Inquiry (采购产品): Thermally conductive coatings Hello, I am a second year materials engineer at cal poly and must say I find ur company website very interesting. That being said I am working on building, for a hot tub, a solar water heater using copper tubing. Would you have a coating or a paint to use for these tubes and possibly the whole apparatus? **** Hidden Message ***** Griffin Beemiller 93405 Company: Cal Poly E-mail: gbeemill@calpoly.edu **** Hidden Message ***** gbeemill@calpoly.edu
