M30 Methylhydrogen Silicone Fluid is a Methylhydrogen polysiloxane (Polymethylhydrogensiloxane) [CAS No 63148-57-2] with a viscosity in the range of 30cSt @ 25°C. M30 Methylhydrogen Fluid is widely used in waterproofing applications for gypsum board, plasterboard and plaster blocks. M30 is oil-soluble. Most often, it is applied after being diluted with solvents such as acetone. Dilution ratios vary contingent upon the surface to be treated.
The curing temperature of M30 Methylhydrogen Silicone ranges from 120°C to 175°C. Cure times are accelerated at higher temperatures. For example, the cure times of uncatalyzed M30 is approx 3 to 4 hours at 120°C. At 150°C, cure times are between 10 to 15-minutes. Catalysts that accelerate cure times include zinc octate, iron octate, dibutyl tin dlaurate & tin octoates. A typical concentration is 10-parts of Methylhydrogen to 1-part catalyst. Note: Clearco does not provide catalysts.
Applications include: waterproofing gypsum board, waterproofing plasterboard, waterproofing plaster block.
