description
1. Product Features
High bonding force: 3MK520 can form a strong bond with a variety of materials, especially suitable for the surfaces of AAS, ABS, AES, EPDM, PP, PVC, PU, PC and other materials.
High temperature resistance: The product has good high temperature resistance and is suitable for occasions that need to work in high temperature environments.
Speed up the speed of tape sticking: After using 3MK520 to treat the adhesive surface, the speed of tape sticking can be significantly accelerated, improving work efficiency.
Increase the adhesive force: By increasing the bonding area and bonding strength between the adhesive surface and the tape, 3MK520 can significantly improve the adhesive force and ensure the firmness of the adhesive.
2. Usage method
Cleaning the surface: Use 50% acetone solution to clean the bonding surface to ensure that there are no impurities such as oil, dust, etc. on the surface.
Drying the surface: The surface to be cleaned is completely dry.
Applying primer: Use a brush without fiber shedding to evenly apply 3MK520 on the bonded surface, with a coating thickness of 0.05mm.
Drying the primer: The tape can be pasted only after the primer is dry. The drying time generally varies depending on the temperature, humidity, and coating thickness. The normal drying time is 1 minute to 1 hour, and the optimal drying time is 10 minutes to 30 minutes (temperature: 23°C, humidity 65%).
3. Precautions
Storage conditions: 3MK520 should be stored in the original container, the temperature should be kept at 4°C to 38°C, and the relative humidity should be kept at 0% to 95%.
Safety of use: Please shake well before use and use in a well-ventilated environment. Avoid direct contact with skin, eyes, etc. If accidentally contacted, please rinse immediately with plenty of water and seek medical attention.
Shelf life: Please pay attention to the shelf life of the product and avoid using expired products.
4. Application scenarios
3MK520 is widely used in occasions where the adhesion of the tape needs to be enhanced, such as screen window pasting, automotive interior sealing strip pasting, etc. At the same time, it is also suitable for various industrial applications where the adhesion needs to be improved.
