Product description
Organopolysilazane IOTA 9108 is a liquid precursor polymer consisting of repeating Si-N units. It can be used as a thermosetting resin and a ceramic precurs. Under relatively mild conditions, the SiCN ceramic products with excellent temperature resistance are obtained, especially for high temperature resistant adhesives.
Applications
Ceramic matrix composites (CMCs)
Metal matrix composites
High temperature resistance to 1500℃
High temperature resistant adhesive
Anticorrosive coating
High temperature resistant anti-oxidation ceramic coating
Ceramic preform impregnated
Thermosetting resin
Organic and inorganic hybrid materials

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 ℃.
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 ℃, begin to crystallize above 1400 ℃. Ceramic product composition has great relationship with cracking atmosphere, SiC and Si3N4 under nitrogen or argon; mainly Si3N4 under Ammonia; 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 half year; opened polysilazane shelf life is depend on protection measures. Under sealed low temperature drying condition, the lifetime is more than two months.
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.
Clean
Proper cleaning method is important. After use, take acetone or solvent oil immediately to wipe the tool and clean. Once IOTA 9108 cured, the solvent cannot be washed away.
