Abstract

Proppants coated with a cured reactive resin composition containing 92-99.5 wt. % of a reactive resin and 0.5 to 8 wt. % of a silicone resin containing at least 5 wt. % of alkoxy groups and at least 20 mol percent of T and/or Q units, in liquid form, exhibit high freedom from fines generation, and are free flowing.
