Dow DOWSIL MS-1003 Moldable Silicone A&B Kit

Dow DOWSIL MS-1003 Moldable Silicone A&B Kit is a two-part, room-temperature-curing silicone rubber system from Dow’s DOWSIL MS series. It offers excellent tear strength, flexibility, and dimensional stability for prototyping, mold-making, and low-volume casting. Easy to mix 1:1 by volume, it cures to a durable, translucent elastomer with low shrinkage and good chemical resistance.

Features Of Dow DOWSIL MS-1003 Moldable Silicone A&B Kit

  1. Two-part, room-temperature vulcanizing (RTV) silicone system with excellent moldability and low viscosity before cure.

  2. Self-adhesive to common substrates including plastics, metals, and glass without primer.

  3. Fast handling strength development—tack-free in approximately 30 minutes at 23°C/50% RH.

  4. Excellent flexibility and elongation (>200%) after full cure, enabling dynamic sealing and vibration damping.

  5. UL 94 HB flammability rating and RoHS-compliant formulation for regulated industrial use.

Typical Applications Of Dow DOWSIL MS-1003 Moldable Silicone A&B Kit

  1. Prototyping and low-volume production of custom gaskets and seals for electronics enclosures.

  2. Vibration-damping mounts and isolators in automotive interior components.

  3. Conformal potting and edge-sealing of sensors and PCB assemblies.

  4. Repair and refurbishment of elastomeric parts in medical device housings.

  5. Custom-shaped thermal interface pads where moderate compressibility and dielectric insulation are required.
