Why Choose 3M™ 3903
3M™ 3903 Cloth Tape is a practical choice for industrial users who need a flexible, conformable and easy-to-use cloth tape for general holding, bundling, sealing, protection, and maintenance applications.
Its cloth construction makes it easier to conform around irregular shapes than rigid film tapes, while the coated backing provides resistance to moisture for many general-purpose applications.
For OEM and industrial customers, Yousan can provide tape converting services including:
- Custom slitting
- Narrow-width rolls
- Custom roll lengths
- Rewinding
- Custom cutting
- Kiss cutting
- Die-cut tape components
- OEM converting
Installation Guide
1. Clean the surface
Remove dust, oil, grease, moisture, and other contaminants.
2. Dry the substrate
Make sure the application surface is clean and dry before applying the tape.
3. Cut or tear the required length
3M™ 3903 can be cut or torn manually according to the application.
4. Position the tape
Align the tape carefully before applying it.
5. Apply with firm pressure
Press the tape firmly onto the substrate to maximize adhesive contact.
6. Avoid excessive stretching
Apply the tape without unnecessary tension to minimize edge lifting or recovery.
7. Inspect the application
Check the tape edges and bonding area to ensure good contact.
Storage
Store 3M™ 3903 in its original packaging in a clean and dry environment, away from direct sunlight, excessive heat, moisture, and contamination.
Recommended storage conditions and shelf life should be confirmed using the current 3M technical documentation applicable to the specific product configuration.
FAQ
Q1: What is 3M™ 3903 Cloth Tape used for?
It is a general-purpose cloth tape suitable for applications such as bundling, holding, sealing, protection, maintenance, repair, and industrial masking.
Q2: Is 3M 3903 waterproof?
The polyethylene-coated cloth backing provides water resistance, but the tape should not automatically be considered a permanently waterproof sealing solution for submerged or high-pressure applications.
Q3: Can 3M 3903 be torn by hand?
Yes. The cloth construction makes the tape convenient to handle and manually tear for many general-purpose applications.
Q4: Can 3M 3903 be used for cable bundling?
Yes. Its flexible cloth construction makes it suitable for many bundling and temporary securing applications.
Q5: Can 3M 3903 be used outdoors?
Outdoor suitability depends on exposure to UV radiation, weather, temperature, moisture, and the required service period. Testing under actual conditions is recommended.
Q6: Can 3M 3903 be used on plastic?
It can be evaluated on many plastic substrates. For low-surface-energy plastics such as polypropylene or polyethylene, adhesion testing is particularly important.
Q7: Can Yousan slit 3M 3903 into narrow rolls?
Yes. Yousan can provide custom slitting and rewinding according to the required width and roll length.
Q8: Can 3M 3903 be die-cut?
Yes. Depending on the required shape and quantity, the tape can be converted into custom die-cut parts.
Q9: Is 3M 3903 suitable for permanent structural bonding?
No. Cloth tape should not be treated as a replacement for structural bonding systems. It is better suited to general holding, bundling, sealing, protection, and maintenance applications.
