To ensure maximum bond strength of your pressure sensitive labels from storage through application, Metalphoto of Cincinnati recommends the following storage and handling:
Store your labels in a plastic bag at room temperature conditions of 72°F (22°C) and 50% relative humidity. Storing labels at higher or lower temperatures may decrease the level of adhering performance.
BEFORE YOU BEGIN, HAVE THE FOLLOWING SUPPLIES:
Your pressure sensitive labels
An industrial cleaning solution or isopropyl alcohol
Clean rags or paper towels, and
A soft rubber roller
Ideal adhesive application temperature range is 70°F to 100°F (21°C to 38°C). Initial application to surfaces at temperatures below 50°F (10°C) is not recommended for most pressure sensitive adhesives because the adhesive becomes too firm to adhere readily.
Bond strength can also be improved with firm application pressure and moderate heat (for metal surfaces only), from 100°F to 130°F, causing the adhesive to develop intimate contact with the bonding surface.
STEPS TO PROPERLY APPLY YOUR ADHESIVE LABEL:
Clean and dry the mating surface before applying the label. It is important to remove all grease, oils, rust, waxes, and other contaminants that may interfere with adhesion.
Handle the label by its edges to avoid touching the adhesive.
Position one edge of the label on the surface, then using the roller or firm thumb pressure, move across the label to complete the application. This will prevent air from trapping between the label and the surface, and help the adhesive fasten into the mating surface. Adhesives will meet maximum bond strength after approximately 72 hours.
AVOID INCORRECTLY INSTALLED LABELS:
Do not apply labels to a dirty surface.
Do not pre-curl the (foil) label while peeling it from the backliner.
Do not touch the back, as the will contaminate the adhesive.
Do not loosely apply the label. All edges of the label must be firmly adhered to the surface.
Do not use a hard roller when applying the label. This could damage the label material.
NOTE: MPC recommends that you conduct a test of surface preparation and label adhesion before ordering labels or adhering actual production labels.
