Application field
- Household electric iron, microwave oven, induction cooker
- Automobile lamps, LED bulb lamp, T – shaped lamp
- PCB components are firmly bonded and sealed
- Construction machinery sealant, LCM border seal
Operation process
- Surface treatment: clean the bonded surface, clean and remove rust, dust and oil stains with cleaning agent. Can be used for a variety of materials, such as: glass, metal and most commonly used industrial plastics, to achieve bottomless coating bonding. However, some polymers may be less cohesive, such as polyethylene, polypropylene and PTFE. It is recommended to use PM1200 for primer in advance to obtain good bonding effect.
- Sizing: cut the glue nozzle to the required size and load the glue gun. Squeeze the glue onto the cleaned surface so that it is evenly distributed. For bonding, the adhesive surface can be closed and fixed. At room temperature and 55% relative humidity, the glue exposed to air will finish “crusting” in about 15 minutes. Therefore, all processing must be done before crusting.
- Curing: After crusting is completed, curing will continue from the inside out. The curing depth is approximately 3mm within 24 hours (room temperature, 50% relative humidity). Very deep sections, especially those with difficult contact with water vapor in the air, will require longer curing times. The lower the relative humidity the longer the curing time. The coated parts can be put into use after curing at room temperature for 24 hours.
- Note: after opening, it should be used up once or not. When it is used again, it should continue to be used after squeezing out the solidified part, without affecting the normal use.
