摘要:
An aqueous coating composition for reducing friction and/or blocking at a surface, said composition comprising a solid lubricant and a modified or synthetic clay mineral having thickening properties such that a 2% by weight aqueous dispersion of the modified or synthetic clay mineral thickener has a viscosity of at least 1000 mPa·s. Preferred clay minerals used as thickeners are preferably smectite clays such as saponite, hectorite, stevensite, sauconite, bentonite, beidellite, nontronite, or montmorillonite.
摘要:
A stable and highly productive method for the preparation of silicone foam having uniform cells characterized by mixing the base and curing agent portions of an organosiloxane, along with a gas-containing hollow filler in a mixing device having a shear-stirring mechanism such that the organosiloxane begins to foam and cure when the shear-stirring mechanism is used to rupture the filler and mix the base and curing agent portions.
摘要:
The present invention relates to a process for producing a molded silicone rubber sponge by filling a sponge-forming silicone rubber composition into a cavity of a mold, wherein after the aforementioned sponge-forming silicone rubber composition is cured, and before mold opening of the aforementioned mold, gas present in the aforementioned cavity is discharged. Thereby, a molded silicone rubber sponge without damage such as chips or the like can be effectively produced.
