This professional-grade 30 lb bulk container is ideal for boatyards, professional builders, and serious DIY enthusiasts who need the ultimate in bonding strength for critical applications.

Engineered for Maximum Strength:

West System developed 404 specifically for hardware bonding and applications where high-cyclic loads are anticipated.

When blended with epoxy, 404 High-Density Filler creates an excellent gap-filling adhesive and produces incredibly strong structural fillets. The dense formulation bridges gaps reliably while maintaining maximum bonding strength, making it ideal for hardware installations, structural joints, and anywhere that strength is the primary concern.

The Strongest Bond Available:

Use 404 wherever you need an especially strong bond that will stand up to the most demanding marine conditions. Whether you're bonding hardware that will see constant stress, creating structural fillets for critical joints, or filling gaps in high-load applications, 404 delivers unmatched adhesive strength and durability.
