PREFACE

A few years ago the producer and consumer of paints possessedcomparatively little knowledge of the relative durabilityof various pigments and oils. There existed in some cases aprejudice for a few standard products, that often held the userin bondage, discouraging investigation and exciting suspicionwhenever discoveries were made, that brought forth new materials.Such conditions indicated to the more progressive, theneed of positive information regarding the value of variouspainting materials, and the advisability of having the questionsat issue determined in a practical manner.

The desire that such work should be instituted, resulted inthe creation of a Scientific Section, the scope of which was tomake investigations to determine the relative merits of differenttypes of paint, and to enlighten the industry on various technicalproblems. Paint exposure tests of an extensive nature werestarted in various sections of the country where climatic conditionsvary. This field work was supplemented in the laboratoryby a series of important researches into the properties of pigments,oils, and other raw products entering into the manufactureof protective coatings. The results of the work werepublished in bulletin form and given wide distribution. Thedemand for these bulletins early exhausted the original impress,and a general summary therefore forms a part of this volume.

The purpose of the book is primarily to serve as a referencework for grinders, painters, engineers, and students; matter ofan important nature to each being presented. Without repetitionof the matter found in other books, two chapters on rawproducts have been included, and they present in condensedform a summary of information that will prove of aid to onewho desires to become conversant with painting materials witha view to continuing tests such as are outlined herein. Inother chapters there has been compiled considerable matter fromlectures and technical articles presented by the writer beforevarious colleges, engineering societies, and painters’ associations.

[viii]The writer wishes to gratefully acknowledge the untiringefforts of the members of the Educational Bureau of the PaintManufacturers’ Association, whose early endeavors made possiblemany of the tests described in this volume. Kind acknowledgmentis also made to members of the International Associationof Master House Painters and Decorators of the United Statesand Canada, who stood always ready to aid in investigationswhich promised to bring new light into their art and craft.
