silicone gel
ZJ-6250LC is a two-component silicone gel, mainly used for
Automotive electronic precision electrical circuits and hybrid circuits, solar cell modules
Sensors, high-power rectifiers, rectifier bridges, intelligent water meters
Sealing of electronic components, circuit boards, modules, etc. of optoelectronic equipment
Product features
Medium viscosity, transparent, two component
Room temperature curing or heating curing
After curing, there are no by-products, with characteristics such as low hardness, low shrinkage rate, and no small molecule silicone oil precipitation
Wide resistance to high and low temperatures, good damping performance, and weather aging resistance
Capable of reliably protecting sensitive microelectronic components from moisture and corrosion

- Before use, thoroughly mix components A and B in a 1:1 ratio. Stir for 5 minutes. It is recommended to use it after 5-10 minutes of vacuuming at -0.09MPa~-0.08MPa
- Temperature and curing time: 25 ℃, no flow starting from 120 minutes; Fully cure at 120 ℃ for 30 minutes.
- The mixed adhesive should be sealed, stored, and used up within a safe operating period, otherwise it will slowly solidify and cause waste.
- The curing speed of the adhesive is related to temperature to a certain extent, and curing will be slower at low temperatures.
- This product is not a hazardous material, but do not enter or eye contact. If accidentally splashed, rinse with plenty of water.
- The A and B components of the colloid must be sealed and stored to prevent leakage during transportation!
- Do not contact with N, P, S, plasma compounds such as sulfur, polysulfide, polysulfone or other sulfur containing materials, amine, polyurethane, amide and azide, organotin compounds and silicone rubber containing organotin catalysts to avoid poisoning the platinum catalyst poisoning and curing failure.
A group of 20Kg for component A and 20Kg for component B (small bucket),
Or a set of A component 200Kg and B component 200Kg (large barrel)
Store in a dry place for a storage period of 12 months. If it expires, it needs to be retested and can be reused after passing the inspection.
This type of product belongs to non hazardous goods and can be transported as general chemicals.
