adhesive provides elevated temperature performance up to Class N 392F (200 C) temperature rating. This tape provides insulation and solvent-resistant protection for use as coil cover, anchor, banding and core, layer and crossover insulation. This tape features a non- corrosive adhesive. It is conformable, printable and flame retardant. Agency Approvals, Meets Requirements of: Self Certifications, Military Specification No. Mil-I-19166C MIL Specs UL Recognized Component listing for 200 C (Guide OANZ2, File E17385) CSA Accepted Component 180 C, File LR93411 RoHS 2011/65/EU RoHS 2011/65/E means that the product or part does not contain any of the substances in excess of the maximum concentration values (MCVs) in EU RoHS Directive 2011/65/EU. The MCVs are by weight in homogeneous materials.
