Application

Device surface protection in electrical, automotive, electronic industry and other fields

How to use

Operation process

Clean the surface: the surface of the sticky or coated material is cleaned, and the rust, dust and oil are removed with cleaning agent.
Sizing: Cut the nozzle to the required size and load it into the glue gun. Squeeze the glue solution onto the cleaned surface for an even distribution.
Curing: the coated parts are placed in the air, and can be put into use after the room temperature surface is dry.
Note: After opening, use it as much as possible once, once not used up, and then use it again, after squeezing out the cured part, continue to use without affecting normal use.
