Technical Data Sheet

Black Pro


Black Pro™

Resin Coated Sand with Stress Bond™ Technology


Black Pro proppants are an advanced curable resin coated fracturing sand available in a 40/70 mesh size.  Black Pro resin is applied to a high quality frac sand. Incorporating Hexion’s Stress Bond technology, the proppant bonds in the fracture with closure stress, providing increased fracture flow capacity and proppant flowback control.



Fracture treatments:

  • At closure stress up to 12,000 psi [83 MPa]
  • Where higher fracture flow capacity and proppant flowback control are desired


  •  Reduces proppant fines generation and migration 
  •  Helps prevent proppant flowback 
  •  Stress Bond technology helps prevent wellbore consolidation 
  •  Frac fluid and breaker friendly 


  •  Grain-to-grain contact must occur and closure stress must be applied during the cure period for proper bonding
