Hercules Chemical Co. was granted a U.S. patent for its professional grade stain-free polymer sealant, Sta Put® Ultra™. Unlike other plumbers’ putty, Sta Put Ultra is oil free, non-staining, and can be used on porous surfaces such as stone, marble, granite, plastic, rubber and fiberglass without pre-treatment. It handles just like any other putty, can be easily molded as needed, and remains permanently soft, malleable and flexible.  It is clean to handle, odorless, non-toxic and will not melt, rot, crumble, dry out or shrink, even when used in contact with porous surfaces such as wood or concrete.

Sta Put Ultra is available in convenient 14 oz packages and can be ordered through OateySCS ( www.oateyscs.com).
