◎Glue injection
Apply masking tape to areas where joints meet as required to ensure a clean
and beautiful sealant line.
● For non-porous material surfaces, there is usually no need to apply primer to achieve good adhesion.

To ensure good adhesion, it is recommended to conduct an adhesion test before starting the project.

●Continuously squeeze MF890 silicone sealant into and fill the joints (dense
Sealing can be carried out using pneumatic glue guns and other glue injection equipment). make
When using a pneumatic gun, the operating pressure should be adjusted to prevent bubbles from being generated during glue injection.
● When the surface of the sealant has not yet formed a skin, use appropriate force to flatten the sealant.
