IOTA
IOTA 6250N/6250M is a two-component organic silicon gel, mainly used in
1. Sealing of IGBT modules and electronic components of optoelectronic equipment
2. Sealing of automotive electronic precision electrical circuits and hybrid circuit modules
3. Sealing of solar cells, sensors, high-power rectifiers, and rectifier bridge modules
Product features
1. Medium viscosity, transparent, two component
2. Room temperature curing or heating curing
3. Low hardness, low shrinkage, and no corrosion
4. Stable chemical properties, no precipitation of low molecular weight silicone oil
5. The D3-D10 cyclic content in IOTA 6250 is lower;

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℃, 120min, no flow; 30min, fully cured at 120℃.
3. The mixed rubber should be sealed and stored and used within the safe operation period, otherwise it will cure slowly and cause waste.
4. The curing speed of the rubber has a certain relationship with the temperature. The curing will be slower at low temperature.
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. During the vulcanization process, this product should avoid contact with organic compounds containing N, P, S, ionic compounds of heavy metals such as Sn, Pb, Hg, Sb, Bi, As, and organic compounds containing unsaturated groups such as acetylene, otherwise it will cause poor curing of the glue. Therefore, the compatibility test of silicone rubber and substrate should be carried out before use.
