3M4920 is 3M double-sided adhesive foam substrate in a double-sided adhesive, are VHB Adhesive (pressure sensitive adhesive department), thickness of 0.4MM, color is white 3M4920 3M4920 color, with superior viscosity, UV, good solvent resistance, but also has a soft, paste service and good properties, high tensile strength, shear strength, can be used in conventional screw fixation methods, rivets, spot welding replaced with double-sided adhesive tape to make the product surface is more smooth, beautiful, operation more simple, sealing better, more lasting effect, disassembly is very convenient. Performance Edit Item Test Method Test Unit static shear strength when 1500 g 22 ℃ 66 ℃ 93 ℃ time when 500 g 500 g density 0.8 g / cm stainless steel peel strength ASTM D3330 26 N / 10MM good solvent resistance Excellent UV resistance Long-term temperature resistance 93 ℃ 150 ℃ 3 short-shelf-life editor at 21 ℃ and 50% relative humidity, from the shelf life of 24 months from the date the original packaging under the state of manufacture. Applied Technology: With the adhesive bonding 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. 4 Application Editing: 3M4920 double-sided adhesive in compliance with ROHS environmental regulatory requirements, widely used in air conditioners, office furniture, bonding communications products, can replace the traditional method of fixing screws, rivets, etc., thereby improving product aesthetics.
