Shelf life: 12 months.
Skinning time: Skin forms after approximately 20 minutes at 23°C @ 55% RH.
Working time: Approximately 15 to 20 minutes depending on conditions.
Joint design: Please consult the Technical Information Sheet entitled ‘Joint design for cartridge based products’ prior to application.
Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed.
Cut the tip of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun into the joint ensuring good contact with surfaces. In deep joints, the use of Hodgson Backing Rod is essential to ensure good joint formation.
