Silicone resin for large industrial objects: heat resistant and ambient curing

  • Provides excellent color stability
  • Heat resistance up to 650°C
  • Solvent-free product

SILIKOPHEN® AC 1000, from Evonik Resource Efficiency, is a methyl silicone-based resin designed for high-temperature applications of large industrial objects. It is a very economic grade that is suitable for pipelines or industrial plants as well as for fireplaces in the private sector. Its main application is thermostable corrosion protection.

However, these kind of coatings typically require curing at high temperatures that limit their application on large objects. In contrast, SILIKOPHEN® AC 1000 cures under ambient conditions, while maintaining corrosion protection at permanent high temperatures. The high content of alkoxy functional groups, in combination with specific tin-free catalysts, allows the hydrolysis – condensation reaction, and therefore the crosslinking of the system, at ambient temperature.

Due to the resin’s low viscosity, solvent-free formulations can easily be realized. Furthermore, it provides excellent color stability. It has a very high inorganic content and a very low VOC content. Benzene is not produced during the heating phase nor during continuous operation. In addition, smoke generation is reduced to a minimum.

The product complements the existing portfolio of Evonik’s Coating Additives Business Line, so that the right solution is available for every requirement. You can find regulatory, technical, and safety data sheets on SILIKOPHEN® AC 1000 at
