Our adhesive coated plastics are intended to be installed in the field, e.g., on electric circuit breakers where you cannot control the temperature an cleanliness. Ideally, the temperature will be between 50F-100F, and you'll use a clean cloth to remove most surface contaminants. The brown paper liner is designed to peel away easily in one piece – easier for the installer to clean, peel, press firmly, done.
What kind of adhesive? How long to achieve a permanent bond?
We begin with a high-quality permanent, indoor-outdoor, high-tack, 0.002" thick acrylic adhesive. The adhesive is briefly repositionable, which is important for industrial users who might not place the sign at a slight angle, then need some repositioning.
After one day the adhesive bond is nearly at full strength; maximum bonding strength is achieved after three days, at which time the bond becomes permanent and weatherproof.
