- For Best Results
- The surfaces you wish to bond should be clean and free of oil, moisture and dust. If the surface temperature is below 40°F, it may be difficult to achieve a proper bond.
- Do not use a pressure-sensitive adhesive product where it will be exposed to temperatures lower or higher than those designated for each product. Heat can destroy the effectiveness of the bond and extreme cold can cause the adhesive to harden and not adhere properly.
- When the tape is applied, use firm hand or lamination pressure to achieve contact between the adhesive and the surface to which it is applied. Hand rollers or nip rollers may be needed for certain products or applications.
Consult your AR sales representative if you need additional information.
- Applications

Safety & Health
- Safety Data
- The base polymer of MA-128 has passed cytotoxicity, skin irritation and skin sensitization testing conducted by an independent laboratory. The stabilizer package added to the base polymer has also been tested as part of a separate adhesive family and has passed cytotoxicity, skin irritation and skin sensitization testing conducted by an independent laboratory. Additional safety information is available upon request.
Storage & Handling
- Shelf Life
- 1 Year
- Shelf life of Unconverted product
- Not to exceed one year from date of manufacture
- Storage of Pressure-Sensitive Adhesive Tapes
- Pressure-sensitive adhesive tapes function as a mechanical product however, the adhesive itself is a chemical composition that can be sensitive to environmental conditions. A purchaser of pressure-sensitive adhesive products should be aware of the shelf life of each product and not purchase more than it can use before the expiration date. Shipping and storage conditions affect shelf life. The optimum storage temperature is 70 °F (21 °C). Cool, dry storage is recommended.
- Recommended Storage of Unconverted Product
- 21 ± 11 °C (50% ± 20% RH)
