SILRES® KX is a medium-molecular weight methyl silicone resin supplied as 50 wt.%-solution in xylene.

Typical application is the use as binder for high heat-resistant coatings.


SILRES® KX offers the following properties:

  • good balance of flexibility, hardness, heat resistance and curing speed
  • very low viscosity
  • air-drying
  • limited compatibility (preferably used as a sole binder, compatibility typically exists only with other methyl silicone resins)
  • excellent hydrophobicity and corrosion-protection 

SILRES® KX may be used as a binder for coatings. It combines outstanding heat resistance and weatherability, dries tack-free and can be heat-cured. It is especially suitable for highly-filled coatings.


Heat-resistant Coatings
SILRES® KX is suitable for all kinds of heat-resistant paints. It is an excellent choice for (anti-corrosion) coatings on fireplaces, mufflers, exhaust systems, engine parts, boilers, furnaces, ovens and oven inserts, chimneys, barbeques, electric/gas heaters, incinerators.

High-heat resistant coating formulations with SILRES® KX in combination with suitable temperature stable pigments and fillers can achieve thermal stability up to 600°C (1100°F) . Aluminum pigments can be used for silver/grey colors and black pigments like iron managnese oxides or copper chromite black spinels for dark black coatings. Platelet-shaped inorganic fillers/extenders like mica or talc are suitable for such formulations. The pigments and fillers must be properly dispersed in the paint. Degreasing/Cleaning and sandblasting of the substrate are recommended for obtaining optimum corrosion resistance and heat stability on metal surfaces. The adhesion will always depend on the specific coating formulation, too. Coating application can be done by spraying, dipping and brushing.

Coatings made with SILRES® KX dry at room temperature to tack-free films which already provide temporary corrosion protection. Especially aluminum pigments accelerate the drying process. Such coating films are not resistant to solvents, however, and have to be heat-cured above 150°C. We propose 200°C/1h as a guideline for aluminum-pigmented coating forumlations to develop optimum mechanical properties and resistance to solvents.

SILRES® KX must be stored in tightly closed original containers with exclusion of moisture. Contact with tin (e.g. with improper metal containers) or moisture will cause gelation. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
