Lascaux 4040 – Textile Welding Powder 500g


Lascaux 4040 – Polyamide Textile Welding Powder is a Thermoplastic Copolymide Resin used for  textiles and leather, and is widely used for conservation, such as for tear-mending of paintings on canvas. It has a melting point of 90-100°C.

The Textile Welding Powder is a hot-melt adhesive. The easiest way of application is to stick a hot soldering needle into the powder and then apply the melted polyamide.

Another method is by 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 which are then used together with the soldering needle to weld threads.
