TC-890 A/B incorporates a non-mercury based catalyst system that produces a tough 80 shore D material with a 5-minute work time. This system can be used to hand pour electronic housing, models of all kinds, and point of purchase items. This system is also available in a 20-minute work time (TC-892), and a 12-minute work time (TC-891).

Product Highlights:
  • Non-mercury
  • Convenient mixing ratio: 1 to 1 parts by weight
  • Low viscosity, flows easily
  • Demold time: 1-2 hours at ambient temperature in a silicone rubber mold (1/8" thick section)
