Instructions for use
The bonding surface must be cleaned with acetone solution, and the surface must be completely dry before using a brush (no fibers must fall off) to apply primer evenly on the adhered surface. The thickness of the coating should be The tape can be pasted after the glue is dry.
Primer is a light brown transparent liquid. In order to improve the bonding performance, it is an adhesive that is coated on the surface of the adherend before gluing. It interacts with water molecules in the air , can produce high bonding force and has high temperature resistance, especially when used together with acrylic foam tape, it can achieve excellent bonding effect.
Instructions for use
, Bonding surface preparation
Use a fiber-free cloth dipped in isopropyl alcohol, acetone or toluene to clean the bonding surface.
Operation
Shake the bottle containing the primer vigorously before use.
Use special tools Or brush, roller (no fibers must fall off, apply the primer evenly on the bonding surface, the general coating thickness is ~.
, drying time
The drying time generally depends on the temperature, humidity, and coating thickness. .
Normal drying time minutes to hours
Optimum drying time minutes to minutes (temperature ℃, humidity)
During this period, it must be noted that the coating surface is absolutely free from contamination
, double-sided tape Bonding
Attach the double-sided tape to the dried coating surface and apply a certain amount of pressure.
Precautions
