Sylmasta AB Rapid 5 Minute is a fast-setting, hard-wearing, ceramic-filled repair putty with multiple uses in manufacturing & maintenance.  The hand-kneadable consistency eliminates drips and runs, facilitates adhesion to the substrate, and allows the material to be shaped and formed as needed before curing begins.  Once cured, it can be tapped, drilled, screwed, sawed, machined, ground, filed, or painted.

Suitable for interior or exterior use, Sylmasta AB is resistant to water, chemicals, and temperature extremes. It contains no solvents or VOC’s, is non-flammable, releases no noxious fumes and it won’t shrink or pull away when setting. The unused portion stays fresh for future use when saved in its original package.
