IOTA
IOTA 6250H is a high temperature resistant silicon gel, mainly used for
1. Sealing of IGBT modules and electronic components of optoelectronic equipment
2. Applied to automotive electronic precision electrical circuits and hybrid circuit modules
3. Solar cells, sensors, high-power rectifiers, rectifier bridge modules
Product features
1. Medium viscosity, transparent two-component silicone gel can be cured at room temperature or at high temperature
2. It has low hardness, low shrinkage, no corrosion, no precipitation of low molecular weight silicone oil, and stable chemical properties
3. Capable of reliably protecting sensitive microelectronic components from moisture and corrosion
4. It has better heat resistance than ordinary silicon gel

Operation and Safety
1. Before use, mix components A and B in a ratio of 1:1. Stirring time 5min. It is recommended to use after degassing for 5-10 minutes under -0.09MPa~-0.08MPa vacuum.
2. Temperature and curing time: 25℃, 2.5 hours to start thickening; 30min to fully cure at 120℃.
3. The mixed rubber should be sealed and stored and used up within the safe operation period, otherwise it will slowly cure and cause waste.
4. The curing speed of the rubber has a certain relationship with the temperature, and the curing will be slower at low temperatures.
5. This product is non-hazardous, but do not put it in the mouth or eyes. If it is accidentally splashed, rinse with plenty of water.
6. The A and B components of the colloid must be sealed and stored, be careful of leakage during transportation!
7. Do not contact with N, P, S, plasma compounds such as sulfur, polysulfide, polysulfone or other sulfur-containing materials, amines, polyurethanes, amides and azides, organotin compounds and silicone rubber containing organotin catalysts to avoid poisoning the platinum catalyst and preventing curing.
