GENERAL DESCRIPTION: RSC-301XB is a light blue room temperature curing, epoxy surface coat. RSC-301XB will serve a variety of applications as it is a universal surface coat. RSC-301XB has excellent brushability and will not sag on vertical surfaces. The unique aspect of this surface coat is it's ability to bond to another surface coat or laminating resin after it is fully cured. Most surface coats must have the second surface coat applied within 45-60 minutes. RSC-301XB with SC-150-NB hardener can be applied up to 24 hours after the initial surface coat. By letting the first surface coat tack or cure fully you eliminate air holes on the surface and telescoping of fiberglass fabric. This process has many advantages over most others.
