Solvent:
Polysilazane IOTA 9118 can be diluted with various polar or non-polar dry solvents. It is sensitive to water, alcohol solvents, hydrolysis or alcoholysis reaction, to make the product deteriorate. And it should avoid contact with acid, alkali and other proton type substances.
Curing conditions:
IOTA 9108 can be cross-linked under the temperature of 120-180 ° C, curing can be done in air or inert atmosphere.
IOTA 9108 can also do hydrosilylation reaction by platinum catalyst , curing at 80-100 ºC.
The curing time depends on the curing temperature and the amount of catalyst, usually 2-5 h.
Cracking conditions:
First, IOTA 9108 cured product converted to amorphous ceramics by high temperature cracking, eventually get crystalline ceramics. It is amorphous product below 1400 ºC, begin to crystallize above 1400 ºC. Ceramic product composition has great relationship with cracking atmosphere, SiC and Si3N4 under nitrogen; mainly SiOCN under air conditions. In addition, the cured product cracking is easily influenced by filler, and result affects the composition of the final ceramic product.
Shelf life:
Shelf life of unopened polysilazane IOTA 9108 is one year; opened polysilazane shelf life is depend on protection measures. Under sealed low temperature drying condition, the lifetime is more than two months.
Clean:
Proper cleaning method is important. After use, take solvent oil immediately to wipe the tool and clean. Once IOTA 9108 cured, the solvent cannot be washed away.
Precautions:
When use polysilazane, it should be in a ventilated, dry environment and with the necessary protective measures such as gloves, masks, goggles; We shouldn't put the uncured IOTA 9108 near fire, humid air and water.
