Physical and Chemical Properties

  • Melting Point = 90-100 C

Working Properties

  • Easiest application is to stick a hot soldering needle into the powder and then apply the melted polyamide.
  • An alternative consists of melting the polyamide powder with an iron between two sheets of silicone coated polyester film, in order to obtain a coat of approx. 1-2 mm thickness. After cooling, the polyamide coat is cut in very thin strips. These strips are then used together with the soldering needle to weld the threads.
