Product Description

                                      SFY-131
                  (Flame Retardant Silicone for Potting)
SFY-131 is a two-part with good flow ability addition curing RTV silicone rubber. It is mainly designed for electrical and electronic potting, such as power supplies, connector, sensor, relay, high voltage resistor pack, and LED potting. It is suitable for batch processing or automated dispensing. With different colors for better distinction, base is black or dark grey and curing agent is white. It can be cured in a 1:1 ratio by weight or volume either at room temperature or elevated temperature for faster processing. The cured mixture is a black flexible elastomer. The elastomer has excellence in electrical properties and waterproof, self-extinguishing (UL94V0 approved), and weather resistance. Those properties are not significantly affected by the changes of temperature.

Features:
1. No corrosive and no cure by-product.
2. Equal amount of mixing ratio, good fluidity, easy processing.
3. Easy distinction of the two parts and inspection of complete mixing.
4. No significant exotherm or shrinkage during curing.
5. Flexible schedule, of curing can be cured at room temperature (R.T.) or at elevated temperature.
6. Very stable to changes of temperature, stability over wide temperature range (-50 to 200 oC).
7. UL 94V0 approval (E120665).
8. Excellent dielectric properties for maintaining and protection of existing electrical insulation requirements.
9. Excellent weather resistance and waterproof property for protection from moisture and dust contamination.
10. Relative easier removal benefits to repair of electrical/electronic devices.
11. Green environmental protection materials.

FAQ

 1. How to operate the electronic potting silicone rubber?

 

1). RTV-1 electronic potting silicone rubber: handled with guns, needle infection or directly infused
 2). RTV-2 electronic potting silicone rubber: stir---vacuum and de-air---perfusion. 
The mixing ratio of our electronic potting silicone rubber, HY210, HY215 is 10:1, condensation mold silicon rubber can be operated like this.
 3). Addition type electronic potting silicon rubber: the mixing raito is 1:1 or 10:1.
If in10:1, it is normally operated by labor, because it is easy to cause uneven curing if by machine,.
If 1:1, it is normally operated by machine, suitable for mass industrial production and helpful for time saving, labor cost saving and efficiency increasing.

 

 
2. Does SFY-131 contain any solvents?
No. SFY-131 does not contain any kind of solvents. SIFEL is naturally liquid type without any solvent.
 
3. What are the current applications for SFY-131?
SFY-131 is popular in automotive industries as well as in other industries where weather resistance, chemical resistance with high and low temperature required.
 
4. What is the thermal conductivity of SFY-131?
It is 0.5 W/m.K.
 
5. Does the outside environment affect silicone?
No. Silicone is not affected by extremes of weather – hot, cold, dry, wet, or humid. It also has excellent resistance to UV and ozone degradation.
 
6. How do I store silicone compounds?
Silicone compounds should be stored in a dry environment away from direct sunlight and heat, and at a temperature of less than 25C.
 
7. Is silicone toxic?
Silicone is considered to be a very safe polymer with virtually no toxic effects in most environments. Also, as silicone is not considered as hazardous waste it can be disposed of in accordance with the local regulations regarding waste disposal.
