Other special specifications can be customized after confirmation.
Properties
(1) Water-repellent treatment of plaster
OSi HOSil fluid is usually added by hydrocarbon solvents like acetone, and methyl ethyl ketone to be mixed with the plaster preparation.
Good water-repellent properties are obtained by adding a dilute solution of OSi HOSil to the plaster powder. The adding ratio is related to the kind of plaster, the H content of OSi HOSil, the water/gypsum ratio, and additives such as starch/cellulose or surfactants. This is why no general recommendations on the dosage of OSi HOSil can be given.
Coating of OSi HOSil dilution solvent is usually heat cured to develop release properties or water repellency. Curing temperatures range from 120℃ to 175℃. Curing times are much shorter at higher curing temperatures.
Catalysts are often used to accelerate cures. Four suitable catalysts in order of increasing activity include Zinc octoate, iron octoate, dibutyl tin dilaurate, and tin octoates.
The actual curing time will vary with the surface being treated as well as with the catalyst.
