PREFACE


A few years ago the producer and consumer of paints possessed
comparatively little knowledge of the relative durability of various
pigments and oils. There existed in some cases a prejudice for a few
standard products, that often held the user in bondage, discouraging
investigation and exciting suspicion whenever discoveries were made,
that brought forth new materials. Such conditions indicated to the more
progressive, the need of positive information regarding the value of
various painting materials, and the advisability of having the questions
at issue determined in a practical manner.

The desire that such work should be instituted, resulted in the creation
of a Scientific Section, the scope of which was to make investigations
to determine the relative merits of different types of paint, and to
enlighten the industry on various technical problems. Paint exposure
tests of an extensive nature were started in various sections of the
country where climatic conditions vary. This field work was supplemented
in the laboratory by a series of important researches into the
properties of pigments, oils, and other raw products entering into the
manufacture of protective coatings. The results of the work were
published in bulletin form and given wide distribution. The demand 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 reference work for
grinders, painters, engineers, and students; matter of an important
nature to each being presented. Without repetition of the matter found
in other books, two chapters on raw products have been included, and
they present in condensed form a summary of information that will prove
of aid to one who desires to become conversant with painting materials
with a view to continuing tests such as are outlined herein. In other
chapters there has been compiled considerable matter from lectures and
technical articles presented by the writer before various colleges,
engineering societies, and painters' associations.

The writer wishes to gratefully acknowledge the untiring efforts of the
members of the Educational Bureau of the Paint Manufacturers'
Association, whose early endeavors made possible many of the tests
described in this volume. Kind acknowledgment is also made to members of
the International Association of Master House Painters and Decorators of
the United States and Canada, who stood always ready to aid in
investigations which promised to bring new light into their art and
craft.
