Tesa 8854 can be adhered to the smooth surface of a thin tape, it is a very thin tape on the narrow and smooth surface provides high adhesion strength and very low rates of excess glue, technical support and service 189 * 228 * 610 * 07. The main speaker of the adhesive used in mobile phones, cameras and other internal structure protection unit. Model 8854 PET substrate thickness of 0.1 (mm) Width 1250 (mm) color white blue 250 words long-term temperature range (℃) suitable for mobile phone accessories brand Tesa short-term temperature resistance 250 (℃) Adhesive Acrylic extension coefficient 100? ? With the adhesive bond strength with the sticky surface contact area increases with increasing applied pressure helps to stabilize the adhesive contact with the sticky surface, thereby increasing the bonding strength. For best bonding results, the bonding surface must be clean, dry and tape applied optimal temperature range is 21-38 ℃, recommended if the initial bonding temperature below 10 ℃, suitable adhesive, so When the adhesive is too hard, and can not be firmly adhered to the object; however, if the adhesive already on, holding tack at low temperature also is satisfactory. Shelf-life at 21 ℃ and 50% relative humidity, under the original packaging state since the date of production shelf life of 24 months.
