Something About MS Sealant
1. When produce MS sealant, the mixing equipment should have the function of vacuum, heating, cooling, nitrogen inlet, also with high speed dispersion.
2. Dehydration is the key point during production process. There are two ways of dehydration, physics or chemical, such as dry the powder before production,heating,vacuumize, add A171 etc. We suggest to control the water content of powder under 500ppm, temperature between 70℃ to 90℃.Catalyst and cross-linker can be added when temperature under 40℃.
3. DIDP as plasticizer can be added when mixing the raw materials of MS sealant. DIDP can make hardness less and flexibility more.If wihout DIDP, DOP can be as an equivalent and adjust the viscosity, but its perfrmance not as well as DIDP.
4. Bulk MS sealant should be packed into the metal bucket and well sealed, to avoid heat and humidity. Under the condition of dry environment and well sealed, storage time of MS sealant usually is one year.
5. Small package of MS sealant can be paper cartridge, sausage film and plastic cartridge, package materials should be good air maintenance.
