PVCu Activator is designed to work in conjunction with AlphaChem high viscosity superglue to create a rapid, high-strength bond in just 10 seconds. This activator is ideal for use on PVC, PVCu, and various plastics, as it will not yellow over time. It is also suitable for use on rough and vertical surfaces. Additionally, the product does not contain harmful compounds such as Chlorofluorocarbons or Methylene Chloride. However, excessive use may cause discoloration on PVCu surfaces, so it is recommended to conduct a patch test on a hidden area if discoloration is a concern.
