Answer:
For maximum bonding, apply the tape to clean, dry surfaces between 16°C and 27°C (60°F to 80°F). The vinyl backing resists most common industrial solvents, but exposure to ketones, chlorinated hydrocarbons, and esters should be avoided to prevent swelling or curling.
To achieve rated adhesion performance with 3M™ 764 vinyl tape, observe the following surface and environmental guidelines:
- Application Temperature: Best results occur when applied to a clean, dry substrate at temperatures between 60°F and 80°F (16°C to 27°C).
- Solvent Resistance: While vinyl resists many standard general-purpose solvents, care must be taken to avoid exposure to ketones, chlorinated hydrocarbons, and esters (commonly found in commercial lacquers, thinners, degreasers, and paint strippers), as these agents can cause the PVC backing to swell or curl at the edges.
- Storage Conditions: Store in the original carton at 60°F to 80°F (16°C to 27°C) and 40% to 60% relative humidity. Recommended shelf life is 18 months from the date of manufacture under these conditions.
