3M VHB Cleaner

Isopropyl Alcohol is a solvent used to clean a surface prior to adhesion. Sold in 1 Litre Containers.

Surface Preparation Details.

To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Typical cleaning solvents are 3M™ VHB Cleaner, a mix of isopropyl alcohol and water or heptane.Be sure to follow solvent manufacturer's directions for use and precautionary warnings when using solvents (Steps A & B).Bond strength is dependent upon the degree of adhesive-to-surface contact developed. Firm application pressure helps better adhesive contact and thus improves bond strength (Steps C & D). After application, the bond strength will increase as the adhesive flows into the surface. At room temperature approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. In some cases bond strength can be increased and ultimate bond strength can be achieved more quickly by exposure of the bond to elevated temperatures (eg. 70C for 1 hour).m This provides better adhesive wetout onto the substrates.
