Fire resistance electronic silicone potting compound manufacturer

Fire resistance electronic silicone potting compound manufacturer
Product Description
SFY-161 is a solventless, no odor, two-part silicone rubber, specially designed for electrical and electronic potting and encapsulating uses. It is suitable for batch processing or automated dispensing. With different colors for better distinction, SFY-161A and SFY-161B are dark gray and cream white, respectively. 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 gray flexible elastomer. The elastomer has excellent thermal conductivity, electrical and waterproof properties, also with excellent fire and weather resistance. Those properties are not significantly affected by the changes of temperature.
Features:
1. No toxicity, solventless, no odor and no cure by-product.
2. Equal amount of mixing ratio, good fluidity, easy processing.
3. No significant exotherm or shrinkage during curing.
4. Flexible curing schedule, can be cured at room temperature (R.T.) or at elevated temperature.
5. Very stable to changes of temperature, stability over wide temperature range (-50 to 200 oC).
6. Good fire resistance, UL94V0 approval.
7. Excellent thermal conductivity.
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.

FAQ
1. Do you supply UL grade materials?
Answers: Yes, we manufacture and supply some of our epoxies/hardener and liquid silicone rubber that are formal listed by UL under the following files:
2. Are epoxy potting compounds or silicone potting compounds better to be used?
Answer: It is exactly dependent on customers’ requirements.
3. Can I add some materials to lower viscosity?
Answer: Whenever you add a thinning agent to a formulated system, you are changing the characteristics of final cured properties. We recommend warming the material to lower the viscosity, not adding a thinning agent. Or please tell us your required viscosity, we would recommend you other suitable resins to try.
4. How can I speed up curing time?
Answer: You can speed up curing time at elevated temperature.
5. How do I get a technical data sheet for your products?
Answer: Please send us your inquiries. We will provide you our TDS immediately.
6. What should I do if a potting compound couldn’t cure?
Answer:
1) Make sure the mixing ratio is exactly correct (by weight)
2) Make sure the compounds are thoroughly mixed. If the resin includes fillers, before use, please stir the resin respectively to uniform the fillers in the resin. After you mix resin and hardener, please scrape the materials attached around the wall and bottom of the mixing container and mix again.
3) The cure rate of the compounds will highly dependent on the potting amount. Curing would be faster in larger potting amount and smaller amount will take longer curing time.
4) If the self life of the compounds are expired and uncured happen, we suggest you not to use the material or contact with us for further recommendation.
5) If the compounds haven’t store around proper conditions, it would also cause uncured. Please refer to our data sheet for suitable store conditions.
7. Should I de-air my materials:
Answer: For most conditions, de-air the compounds are highly recommended. The vacuum should be hold for minutes till the collapse of the foam head while minor bubbling continues and then slowly released.
8. Do I need to use different caulk products for different jobs?
Answer: Yes. Caulks differ in their formulations, and their intended use. Properties like adhesion, flexibility, elasticity, and durability vary substantially from product to product so it is important to select the right product for each job. If you any assist to pick up the most suitable silicone sealant for your application, please don’t hesitate to contact with us. We will be pleased to give you any technical support.
9. Do I need to prepare the surface material before applying silicone caulk?
Answer: It is recommended that you adequately prepare the surface(s) to be caulked as to ensure a tight, strong seal.
