407 Low-Density filler is a blended microballoon-based filler used to make fairing putties that are easy to sand or carve. Reasonably strong on a strength-to-weight basis. Cures to a dark red/brown color. |
A pure white, hollow glass bubble based, low density filler designed for fi lling and fairing of fibreglass.When the filler is mixed with WEST SYSTEM epoxy at a ratio of 10% to 25% by weight, it creates a smooth creamy paste for filling and fairing over glass fibre repairs. The cured epoxy/fi ller is very easy to sand. Being white in colour the cured epoxy fi ller mix will be hidden easily behind paint or polyester gelcoat but must be protected by further coats of epoxy if used below the waterline. |
410 Microlight is the ideal low-density filler for creating a light, easily-worked fairing compound especially suited for fairing large areas.Microlight mixes with greater ease than 407 Low-Density filler or microballoons and is approximately 30% easier to sand. It feathers to a fine edge and is also more economical for large fairing jobs. Not recommended under dark paint or other surfaces subject to high temperatures. Cures to a tan color. |
