kRT 100™ Proppants


kRT 100

Hexion’s kRT 100™ proppant is an economical, curable resin coated sand available in 100 mesh. The resin coating supports the intended use of 100 mesh within the fracture network, but now provides all the traditional benefits of a resin coated sand such as proppant flowback control and fewer proppant fines.

Typical Applications

Fracture treatments:     

  • At closure stress up to 12,000 psi [83 MPa]  
  • At bottom-hole static temperatures from 110 - 450°F [43 - 232°C]
  • Where smaller mesh size curable resin coated proppants are desired

Technical Advantages and Benefits

  • Enhanced conductivity
  • Proppant flowback control
  • Proppant fines reduction
  • Cyclic stress resistance
  • Minimizes proppant embedment
  • Reduces respirable silica dust exposure below PEL limits
