1. Before using 3M Glue, be sure to wipe the surface of the object to avoid dust or moisture affecting the adhesiveness of the adhesive paper.2. When using 3M glue, try not to touch the glue surface directly with your hands. Because there are sweat stains on the hands, skin care products, etc., these will have a release effect and will affect the glue.3. The larger the area of 3M adhesive on the surface to be evaluated, the better. This adhesive area is called the effective adhesive area. Generally, the effective adhesive area must be at least 70-80% of the total area before the properties of 3M adhesive can be used.4. The most suitable operating temperature for 3M glue is 25 degrees Celsius plus or minus 5 degrees, and the humidity is 50% plus or minus 10%. Because when the temperature is high, the 3M glue will be softer, and the fluidity of the 3M glue is relatively large, and it is easier to stick effectively with the adherend. On the contrary, when the temperature is low, the 3M glue will be harder and not easy to stick. When the operating temperature is lower than this, you need to find a way to increase the operating temperature. If it is not feasible to increase the operating temperature, apply more pressure when attaching the adhesive tape, such as using a scraper to press back and forth, or increase the standing time. It is best to place the adhesive tape face up.5. 3M glue is not completely solid, it is flowable like water. When the 3M glue is bonded to the adherend, it is not fast and completely fit, but the 3M glue flows slowly by itself and gradually develops into close contact and stickiness. If there is external pressure between these, the time required for close contact can be greatly shortened. Generally, pressure is required to make the effective Industrial Magnets reach 70-80%.
