Product Description

Special Features:

This product is a hydroxyxohide polymer or a fluorosiloxane and a silicide cluster.

  • Low Surface Energy: Trifluoropropyl groups ensure ultra-low surface tension and superior oil repellency (oleophobicity) over standard silicone oils;
  • Chemical Shielding: Side-chain fluorination protects the siloxane backbone, providing elite resistance to fuels, solvents, and harsh reagents;
  • Thermal Range: Maintains structural integrity and oxidative stability from -60°C to +250°C;
  • High Dielectric Performance: Reliable electrical insulation with a high dielectric constant and low loss, even in humid or corrosive conditions.

Applications

  1. Anti-Structuring Agent: Acts as a high-efficiency structural controller for Fluorosilicone Rubber (FSR), preventing “crepe hardening” during storage and improving processing consistency.
  2. RTV Base Polymer & Diluent: Serves as the primary reactive polymer or viscosity modifier for condensation-cure, Room Temperature Vulcanizing (RTV) fluorosilicone systems.

Application Scenarios

Power Generation & Nuclear Construction & Infrastructure Oil, Gas & Marine

Packaging & Handling

In 5kg, 25kg and 250kg drum

Keep in cool, dry and ventilated place. This product should be neutral to avoid contact with acidic and alkaline substances. Keep in unopened containers, shelf life is 12 months from the date of production. It is shipped as non-hazardous substance.

Storage beyond the shelf life 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.
