Application Information

To facilitate handling, Rubex 126 is extruded onto removable release paper backing. For most efficient usage, ensure all involved surfaces are clean and dry, although light films of lubricant on unpainted metals should not adversely affect performance. Once ready for application, it is recommended that the material be pressed onto one surface, stripped of its paper backing, and then brought into contact with the second surface. When using to seal applications involving fasteners, position on the entry side to prevent the penetration of contaminants through fastener holes.

Packaging & Handling

Rubex 126 is available in a variety of different widths, thicknesses, and profiles. It is manufactured in both roll form, and in customer specified strips. No special handling is required for this product, though storage in a cool, dry area is recommended for maximum shelf life and effectiveness. Tools and equipment used while applying Rubex 126 can be cleaned using mineral spirits, if necessary.

Safety Instructions

No special requirements are needed. An MSDS is available upon request.
