Featherlite FL4005S is a concentrated blend of thermoplastic microspheres and calcium sulfate combined with an effective dust suppressant. Featherlite is ideal for weight, (up to 25%) and cost reduction, in both neat and filled resin systems. These low dust formulations are designed for the products to be used in areas where dust sensitivity is a priority while improving product wet out and lowering resin demand. May also be used for barrier coat filler, or as a light weight putty filler. |
