The R.J. Marshall Co. (Southfield, Mich., USA) will feature three product categories at CAMX 2014: and Spraylite lightweight filler system, Spray Granite Advantage granite effect coating and flame smoke retardant additives. Spraylite is a sprayable, lightweight filler system composed of resin-extending lightweight polymeric microspheres. These microspheres can reduce cost, reduce VOC emissions and help improve processing. These microspheres are resilient and reportedly will not break down during mixing. They also are flexible and will elongate while being sprayed though a mix tip, instantly reforming to their spherical form afterward.
The Spray Granite Advantage (SGA) line is an economical granite effect coating filler system designed to be mixed into a clear gelcoat and sprayed behind a clear gel coat or against the mold as a primary wear surface. SGA color granules are made from a UV-stable thermoset polyester resin and ATH (alumina trihydrate) fillers. Featuring more than 50 unique colors and textures, SGA can be used as spray up coating in composite products or as granite effect filler in sheet molding and bulk molding compounding (SMC/BMC).
The flame and smoke retardant additive products include a range of ATH fillers. The Maxfil line is designed for maximum filler loadings, extremely low resin viscosities, increased flame retardance and decreased formulation cost.
