3M™ 468 Adhesive Transfer Tape is a firm acrylic pressure-sensitive adhesive (PSA) system. It features high ultimate bond strength, excellent high temperature performance and excellent solvent resistance. Bond strength increases substantially with natural ageing; 3M™ 468 is a long ageing and resistant product used extensively by the nameplate industry.
468 easily adheres to stainless steel and has high shear resistance properties. When the adhesive is properly applied to impervious materials it will resist solvent attack and adhesive softening through edge contact with mild acids and alkaline, oils, grease, gasoline kerosene, JP-4 fuel, and many other standard aromatic and aliphatic solvents. However, it is not recommended for uses where continuous immersion is required.
Excellent UV light resistance means it will not oxidise when exposed to air or sunlight. Excellent water resistance shows that there are no evident adverse effects on the bond of properly applied materials after immersion in 21°C water for about 100 hours.
Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact & thus improves bond strength. To obtain optimum adhesion, the bonding surfaces must be clean, dry, and well-unified. A typical surface cleaning solvent is isopropyl alcohol & water.
Ideal tape application temperature range is 21°C to 38°C. Initial tape application to surfaces at temperatures below 10°C is not recommended because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is satisfactory.
3M™ 468MP is well suited for bonding together a wide variety of similar and dissimilar materials such as metals, paints, wood, glass, and some plastics. An excellent adhesive for mounting nameplates and decorative trim, as well as miscellaneous joining and holding where a thin, long ageing bond is required.
