Product Highlights
  • Reduces the water absorption of mineral wool insulation, thus improving their performance characteristics;
  • to prevent the formation of fine dust during fibreglass or mineral wool production it is recommended to use the emulsion se 50-12l mixed with the emulsion oe 50-42;
  • the mixture of emulsions OE 50-42 and SE 50 12L reduces the harmful effects of dust on the human body during contact with mineral wool.

Applications & Uses

Applicable Processes
Precautions for Use

As the shelf life of various mixtures depends on the content of binder and additives, no general advice on their compatibility can be given; Always test the selected concentration of SE 50-12L or mix of emulsions ОE 50-42 and SE 50-12L on the trial sample to determine the optimal amount of material and the suitability for use in a particular case.

Areas of Application

Finishing and hydrophobization of various materials, in particular materials from fiberglass and mineral wool products. To prevent the formation of fine dust it is recommended to be used together with the emulsion OE 50-42.

Application Methods
  • SE 50-12L is applied by spraying together with binder and other additives.
  • When application of the emulsion SE 50-12L together with the emulsion OE 50-42 the mixing ratio is one weight part of the emulsion SE 50-12L for 3 - 5 weight parts of the emulsion OE 50-42. The mixture of emulsions is applied by spraying together with binder and other additives. Reprocessing of fiberglass and mineral wool products after curing of the emulsion SE 50-12L or mix of emulsions OE 50-42 and SE 50-12L is not recommended.
  • The amount of applied emulsion SE 50-12L or mix of emulsions OE 50-42 and SE 50-12L depends on the desired properties of the end product, so no general advice can be given. To determine the optimal amount please provide individual tests. Normally, the sufficient amount of emulsion SE 50-12L is at least 0,2 % or (0,6 - 1,2) % for mix of emulsions OE 50-42 and SE 50-12L by weight of dry fibrous material.
