Application Techniques
To obtain maximum adhesion, surfaces must be unified, dry, and free of
contaminants. Surface contact is essential to adhesive performance. To maximize
contact on a substrate:
• Clean surfaces with low strength solvent such as isopropyl alcohol (rubbing
alcohol) or heptane.*
• Apply firm pressure to help increase the cold flow and contact of the adhesive with
the substrate.
• Allow time (dwell) to increase the surface contact and adhesion (see illustrations
below).
*Note: Be sure to follow the manufacturer’s precautions and directions for use when
using solvents.
Environmental
Exposure
Colored and transparent 3M™ Bumpon™ Protective Products are intended for
interior applications where resilience and other physical properties will remain
unchanged. When exposed to UV light for extended periods some slight
discoloration or yellowing may occur.
Bumpon products may be used outdoors in a protected area with some discoloration
possible; colored Bumpon products may chalk.
Simultaneous exposure to high humidity and temperature may degrade (soften) the
Bumpon product urethane.
