Fillers, Extenders, and Additives
 

Calcium Carbonate- Used by marble-manufacturers and builders as grout and marble repair when mixed with resin. Also used as a thickening agent in figurines. Available in 200 and 325 mesh.

Imported Talcum- High-whiteness filler. Easy to sand and clean finished products made from mixing talc and resin. Talc powder is also be used to cool the skin.

 
 

Stop Sag- a Thixotropic agent used in the polyester resin, rubber, paint and ink industries to reduce prevent the settling of fillers and pigments. Paint and resin sag is minimized when applied on vertical surfaces. Stop sag is used in the rubber industry to decrease product weight. Use up to 3% by resin weight. Sold in 100gm., 1kg and 10kg.

Marblemite- Calcium carbonate filler especially designed for use in cultured marble. Marblemite is used in figurine casting for translucency and whiteness. It comes ready to use with the proper combination of coarse and fine particles. Putties, caulks, floor tile, cast rigid or elastomeric compounds are filled/extended with Marblemite.

 

Aluminum Hydroxide- Translucent filler used in synthetic granite and marble. Used with flame-sensitive cast resin items such as fireplace appliqués, candle holders, lamp stands, light bulb casing, etc.

 
 

Micro-mix- Engineered reinforcing fillers, Micro mix reduces product weight  and resin consumption yet improves product strength and fire retardance. Used in FRP for increased rigidity. Also mixed in synthetic granite, FRP furnishings, and cement to reduce weight and cost.

 

Same size and volume of material: Micro-mix-filled resin (top) weighs a mere 44 gms. vs. 91 gms. of calcium carbonate-filled resin (bottom). Micro-mix also makes the finished product easier to grind, clean, and drill.
