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.
