Brady 84827 electrical hazard caution sign, self-adhesive, polyester, 10w x 7h self-sticking polyester b-302 is a flexible polymer plastic over-laminated with a clear plastic coating to protect graphics against abrasion, sunlight, chemicals. Weathers up to 8 years outdoors, even longer indoors, and withstands wide temperature variations up to 230f. Flexible material conforms to most surfaces while protected graphics hold up to harsh environments, abrasion, and repeated spills and cleanings. Permanent, pressure sensitive adhesive forms a long-lasting bond to even the most difficult surfaces and shapes.
