Product Applications

Particular advantages are observed with water-based systems. It is an essential ingredient in products obtained in many industries:

  • mineral wool - insulating material;
  • fiberglass / fiberglass composites - as a component and / or decoration;
  • primer for glass and metals;
  • abrasives: as an additive to a phenolic binder;
  • molding resins: as an additive to cold curing phenolic and furan resins;
  • sealants and adhesives: as a primer or additive to improve adhesion on glass, metals and plastics.

Examples of suitable inorganic substrates:
glass, fiberglass, glass wool, mineral wool, quartz, sand, cristobalite, vopastonite, mica, aluminum trihydrate, magnesium dihydrate, kaolin, talc and other silicate fillers, mineral surfaces, metal oxides and metals.Can be used with polymers such as epoxy, phenolic, furan, melamine resins, polyurethanes, polyamides, polybutylene terephthalates, polycarbonates, EVA, modified polypropylenes, PVA, acrylates and silicones.

Product Properties

Acts as a promoter of adhesion between inorganic materials (e.g. glass, metals and fillers) and organic polymers (thermoactive, thermoplastic and elastomers).
The use of Unisil MSO-AW improves the following properties of the resulting materials:

  • mechanical properties such as impact strength, flexural and tensile strength;
  • moisture resistance;
  • anti-corrosion properties;
  • technological properties: adhesion, better filler dispersion.
