Cure Indicator Temperature-Sensitive Ink

Cure Indicator Temperature-Sensitive Ink

Cure Indicator Ink is a solvent-based ink that is designed to be gravity-fed through a Beugler striping wheel to apply to substrates such as an uncured rubber hose.

When the hose is wound onto spools to be steam-cured in an autoclave, for example, the red pigment in the ink changes to white to indicate that the marked rubber has reached the desired cure temperature.

This color change is activated when the temperature reaches 250-300 degrees Fahrenheit and is sustained for a period of time. The higher the temperature, the quicker the color changes, as this process is time-temperature dependent.

Cure indicator ink takes the guesswork out of knowing how much rubber has cured. It also reduces scrap and the risk of supplying hose or tube to the end-user that could fail.
