Adoption standards:
JC/T2560-2020 "Corner structural sealant for building doors and windows"; Q/
ZZY 037-2022 "Polyurethane corner sealant for building doors, windows and curtain walls".
Instructions:
Remove dirt, dust, oil, frost, etc. from the surface of the base material; place the plastic glue
nozzle on the open bottle mouth and tighten it, and use a special 1:1 double-bottle glue gun to
inject glue. Uncured glue can be cleaned with special cleaning agents (or other solvents such
as alcohol).
Precautions:
● The initial 20g of mixed glue may not be fully mixed and is not recommended for use.
●The glue mixed at room temperature should be used during the construction period.
Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty
of water and see a doctor if necessary; avoid contact with children; do not contaminate
food, drugs or cosmetics.
The heavier workpieces to be bonded should be prevented from moving before they are completely solidified. If
movement is necessary, measures should be taken to secure them.
Recommended usage conditions: temperature 15~35℃, relative humidity 40%~80%; if the temperature
and humidity are lower than the recommended lower limit, the corner glue will solidify slowly; if it is higher than the
recommended upper limit, the construction time will be shortened.
Package:
1:1 double plastic bottle packaging: 600ml per group; 9 groups per box
Storage:
Can be stored in a cool, ventilated and dry place for 6 months.
transportation:
This product is non-dangerous goods and can be transported by train, car, ship and airplane.

MF322 two-component polyurethane corner sealant is a solvent-free, two-component, room temperature
curing structural sealant. It is mainly used for bonding and sealing between aluminum corner codes and profile
cavities in aluminum alloy door and window structures. It is also suitable for bonding wooden doors,
windows and doors. For different processed materials, such as wood, building materials, ceramics and
Metals, etc. have good adhesion.
