3M9448A (produced by 3M Shanghai subsidiary, and 3M9448HK produced by 3M Japanese subsidiary) is a non-woven substrate double-sided adhesive in 3M double-sided adhesive. The color is white and translucent. Has good initial tack and stickiness, easy die-cutting processing, good stability, good adhesion to plastic, rubber, rough surface; good sticking force at high temperature, long-term temperature resistance of 80 ℃, short-term temperature resistance up to 120 ℃; the color of the tape is white. 3M9448A specifications are: 1219MM * 50M * 0.15MM.
3M9448A is stored at room temperature and 50% relative humidity in the original packaging state for 12 months from the date of production.
The bonding strength of 3M9448A increases with the increase of the contact area between the adhesive and the adhered surface. The application of a stable pressure helps the adhesive to contact the adhered surface, thereby increasing the adhesive strength. To achieve the best bonding effect, the bonding surface must be clean and dry. The optimal temperature range for the application of the tape is 21-38 ° C. It is recommended that the initial bonding temperature is lower than 10 ° C, which is not suitable for bonding, so The adhesive at this time is too hard to adhere firmly to the object; however, if it is already attached, the holding force at low temperature is also satisfactory.
3M9448A meets the requirements of ROHS regulations and PFOS regulations in environmental protection. It is widely used in the processing industry, including the bonding of rubber strips and plastics in the rubber and plastic industry. Assembly of cotton, paper, toys and electronic parts.
