West Systems 4039 Microfibers Epoxy Thickening Additive 6 oz

West Systems 4039 Microfibers is a fine fiber blend designed as a thickening additive for epoxy resins. This off-white filler builds volume quickly and blends easily to create versatile adhesive mixtures, making it especially effective for bonding wood and other porous materials.

Key Features:

• Fine fiber blend for fast volume building and easy mixing
• Creates a multi-purpose adhesive with excellent gap-filling properties
• Maintains superior wetting characteristics when mixed with epoxy
• Ideal for wood bonding applications and structural repairs
• Off-white color for clean appearance on light-colored materials
• 6 oz. container size (24 containers per case)

When added to epoxy resin, West Systems Microfibers create a thickened mixture that retains the adhesive's ability to penetrate and wet surfaces while providing enhanced gap-filling capabilities. This makes it an excellent choice for filleting, bonding large surface areas, and creating strong structural joints in marine, woodworking, and composite fabrication projects.
