Title: Innovations of Mark R Zentner

Introduction

Mark R Zentner is a notable inventor based in Mount Prospect, IL (US). He has made significant contributions to the field of thermally curable materials, holding a total of 3 patents. His work focuses on improving the properties and production methods of wet-impregnated rovings.

Latest Patents

Zentner's latest patents include a method of making thermally curable wet-impregnated rovings. These rovings are characterized by fibers that are impregnated with a liquid polyepoxide containing a latent heat-activatable epoxy curing catalyst, such as dicyandiamide. The polyepoxide dispersion has a room temperature viscosity ranging from 2000 to 5000 centipoises and a tack of less than about 6 on a Thwing-Albert inkometer. The production process does not involve organic solvents, as the dry multifilament roving is passed through an elevated temperature bath of the polyepoxide dispersion. This temperature is carefully controlled to be insufficient to activate the curing catalyst, allowing for uniform impregnation. The wet rovings can be stored in a supply package, which may be cop wound, and they resist running in a void-free wet fiber composite.
