Features Of Dow DOWSIL FC-5004 DM Silicone Resin Gum

  1. High-molecular-weight methyl-phenyl silicone resin gum offering exceptional thermal stability and oxidative resistance.

  2. Self-adhesive and tacky at room temperature, enabling direct incorporation into silicone elastomer and coating formulations without additional tackifiers.

  3. Excellent compatibility with polydimethylsiloxane (PDMS) polymers and silicone fluids, facilitating homogeneous blending in high-viscosity systems.

  4. Provides enhanced mechanical reinforcement and improved tear strength when compounded into high-performance silicone rubbers.

  5. Solvent-free, 100% reactive silicone resin gum — supports low-VOC and environmentally compliant formulation strategies.

Typical Applications Of Dow DOWSIL FC-5004 DM Silicone Resin Gum

  1. High-temperature resistant silicone elastomers for automotive gaskets and under-hood sealing components.

  2. Thermal management materials including thermally conductive gap fillers and potting compounds.

  3. Release coatings for high-release-demand applications such as specialty paper and composite mold liners.

  4. Reinforcing additive in liquid silicone rubber (LSR) formulations for medical-grade and food-contact parts.

  5. Base resin for heat-curable silicone coatings used in industrial protective and electrical insulation applications.
