Metrix Armor is an industry leading wet strength resins technology platform that can deliver cost-effective performance to meet the challenging demands of grades requiring the highest wet strength properties. Wet strength resins are a necessary and critical papermaking additive for many grades of tissue, towel, specialty, and paperboard. These paper grades have a full range of wet strength demand depending on the use of the paper. Operational variables -- the amount and type of recycle fiber, the amount and type of filler, refining, and other wet end additives, can have a big impact on the efficiency of wet strength resins.
