摘要:
An abrasion-concealing agent for glass containers, which comprises (A) a polyorganosiloxane and (B) a volatile polydimethylsiloxane, a glass container in which abrasions on the surface thereof have been concealed by the abrasion-concealing agent, and a method for concealing abrasions on a glass container by using the abrasion-concealing agent. The abrasion-concealing agent has excellent abrasion-concealing properites, film strength, water resistance, safety, workability and resistance to an aqueous alkaline solution washing, and does not cause any damage to labels on glass containers in the coating process.
摘要:
A continuous method for cleaning and/or removing liquid from industrial parts that includes contacting the part with a cleaning or rinsing composition that contains a straight chain or cyclic polyorganosiloxane.
摘要:
A cleaning composition comprising at least one low molecular weight polyorganosiloxane selected from the group consisting of straight chain polydiorganosiloxane represented by a general formula: ##STR1## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and 1 is an integer from 0 to 5), and cyclic polydiorganosiloxane represented by a general formula: ##STR2## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and m is an integer from 3 to 7). To use it as a water system cleaning agent, polyoxyalkylene group containing polyorganosiloxane, a surfactant, and water are additionally mixed. Accordingly, a cleaning effect free from environmental destruction and contamination, equivalent to flon containing cleaning agents, and satisfactorily stable in terms of dispersion as a water system cleaning agent can be obtained. In addition, to use as a dewatering cleaning agent, the low molecular weight polyorganosiloxane is additionally mixed alone or with a surfactant and/or a hydrophilic solvent. Accordingly, cleaning and water substituting properties equivalent to flon containing dewatering cleaning agents and environmental safety can be obtained.
