FEATURES
Emulsion SE-50/12 – water emulsion of oligodimethylhydroxidesiloxane, designed for water-repellency treatment of various materials, including glass fiber and mineral wool products treated with phenol-formaldehyde resin.
APPLICATIONS AND ADVANTAGES
Fiberglass mats or mats of mineral wool manufacturing:
- Hydrophobisation
- Preventing the formation of fine dust during the prcessing
- Human health protection from the harmful effects of dust
- Accelerates and simplifies installation

COATING
The emulsion SE-50/12 or the mix of emulsions SE-50/12 and ME-50/42 is applied together with a binder by spraying method.
The amount of the emulsion SE-50/12 or of the mix of emulsions SE-50/12 and ME-50/42 depends on the required water-repellency properties of the final product, so there is no general advice on how to use. The necessary amount can be determined after individual test. In most cases the introduction of at least 0,2% of the emulsion SE-50/12 or 0.6-1.2% of the mix of emulsions SE-50/12 and ME-50/42 from the weight of the dry fibrous material is enough.
ADDITIONAL INFORMATION
- To prevent the formation of fine dust in the production of glass fiber mats or mats of mineral wool, use the emulsion SE-50/12 in combination with ME-50/42.Mixing ratio is 1 part by weight of emulsion SE-50/12 for 3-5 parts by weight of emulsion ME-50/42. In this case, a mixture of emulsions also mixed with a solution of phenol aldehyde resin and other additives.
- To make glass fiber mats or mats of mineral wool water resistant, mix the emulsion SE-50/12 with a solution of phenol aldehyde resin and other additives.
- Since the shelf life of various mixtures mainly depends on the composition of phenol aldehyde resins and additives, it is impossible to give any general advice on their compatibility.
- The emulsion SE-50/12 or the mix of emulsions SE-50/12 and ME-50/42 is used in combination with the binder.
- The treatment of glass wool and mineral wool with the emulsion SE-50/12 or with the mix of emulsions SE-50/12 and ME-50/4″ after drying and curing is not recommended.
SAFETY INFORMATION
The information on safety you can find in safety data sheet, provided by our sales department on request.
STORAGE
The shelf life of the emulsion SE-50/12 is 6 months from the date of manufacture. Store at temperature from+5°C to +30°C in tightly closed containers of manufacturer in covered warehouses, protected from moisture, direct sunlight and away from heaters and tanks with strong oxidizing agents, alkalis and acids.
The user may choose to use the product after the expiration of shelf life period and the quality is checked to meet technical requirements of “Water repellency emulsions”.
