Fillers help expand epoxy's versatility by altering its consistency for specific applications. Each filler possesses a unique set of physical characteristics, but they can be generally categorised as either Adhesive (high density) or Fairing (low density). Adhesive filler mixtures cure to a strong, hard-to-sand plastic suitable for structural applications like bonding, filleting and hardware bonding. Fairing filler mixtures cure to a light, easily sandable material that is generally used for cosmetic or surface applications like shaping, filling and fairing. 410 Microlight is the ideal low-density filler for creating a light, easily-worked fairing compound especially suited for cosmetic or surface applications like shaping, filling or fairing. 410 Microlight mixes to a very smooth creamy texture that can be trowelled to a feather edge, and is less porous than other filling compounds
