More about this item

WEST SYSTEM 404-45 Fiberglass & Repair

404 High-Density Filler is a premium thickening additive specifically developed for maximum physical properties in hardware bonding and structural applications where high-cyclic loads are anticipated. This 43 oz container provides extensive material for professional operations, large projects, and demanding bonding, filleting, and gap-filling applications requiring maximum strength.

Maximum Strength for Hardware Bonding:

404 is engineered to provide the highest physical properties of any WEST SYSTEM filler, making it the preferred choice for bonding hardware, fittings, and components that will be subjected to high-cyclic loads, vibration, and stress. The dense formulation creates incredibly strong bonds that resist fatigue and failure.

Ideal for High-Load Applications:

When bonding cleats, winches, stanchions, chainplates, and other heavily loaded hardware, 404 High-Density Filler provides the strength and durability needed to withstand repeated loading cycles without degradation. This makes it essential for critical structural bonding applications.

Structural Filleting and Gap Filling:

Beyond hardware bonding, 404 can be used for filleting and gap filling where maximum strength is necessary. The high-density formulation creates structural fillets that can carry significant loads and fill voids without compromising strength.

Dense, Strong Mixture:

The high-density particles create a very strong, dense epoxy mixture that maximizes compressive and tensile strength. While the mixture is slightly heavier than other fillers, the superior strength properties make it worth the minimal weight penalty for critical applications.

Professional 43 oz Container:

This large container provides extensive material for professional boatyards, production facilities, and large-scale projects requiring multiple hardware installations and structural bonding applications. The substantial quantity ensures you have ample filler on hand for demanding work.

Key Benefits:

  • Maximum Strength: Highest physical properties of any WEST SYSTEM filler
  • High-Cyclic Load Resistance: Withstands repeated loading without failure
  • Hardware Bonding: Ideal for cleats, winches, and heavily loaded fittings
  • Structural Applications: Creates strong fillets and gap fills
  • Dense Formulation: Maximizes compressive and tensile strength
  • Off-White Color: Neutral appearance for various applications

Common Applications:

  • Bonding deck hardware (cleats, winches, stanchions)
  • Installing chainplates and rigging attachments
  • Bonding heavily loaded fittings and components
  • Structural filleting requiring maximum strength
  • Gap filling in high-stress areas
  • Any application where high-cyclic loads are anticipated

Mixing Guidelines:

Add High-Density Filler to mixed epoxy resin and hardener gradually while stirring until you achieve the desired consistency. For hardware bonding, mix to a thick, paste-like consistency that completely fills voids around fasteners and provides maximum contact area.

This 43 oz container provides extensive material for professional operations and large-scale projects. When maximum strength is non-negotiable, 404 High-Density Filler is the professional's choice.
