Arosil Powder - A Grade

Fumed silica powder grade A for viscosity control, thixotropy, and anti-settling in resin and coating formulations.

About this product

Arosil-type fumed silica is a very fine silica additive used to build thixotropy, reduce sag, and improve suspension in resin, gelcoat, adhesive, and coating systems. The exact surface treatment and performance of grade A versus B should be confirmed from the supplier TDS.

Applications

Polyester resin; epoxy; gelcoat; adhesives; putties; sealants; coatings; composite compounds; anti-sag formulations

Key features

Fine silica filler; viscosity and thixotropy modification; improves suspension; helps reduce sag; compatible with many thermoset formulations

Recommended use

Disperse gradually under controlled mixing and optimize loading by rheology and application testing.

Not recommended for

Not a stand-alone resin or curing agent; not intended for uncontrolled addition without dispersion equipment or formulation trials.
