TAPPI T 845 om-14
Wet pin adhesion of corrugated board by selective separation
standard by Technical Association of the Pulp and Paper Industry, 2014
Full Description
This method measures the force required to separate the linerboard facings from the medium in corrugated board after the board has been immersed in water for a period of time. It may be used to evaluate the water resistance properties or levels in water resistant adhesive.
This procedure mirrors the process in T 821 "Pin Adhesion of corrugated board by selective separation" with differences in how samples are prepared for testing and how results are interpreted.
