Resin contains no nitrogen, and the hardener is free of phosphorous and sulphur greatly reducing surface and subsurface
Defects
[ FEATURES ]
Phenolic No-bake resins are a brownish-red transparent liquid cured with an organic ester:
1, Resin contains no nitrogen, and the hardener is free of phosphorous And sulphur greatly reducing surface and subsurface defects.
2, The resins thermoplastic properties and secondary high temperature Hardening process reduce hot tear and veining defects in steel and Ductile iron castings.
3, Improved plant working environment as a result of no noxious or Irritating odors during sand mixing, core production, and pouring.
4, Excellent shakeout characteristics contribute to the overall efficiency of The process.
1, Proportioning:
Resin: 1.2 - 2.0% (based on sand)
Hardener: 20 - 25% (based on resin)
2, Mixing process:
Mix sand with hardener first, and then resin. Typical mixing time is 5 to 60 seconds.
3, Different types of hardeners or hardeners with different curing speed can be used to adjust curing speed(AP Resin hardener regulator can be applied), as in the graphs below, 20° C.
