Material Engineering & Design Features

3M™ 201E combines a saturated crepe paper backing with a cross-linked rubber resin adhesive to provide a balance of adhesion, flexibility, and clean handling. The crepe paper construction allows the tape to conform to irregular surfaces while maintaining structural integrity throughout the masking process.

Key design features include:

• Crepe paper backing for improved flexibility and contour following
• Cross-linked rubber adhesive for dependable bonding performance
• Saturated backing for reduced slivering during removal
• Hand-tearable construction for easy application
• Controlled unwind technology for efficient dispensing
• Reliable adhesion without excessive residue under recommended conditions

Installation & Handling

• Apply to clean, dry surfaces before painting or coating operations
• Press firmly to ensure complete adhesive contact
• Suitable for low-temperature bake cycles up to 80°C
• Compatible with infrared and UV curing systems
• Remove after paint curing to achieve clean masking lines
• Designed for indoor applications only
• Avoid prolonged exposure to sunlight or outdoor weathering

Environmental & Compliance Notes

• Designed for indoor use only
• Store in a clean, dry environment
• Recommended storage conditions:
  • Temperature: 21°C
  • Relative Humidity: 50%
• Shelf Life: 12 months from date of manufacture when stored in original packaging
• Prolonged exposure to sunlight may make removal more difficult
