WoodSeal TM

Wood Seal™

Wood Seal™ is an application ready, water based fire retardant designed for treatment of raw wood. Wood Seal™ is mix of proprietary ingredients, which forms a slight intumescent foam layer and carbon char when the treated wood is exposed to fire. Once the carbon char is formed there will be minimal flame propagation, smoke evolution or afterglow. The product is designed for interior use as well as exterior in certain circumstances.

Fire Retardant Feature
Technical Characteristics

  • Water-based fire retardant penetrant.

  • Designed for use on select types of soft wood.

  • Colorless, non-staining, inert, and low odor

  • The proprietary active ingredients of this product contribute to flame resistance by:  Melting below flaming temperatures and then re-solidifying into a crystalline form of a carbon (char) that acts as a barrier between the paper or paperboard surface and the flame. Forming an intumescent foam barrier when exposed to flame.


Advantages and Performance Characteristics​

  • Aqueous solution containing a blend of proprietary active ingredients.

  • No polybrominated diphenyl ethers are in the composition.

  • Decrease fire and smoke evolution, providing resistance to flameless combustion, referred to as afterglow.

  • Properly applied to wood, when exposed to heat and flame, Wood Seal™ initially form intumescent carbon foam followed by the creation of a carbon char that resists fire, heat, and smoke.

Fire Retardant Benefits

  • Free of PBDE’s and Non-Toxic.

  • Non-staining.

  • Reduces the effect of Heat and Smoke without Flame propagation.

  • Easy and Flexible Product Applications.

  • No Halogen Donor Required.

Testing Certifications

  • ASTM E-84

  • Class B

  • Flame Spread = 35

  • Smoke Generation = 130
