Brady B-302 is an indoor/outdoor high performance pressure sensitive safety sign, and is surface printed polyester, with a polyester overlaminate.

Use:
Brady B-302 is used for safety signs, identification of fire alarms, extinguishers, and emergency exits.

Special Properties:
Brady B-302 is particularly suited for outdoor applications, and in harsh environments where excellent abrasion and chemical resistance is required beyond a surface printed label. B-302 has a cold temperature adhesive that makes the sign able to apply at 0°F (-18°C).

Adhesive Type:
Permanent cold temperature pressure sensitive acrylic
