Curing rate: Full cure 3 – 5 days depending on thickness, ambient temperature and humidity. Lower temperatures and high humidity will result in a slower rate of cure. Shelf life: 12 months Skinning time: Skin forms after approximately 7 minutes at 23°C @ 55% RH. Lower temperatures and high humidity will result in skinning times being increased. Working time: Approximately 5 minutes.
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.
Tooling: Tool immediately after sealant has been applied within the working time for the product.
