WEST SYSTEM 306-25 Fiberglass & Repair The WEST SYSTEM Model Pump A is a precision metering pump system designed to dispense 105 Epoxy Resin and hardeners at the correct 5:1 ratio by volume. This professional-grade pump set eliminates the guesswork and potential errors of manual measuring, ensuring accurate mix ratios every time for reliable epoxy cure and performance. Accurate 5:1 Metering: This pump system is calibrated to dispense exactly five parts resin to one part hardener with each stroke, matching the required mix ratio for WEST SYSTEM 105 Resin with 205 or 206 Hardeners. Accurate metering is critical for proper epoxy cure—too much or too little hardener can result in soft, tacky, or brittle cures that compromise strength and durability. Eliminates Measuring Errors: Manual measuring with cups and scales introduces opportunities for error, especially in busy shop environments or when working with multiple batches. The Model Pump A delivers consistent, repeatable ratios with simple pump strokes, saving time and eliminating the most common cause of epoxy mixing problems. Professional Efficiency: For boatyards, professional builders, and frequent epoxy users, metering pumps dramatically improve workflow efficiency. Simply pump the required number of strokes into your mixing container, stir thoroughly, and you're ready to work—no measuring, no calculations, no waste from incorrect ratios. Key Benefits: Precise 5:1 Ratio: Calibrated for WEST SYSTEM 105 Resin with 205/206 Hardeners Consistent Results: Eliminates mixing errors for reliable epoxy cure Time Saving: Faster than manual measuring methods Easy to Use: Simple pump strokes deliver accurate ratios Professional Quality: Durable construction for long service life Rebuildable: Can be serviced with rebuild kits for extended use Compatible With: WEST SYSTEM 105 Epoxy Resin WEST SYSTEM 205 Fast Hardener WEST SYSTEM 206 Slow Hardener Important Notes: This pump set is designed specifically for the 5:1 mix ratio. If you're using 207 Special Clear Hardener or 209 Extra Slow Hardener (which require different ratios), you'll need the appropriate pump model for those hardeners. Always verify you're using the correct pump for your hardener choice. Invest in accurate metering for professional-quality results. The Model Pump A ensures every batch of epoxy is mixed correctly, eliminating the most common source of epoxy problems and delivering consistent, reliable performance.

WEST SYSTEM 207-SC 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 1.45 gallon container is ideal for professional operations and large-scale 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. Working Characteristics: Mix Ratio: 3 parts 105 Resin to 1 part 207 Hardener (by volume) Pot Life at 72°F: 22-27 minutes for planning your work Cure to Solid State: 12-18 hours for handling Cure to Maximum Strength: 4-7 days for full performance Minimum Temperature: 60°F for reliable cure 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 Professional Volume: 1.45 gallon for large projects Ideal Applications: Bright-finished wood coating and sealing Clear coating applications requiring natural wood appearance Wetting out and bonding fabrics for smooth finishes Laminating veneers with exposed joints General bonding where clear finish is desired Any application requiring exceptionally clear epoxy 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. Shipping Requirement: NOTE: 207-SB and 207-SC MUST BE SHIPPED VIA TRUCK LINE ONLY. This 1.45 gallon container provides substantial material for professional boatyards and large-scale bright-finish projects where exceptionally clear, moisture-resistant epoxy coating is essential.
