colour
In addition to black, gray and white, it can also be produced in consultation according to the special colors required by customers
Adopt standards
MF897 silicone anti-mold sealant meets or exceeds the following standard specifications:
JC/T 885 SR, 0
ASTM C920S type, NS type, 25 grade
Application method
Surface cleaning
Remove grease, dust, water stains, frost, surface dirt, etc. at the joints to make them clean, dry and free of dirt.
Glue injection
The area connected with the seam should be covered with masking tape to ensure a neat and beautiful sealant line.
For some material surfaces, primer may be required to ensure good adhesion. It is recommended to do adhesion test before the project starts.
Continuously squeeze MF897 silicone anti-mold sealant into and fill up the joints (the sealant can be applied with a pneumatic glue gun and other glue injection equipment). When using a pneumatic gun, the operating pressure should be adjusted to prevent bubbles from being generated during glue injection.

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 is not yet skinned, level the sealant with appropriate strength.
After leveling, remove the masking tape immediately. Do not use liquids such as water, soapy water, or alcohol to help level it.

Precautions and precautions
The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
The glue mixed at room temperature should be used during the application period.
Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
avoid contact with children; do not contaminate food, medicine or cosmetics.
The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.
