Leveraging our more than 50 years of coating technology expertise, we collaborated with industry experts to develop an effective chemical technology solution for silica dust control. SandTec® is a proven silica dust control proppant coating technology, which, when applied to frac sand, results in significant reductions in respirable silica dust to below OSHA’s new PEL. Unlike mechanical and PPE systems, SandTec® minimizes silica dust generation from the mine to the wellhead, spanning the entire hydraulic fracturing supply chain.
With SandTec®, silica dust reduction is built into the sand–frac sand treated with SandTec® delivers up to a 99% reduction in silica dust throughout the supply chain. It is a cost-effective solution to silica dust control and is easy to apply with no drying or curing required. Unlike mechanical dust control systems, SandTec® does not occupy valuable real estate on the frac site and eliminates trip hazards associated with mechanical systems, further improving worker safety and site conditions. It is environmentally friendly – SandTec® is 100% biorenewable and biodegradable. Most importantly, SandTec® is miscible and compatible with frac fluids – it does not slow fracturing operations or negatively affect well performance.

Our engineers and technical experts work closely with E&Ps, service providers, and sand companies to deliver a complete SandTec® solution that includes both the coating and an application system customized to their unique needs. With SandTec®, you will benefit from high-quality, low-dust frac sand for your hydraulic fracturing operations.
