SikaSeal-403 Heat Cement – Professional Fire-Resistant Joint Sealant

SikaSeal-403 Heat Cement is a single-component, sodium silicate-based sealant engineered for high-temperature applications in construction and industrial settings. Designed to withstand extreme heat exposure up to 1250°C, this professional-grade product delivers reliable performance where standard sealants fail.

Key Features & Benefits

Superior Heat Resistance

This heat cement maintains structural integrity at temperatures that would destroy conventional sealants. Ideal for sealing joints in refractory brick installations, fire-rated assemblies, chimney systems, and industrial piping exposed to continuous or intermittent high heat.

Durable Joint Protection

  • Excellent adhesion to masonry, ceramics, and metal substrates
  • Resists thermal cycling and joint movement
  • Prevents moisture and smoke infiltration
  • Long-lasting performance in harsh environments

Professional Application

As a monocomponent product, SikaSeal-403 requires no mixing or special equipment. Apply directly with standard caulking tools for consistent results. Proper substrate preparation and application technique ensure full development of thermal and adhesive properties.

Ideal Applications

  • Fire-rated wall and ceiling penetrations
  • Refractory brick and tile joints
  • Industrial exhaust systems and flue pipes
  • Fireplace and barbecue construction
  • Building envelope fire-stopping
