White Seal's Stability with 5 Coats of Moisture Block
White Seal™ was developed to offer diemakers and converters a stable diebase for dies matched to steel counters. White Seal™ is constructed of 5 coats of moisture inhibitive polymers applied over an aged, low-moisture content dieboard, designed to remain stable when matched to a steel counterplate. This new dieboard is a lower-cost stable alternative to heavy, expensive, composite dieboards.
