Title: Innovations of Raymond L. Bender in Wood Adhesives

Introduction

Raymond L. Bender is a notable inventor based in Bakerstown, PA (US). He has made significant contributions to the field of wood adhesives, particularly through his innovative patent related to phenol-resorcinol-formaldehyde resins. His work has implications for the manufacturing of fast-curing adhesives used in various applications.

Latest Patents

Bender holds a patent for "Phenol-HCHO-resorcinol resins for use in forming fast curing wood." This patent describes a phenol-resorcinol-formaldehyde resin and a method for its production. In this method, phenol and formaldehyde are reacted at an initial pH of 8.5 to 9.2 in the presence of a sodium sulfite catalyst. The reaction mixture is heated and refluxed until it reaches a viscosity of u-v on the Gardner bubble test. Additional resorcinol is incorporated, and refluxing continues until the viscosity is between 30 to 100 Gardner sections. The mixture is then diluted with a water-miscible solvent to achieve a resin solution with a solids content of about 40 to 60 percent by weight and a viscosity of 2.0 to 3.5 poise. An alkali metal carbonate material is added to enhance the curing speed of the adhesives, and fumed silica is introduced to make the solution thixotropic.

Career Highlights

Bender is associated with Koppers Company, Inc., where he has applied his expertise in adhesive technologies. His innovative approach to resin formulation has contributed to advancements in the industry, particularly in the development of fast-curing wood adhesives.
