Range of Application:
Benefit it’s good resistance low temperature ability, MF840H polysulfide sealant is specilized for manufacture insulating glass
in low temperature and polar latitudes area.
Package:
MF840H Polysulfide has three packages way:
Large Package: Com A 300kg/ barrel, Com B 30kg/barrel
Medium Package: Com A 30kg/ barrel, Com B 3.6kg/barrel
Small Package: Com A 4kg/ barrel, Com B 0.48kg/barrel
Storage:
Shelf-life: 12 months stored in cool(below 27℃), dry and ventilated places.
NOTES
- Polysulfide sealant can’t mixed with silicone sealant, because the adhesion of mixed sealant not stable.
- The operating temperature should not below 5℃, because the curing time will be influenced when below 5℃.
