Recommended Procedure for Application
  • Clean, dry and abrade application surface. More the degree of surface preparation better the the performance of . If possible, it is recommended that the surface be grit-blasted to a Near White Metal SSPC-SP10 Standard. For less severe applications, roughening the surface with hand tools or grinding is suitable.
  • Solvent cleaning with Paradigm thinner is recommended as the final step of cleaning. Mix entire kit onto a clean and dry mixing surface and mix thoroughly until color is uniform.
Application
  • Apply fully mixed material to the prepared surface.
  • At 25 °C working time is 65 minutes and functional cure time is 24 hours.
Important Point to be Remember
  • Working time and cure depends on temperature and mass : Higher the temperature, faster the cure. Larger the mass of material mixed, faster the cure.
  • To speed the cure of epoxies at low temperatures : Store epoxy at room temperature. Pre- heat surface to be repaired until warm to the touch
  • To slow the cure of epoxies at high temperatures : Mix epoxy in small masses to prevent rapid curing. Cool resin/hardener component(s)
