SILRES® REN 80
SILRES® REN 80 is a medium hard methyl phenyl silicone resin supplied as 82 wt.%-solution in xylene.
Typical application of SILRES® REN 80 is the use as binder for heat-resistant anticorrosive coatings.
特性
SILRES® REN 80 offers the following properties:
- Silicone resin with medium molecular weight
- very good balance of flexibility, hardness, heat resistance and tack-free air drying at room temperature
- high solids resin offering more coating formulation options
- high viscosity
- medium hardness
- compatibility with organic resins (but preferably used as a sole binder)
- excellent hydrophobicity and corrosion-protection
数据表
SILRES® REN 80 is mainly used as binder for coatings. It combines outstanding heat resistance and weatherability, dries to tack-free film at ambient temperature.
Heat-resistant Coatings
SILRES® REN 80 is especially suitable for all kinds of heat-resistant paints. At 82 wt.% solids it is offering more degrees of freedom to the coating formulator than 50 wt.% solutions. 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® REN 80 in combination with suitable temperature stable pigments and fillers can achieve thermal stability up to 650°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® REN 80 dry at room temperature to tack-free films which already provide temporary corrosion protection. A initial baking step at 200°C/1h has proven to effectively reduce the risk of cracking at extreme temperatures. The coating films will develop their final properties only after prolonged exposure to temperatures > 400°C.
Formulation examples are available on request.
Information on the current BfR/FDA-status is available on request.

储存
SILRES® REN 80 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.
