A stop-leak composition for the cooling system of an internal combustion engine and the like may comprise a powdered mixture of ground wood, optionally with ginger rhizome powder, with the above being mixed with ground nutshells. The composition may be packaged in polyvinyl alcohol film. Also, a stop-leak composition tablet may be prepared from powdered purified cellulose, ground nutshells, and ginger rhizome powder, formed into a solid tablet. Either of these items may be placed into the radiator of a vehicle. The bag and the tablet each dissolve, and the contents spontaneously disperse into the radiator coolant to seal pin hole leaks.

Stop-leak composition for internal combustion engines

An adhesive coated label can be adherent to untreated polyolefin containers, and can be significantly oil resistant to avoid staining of the label if brought into contact with oil. The label comprises a label body of a clay-reinforced paper. The label body carries an adhesive layer on one side which preferably comprises from 0.3 to 10 weight percent of wood rosin or wood rosin ester, to provide a desired adhesion to polyolefin. A removable backing layer typically covers the adhesive layer before use. The backing layer has a release layer positioned against the adhesive layer, which comprises a silicone resin cross linked by the reaction of Si-H linkages with silanol or silicone-olefin linkages. The release layer may comprise a polypropylene sheet, particularly a polypropylene strip on which many labels are carried, to facilitate the manufacture and storage of the labels.
