ENTHONE B3

Main features

  • Four-Hour Ink Pot Life
  • Controlled Heat-Cure Processing
  • Faster Cure at Higher Temperature

Product Description

ENTHONE B-3 Catalyst is a heat-cure-only catalyst component for ENTHONE M-Series epoxy marking inks. It provides an average 4-hour pot life after the specified induction period, giving a defined processing window before the ink begins to solidify. Cure temperature must exceed 79 deg C, and higher temperatures shorten the required cure time within the published ink-film schedule. B-3 is used where permanent epoxy markings are processed through controlled thermal cure, including supported M-Series color packages and premeasured bi-pack configurations.

Key features

  • Heat-Cure-Only Processing: B-3 is used exclusively with controlled thermal cure.
  • Four-Hour Pot Life: The catalyzed ink has an average 4-hour working pot life after induction.
  • Temperature-Responsive Cure: Higher cure temperatures reduce the required ink-film cure time.

Applications / Suitable for

  • ENTHONE M-Series heat-cured marking inks
  • M 0 N and M 9 N bi-pack configurations
  • M 0 NC nonconductive black bi-pack configurations

Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.
