SILRES® BS 38 N

SILRES® BS 38 N is a solvent-based mixture of silane, siloxane and fluoropolymer (< C8). In diluted form, it serves to render inorganic substrates such as mineral construction materials water-repellent and oil-repellent. Unlike conventional impregnating agents, which display only a hydrophobic, i. e. water-repellent, effect, SILRES® BS 38 N also exhibits an oleophobic, i. e. oilrepellent, effect. The pores of the substrate remain open, the water vapour diffusion is hardly affected, if at all. Oil, grease and paint, etc. can be more easily removed from surfaces that have been treated with SILRES® BS 38 N.



Properties

SILRES® BS 38 N performs very well as:

• Treatment of facades of natural or synthetic stone, concrete, or fibrous cement in order to allow easier removal of dirt, grease, graffiti, posters, etc. from monuments, exterior and interior walls.

• Water, oil and dirt repellent treatment of low-porosity natural stone, e. g. marble, travertine and granite.

• Treatment of floors of natural or synthetic stone, or unglazed ceramic tiles for easy care.

• Treatment of window sills and table tops of natural or synthetic stone, or fibrous cement to avoid staining.

SILRES® BS 38 N should be favorably diluted in a product:solvent-ratio 1 : 6 to 1 : 10 (parts by weight). Suitable diluents are white spirit (e. g. White Spirit 130/175 or Shellsol T) and isoparaffins.
Excess should be removed after a few minutes.
A long storing period SILRES® BS 38 N can lead to a deposit. In this case it should be mixed up again. The substrate to be treated should be air dry and absorbent. The diluted solution should be liberally brushed onto substrate. The hydrophobic and oleophobic effects develop within 24 - 48 hours. Because of possible discoloration, it is advisable to carry out tests area. This can also be used to check the efficiency of the products. Substrates treated with SILRES® BS 38 N should be cleaned at once after contamination with oil, grease or paint because paint in particular is very difficult to dissolve once the binder has fully hardened. After cleaning and drying, it is necessary to repeat treatment with SILRES® BS 38 N.
