Extended Handling May Be Required
  • Porous construction allows varnishes to penetrate thoroughly
  • Compatible with “Scotchcast” Brand resins
  • 100% Rayon fiber backing
  • Another advantage of 1157R tape is its ability, because of its porosity, to pick up resin and become thicker, making a hard moisture and mechanical barrier on the outside of the coil
Overview
3M Electrical Tape 1157R is a porous rayon mat tape with acrylic pressure sensitive adhesive that is specifically designed to allow thorough penetration of the impregnating resin inside bobbin wound coils.
