Water-based mass hydrophobation of gypsum based on oligomeric propylsiliconate
Scope of Application
Protectosil® MH 10
for the mass hydrophobation of gypsum, reduction of water uptake according to EN 520 >97%
creates an excellent beading effect on the gypsum’s surface
supplied ready to use
creates water vapour permeable, invisible protection
homogeneous distribution of active material in substrate for best performance
improves the thermal insulation and mechanical properties of treated substrates
especially recommended for gypsum boards and other gypsum-based final products
no additional post-treatment necessary
Protectosil® MH 10 is suitable for the waterproofing of gypsum and other construction materials.
Protectosil® MH 10 is used undiluted and is added into the gypsum together with the mixing water. Generally, the amount to be added ranges from 1,0 to 3,0 w% (based on gypsum weight).The exact dosage should be determined in a test.
Protectosil® MH 10 forms an invisible, hydrophobizing protection.
Protectosil® MH 10 will develop its hydrophobic effect during the hardening of gypsum. Depending on the substrate used, allow a curing time of 5 to 14 days before subjecting the treated sample to any performance tests.
