404 High Density

ADHESIVE FILLER

404 High-Density Adhesive Filler is an epoxy thickening additive. We developed it for maximum physical adhesive properties in hardware bonding, or anywhere that high-cyclic loads are anticipated. Blended with epoxy, it makes an excellent gap filler or structural fillets. Use this filler wherever you need an especially strong bond. You can blend it into any WEST SYSTEM 105 Resin/200 Series Hardener combination, G/Flex Epoxy 650, or G/5 Five-Minute Adhesive.

Designed for:

  • Wood Bonding
  • Adhesion
  • Gap Filling

Thickening

Modifying with fillers and additives makes WEST SYSTEM epoxy extremely versatile for a wide variety of bonding and coating applications. Epoxy can be thickened to the ideal consistency needed for a particular job. Epoxy thickened with adhesive (high-density) fillers strengthens structural bonds, bridges gaps, and fills voids. Epoxy thickened with fairing (low-density) fillers is easily sanded and shaped after it cures.

Bonding with Fillets

Epoxy fillets can make a bond between components even stronger than the components themselves, ensuring that loads can be transferred between structures and panels effectively, with no risk of stress fractures or other structural issues.
