WEST SYSTEM WEST SYSTEM Colloidal Silica 10 lb #406-B $381.46 $476.10
WEST SYSTEM 406-B Fiberglass & Repair 406 Colloidal Silica is the most versatile epoxy thickening additive in the West System lineup, engineered to give you precise control over epoxy viscosity for a wide range of marine repair and construction applications. This professional-grade 10 lb bulk container provides exceptional value for boatyards, serious DIYers, and contractors who demand consistent, reliable performance. Superior Thickening Performance: When blended into epoxy resin, 406 Colloidal Silica transforms liquid epoxy into a non-sagging paste that stays exactly where you apply it. This makes it ideal for vertical and overhead joints where runoff would otherwise be a problem. The smooth, creamy consistency spreads easily and creates professional-quality bonds and fillets without voids or air pockets. Exceptional Strength & Versatility: Unlike lightweight fairing fillers, 406 is a high-strength structural additive that creates incredibly strong bonds and fillets. It's the go-to choice for general epoxy bonding, filleting, and any application where maximum strength is required. The smooth mixture it produces is easy to work with and finishes beautifully. Key Applications: Structural Bonding: Creates maximum-strength adhesive bonds for critical joints Filleting: Produces smooth, strong fillets for tabbing bulkheads and reinforcing corners Gap Filling: Fills voids and gaps without sagging or running Fairing Compound Enhancement: Blend with lightweight fillers to improve strength, abrasion resistance, and workability Vertical & Overhead Work: Prevents epoxy runoff on challenging surfaces Enhanced Fairing Compounds: One of 406's most valuable features is its ability to improve other fillers. When combined with lightweight fairing compounds, it significantly increases their strength, abrasion resistance, and workability, resulting in a tougher, smoother surface that's easier to sand and finish. Universal Compatibility: 406 Colloidal Silica blends seamlessly into WEST SYSTEM 105 Epoxy Resin with any 200 Series Hardener, G/flex Epoxy 650, or G/5 Five-Minute Adhesive, giving you maximum flexibility across your entire epoxy toolkit. Whether you're building, repairing, or reinforcing, 406 Colloidal Silica delivers the strength, versatility, and ease of use that marine professionals rely on for critical applications.

WEST SYSTEM WEST SYSTEM Slow Hardener 11.31 Gallon #206-E $1,105.83 $1,326.99
WEST SYSTEM 206-E Fiberglass & Repair 206 Slow Hardener is a medium-viscosity epoxy curing agent designed for use with WEST SYSTEM 105 Resin when you need extended working time for complex laminating, large coating areas, or detailed assembly work. This 11.31 gallon bulk container is designed for large-scale professional operations, production environments, and high-volume users who need reliable, slower-curing epoxy performance. Extended Working Time: With a pot life of 20-25 minutes at 72°F, 206 Slow Hardener provides significantly more working time than 205 Fast Hardener. This extended open time is invaluable when you need extra time to wet out large fabric areas, position complex assemblies, apply smooth coatings, or work in warmer shop conditions where faster hardeners would cure too quickly. High-Performance Properties: When mixed with 105 Epoxy Resin at the proper 5:1 ratio (five parts resin to one part hardener), the cured mixture yields a high-strength, rigid, moisture-resistant solid with excellent bonding and coating properties. The result is a durable epoxy system suitable for demanding structural applications and protective coatings. Bulk Volume for Professional Operations: The 11.31 gallon bulk container is designed for professional boatyards, production facilities, and large-scale operations where high-volume epoxy use demands economical bulk packaging. This size reduces packaging waste and provides cost savings for frequent users. Key Benefits: Extended Pot Life: 20-25 minutes at 72°F for ample working time High Strength: Creates rigid, structural bonds and coatings Moisture Resistant: Excellent protection in marine environments Medium Viscosity: Easy to mix and apply Versatile: Suitable for bonding, coating, and laminating Bulk Volume: 11.31 gallon for high-volume professional operations Ideal Applications: Large-area laminating requiring extended wet-out time Coating applications needing smooth, even coverage Complex assemblies requiring careful positioning Working in warmer shop temperatures Structural bonding and laminating Production environments and professional boatyards Working Characteristics: Mix Ratio: 5 parts 105 Resin to 1 part 206 Hardener (by volume) Pot Life at 72°F: 20-25 minutes Cure to Solid State: Longer than 205 Fast Hardener Minimum Temperature: 60°F for reliable cure This 11.31 gallon bulk container provides exceptional value for professional operations and high-volume users who rely on the extended working time and reliable performance of 206 Slow Hardener for efficient marine construction and repair work.

WEST SYSTEM WEST SYSTEM Model Pump A 5/1 Ratio #306-25 $579.47 $723.25
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.
