                                        How to use

                                          Clean surfaces with solvent-based (non-CFC), general purpose surface cleaner LOCTITE® SF 7070 to ensure surfaces are free of dirt, dust, oil and any other contaminants. Allow to dry.

                                          Cut nozzle at 45° angle to create the proper bead diameter for your application. The appropriate bead diameter is dependent on the gaps that need to be filled, but it is best to start small and increase bead size if necessary. Typical bead sizes range from 1/8” to 1/4”. Screw cut nozzle onto tube for application.

                                          Hold package at a 45° angle and apply a continuous bead at the joint interface.

                                          Clean up any excess or squeeze-out.

                                          RTV silicone sealants cure on exposure to moisture in the air. Typical skin-over time is 60 minutes and full cure time is 24 hours, but times will vary with temperature, humidity and gap.

                                        FAQ

                                          LOCTITE® SI 593 BLACK becomes tack free in about 60 minutes and achieves full cure in approximately 24 hours, based on a 1/4" diameter bead at 72°F.

                                          LOCTITE® SI 593 is ideal for applications requiring an elastomeric sealant, including the sealing of oven flues, flue collars, glass meter covers, making noise dampening pads, bonding flexible rubber materials, weatherproofing ventilation units, and dressing gaskets.
