More about this item

WEST SYSTEM 207-SE Fiberglass & Repair

207 Special Clear Hardener is specially developed for use with WEST SYSTEM 105 Resin in coating applications where an exceptionally clear, moisture-resistant, natural wood finish is desired. This 17.34 gallon bulk container is designed for large-scale professional operations, production environments, and major bright-finish projects requiring substantial quantities of clear-coating epoxy.

Exceptionally Clear Finish:

207 cures to a light amber color similar to traditional spar varnishes, providing a warm, natural appearance that enhances wood grain without the yellowing or cloudiness that can occur with other hardeners. This clarity makes it the preferred choice for bright-finished wood applications where the beauty of the wood is the focal point.

UV Inhibiting Additive:

A UV inhibiting additive improves the resistance of the 105/207 mixture to sunlight degradation, providing better protection than standard epoxy formulations. However, the cured epoxy surface will still require the additional protection of a quality UV-filtering varnish for long-term durability and appearance in direct sunlight exposure.

Self-Leveling for Smooth Finishes:

207 is formulated to self-level, flowing out smoothly to create glass-like finishes without brush marks or surface irregularities. This self-leveling property also makes it excellent for wetting out and bonding fabrics, ensuring complete saturation and smooth, professional results.

Versatile Performance:

Beyond clear coating, 207 provides good physical properties for general bonding applications and is particularly useful for laminating veneers where bleed-through at joints may be exposed to sunlight. The clear finish and UV resistance make it ideal for applications where both appearance and durability matter.

Key Benefits:

  • Exceptionally Clear: Light amber color enhances natural wood beauty
  • UV Inhibitor: Improved sunlight resistance over standard epoxy
  • Self-Leveling: Flows smoothly for glass-like finishes
  • Moisture Resistant: Excellent protection for wood surfaces
  • Natural Appearance: Similar to traditional spar varnishes
  • Bulk Volume: 17.34 gallon for large-scale professional operations

Ideal Applications:

  • Large-scale bright-finished wood coating and sealing
  • Production environments requiring clear coating
  • Clear coating applications requiring natural wood appearance
  • Wetting out and bonding fabrics for smooth finishes
  • Laminating veneers with exposed joints
  • Professional boatyards and production facilities

Working Characteristics:

  • Mix Ratio: 3 parts 105 Resin to 1 part 207 Hardener (by volume)
  • Pot Life at 72°F: 22-27 minutes
  • Cure to Solid State: 12-18 hours
  • Cure to Maximum Strength: 4-7 days
  • Minimum Temperature: 60°F for reliable cure

Important Notes:

Note the 3:1 mix ratio—this hardener requires a different ratio than 205 or 206 hardeners, so verify you're using the correct metering pumps or measuring method. While 207 contains UV inhibitors, always protect the cured epoxy with a quality UV-filtering varnish for long-term outdoor exposure.

This 17.34 gallon bulk container is designed for professional boatyards, production facilities, and large-scale operations where exceptionally clear, moisture-resistant epoxy coating is essential for high-volume bright-finish work.
