FEATURES
Emulsion ME-50/42 (OE-50/42)* – water emulsion of mineral oil, intended for dust removal and optional water repellent treatment of various materials, including fiberglass and mineral wool products treated with phenol-formaldehyde resin.
APPLICATIONS AND ADVANTAGES
-
- For prevention of formation fine-dispersed dust and for the purpose of giving water-repellent properties for glass fiber mats or mats from silicate cotton the emulsion “ME-50/42” is mixed with solution of phenol-aldehyde resin and other additives. As shelf life of various composite materials depends to a large extent on composition of phenol-aldehyde resin and additives, it is impossible to give a general reference concerning their compatibility.
- The emulsion “ME-50/42” is used jointly with application of binder.
- Treatment of glass wool and silicate cotton by the emulsion “ME-50/42” after drying and hardening is deprecated.
- For increase in water-repellent properties it is recommended to use in composite with emulsion “SE-50/12”.

COATING
The emulsion ME-50/42 is applied together with a binder by spraying method.
The amount of the emulsion 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 0,6-1,2% of the emulsion from the weight of the dry fibrous material is enough.
ADDITIONAL INFORMATION
To prevent the formation of fine dust in the production of fiberglass 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 enhance the water-repellency effect use mixed with the emulsion SE-50/12.
Since the shelf life of various mixtures mainly depends on the composition of phenol aldehyde
resins and additives, it is difficult 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 are used in combination with the binder.
The treatment of fiber wool and mineral wool with the emulsion SE-50/12 or with the mix of emulsions SE-50/12 and ME-50/42 after drying and curing is not recommended.
