The wood finish serves as an envelope for the wood substrate; its twofold purpose is to beautify and protect the wooden
substrate. The wood finishing process is made up of four interdependent parts: 1. Products, 2. Execution, 3.Environmental
Regulations, 4.Quality Control of the Wood Finish.
Wood finishing suppliers formulate, manufacture, and service wood finishing products for manufacturers of wood
furniture, kitchen cabinets, office furniture, and multi-purpose cabinets.
They also educate the manufacturer on how to apply and control the wood finish. In order to minimize problems in wood
finishing operations, the manufacturer and the finishing supplier must work closely together to be sure that each has a full
understanding of all of the factors that impact the quality, durability, cost, and environmental impact of the finished wood
[This presentation will assist] in the process of understanding the numerous variables involved in ‘building an industrial
wood finish.”

The challenge for the modern surface coating industry is to provide coatings with environmental compliancy and
sustainable design, most notable being low or zero VOC. This must be achieved simultaneously with high coating
performances, matching or preferably exceeding current performance. Towards this goal, we have developed a waterborne
paint system exhibiting thixotropic rheology along with excellent wet and dry paint properties. This paper describes the
salient design factors, including the synthetic and colloidal features, of this emulsion polymerized acrylic latex with
significantly improved rheological and dry coating properties. Comparison is made to solventborne and existing waterborne
thixotropic paints. Key properties are reviewed including gel strength and recovery for the wet system, and the enhanced
chemical and mechanical properties of the dry coating.

Waterborne wood finishes based on acrylics and other polymer technologies have been increasingly utilized as regulatory
pressures push coatings manufacturers and end-users towards coatings with an improved environmental profile. This
presentation describes the development of a new self-crosslinking acrylic resin for use in applications such as kitchen
cabinets and general wood finishes. A novel ambient crosslinking mechanism leads to faster property development and a
non-yellowing finish compared with current self-crosslinking acrylics. This new acrylic resin, when blended with a unique
polyurethane dispersion, imparts extremely fast coalescent release and rapid hardness development of the coating. Both the
acrylic and acrylic/polyurethane polymers facilitate the formulation of coatings with excellent appearance, hardness, and
chemical resistance properties. An evaluation of these resins in clear sealers and topcoats will be described. Their
performance will be compared to commercial waterborne and solventborne wood finishes.

                         An Important Process in the Application of Everyday Latex Paints

Water-borne latex paints are used in everyday life as decorative and as protective coatings. The application of these paints
is often taken for granted, but the drying process of latex paints involves the evaporation of water, solvents, and the
coalescence of latex particles to a polymeric film that contains pigments, dispersants and surfactants. A model has been
developed to better under the drying and coalescence of latex films. The temporary plasticization of latex particles by
filming aids and co-solvents is well known. A lowering of the glass-transition (Tg) below the cure temperature is necessary
for the interdiffusion of polymer chains between particles. The Tg evolution with time of latex films plasticized with
filming aids is modeled using fundamental equations. Both the wet-stage and dry-stage are modeled. Fundamental
equations for the wet-film stage contain the evaporation rates, the distribution coefficients of solvents, and wet-stage
activity coefficients. The activity coefficients of the solvents during the wet-film evaporation are determined by measuring
the minimum filming temperature of the plasticized latex film. Solvent loss is also modeled during the subsequent dry-
stage. Activity coefficients of solvent loss from latex films can be determined either gravimetrically or by measuring the
Tg evolution of the film as a function of time. The influence of temperature, humidity, and air-speed on drying is also
The Tg evolution of latexes formulated with Butyl CARBITOL is studied in detail. During the dry-stage, the hardening of
the film initially follows an evaporation controlled model for solvent loss, but then switches to a diffusion model as Tg of
the film approaches ambient temperature. Although the Tg evolution of a latex film is complex, it will be shown that the
initial Tg suppression produced by a solvent or solvents plays an important role in selecting the optimum solvent or solvent
combination for corrosion resistance.

A variety of woods are used to make interior OEM wood products like furniture, cabinets, floors. Woods vary in hardness,
pore structure, moisture content, sanding treatment, natural resin content, etc. Wood is finished with a variety of coatings
like solvent borne, waterborne, UV, and hybrids. Depending on selection of wood and coating to be applied, differences in
outcome have been observed sometimes identified as a problem. Some of these interactions will be discussed in this talk.

Consumers and markets are demanding products that are sustainable, lower cost, and higher quality products. UV-cure
powder coatings can meet these requirements and provide safer wood coating compared to traditional liquid finishing
materials. UV cure powder coatings combine high performance material chemistry, powder application technology, and
low energy consuming and high-speed finishing technology of the UV cure technologies. Low process temperatures and
UV light initiated cure are ideal for finishing wood composites, reducing substrate thermal exposures and providing higher
quality products. This paper presents an overview of UV-cure powder chemistry and application technology and will focus
on how combining UV cured powder coating chemistry with design requirements produce products of exceptional value.

The impact of exposure site (WI, OH, FL, AZ) and southern pine wood properties (density, growth rate, pith side/bark side)
on paint performance was studied. Both manual and camera-based observations were made at 3 month intervals for 15
months. A single coat of paint was used to speed failure. We found significant differences in substrate checking as a result
of paint type, location, and board density. Mildew was prominent in Florida while warping and twisting was pronounced at
the Arizona exposure site. Exposure in Madison, WI and Medina, OH produced very similar results.

On-Site UV Curing is a new technology on the rise primarily used for floor coatings for concrete, wood, vinyl and tile. It
offers improved productivity and environmental benefits without compromising the coatings performance. An investigative
study has been conducted focusing on the curing behavior and performance of these systems. Factors influencing the extent
of the UV curing reaction have been studied using FTIR spectroscopy and a comparison done with chemical and physical
testing. The performance was based on testing according to the MFMA (Maple Flooring Manufactures Association)
specifications and various field trials. This study also included a comparison of 2 portable UV curing equipment. General
learnings and recommendations on this technology will be discussed.

The properties of acrylic latices can be significantly improved by the copolymerization of a hydrophobic monomer such as
the vinyl ester of neo-decanoic acid (VE 10). These modified acrylic latices can be designed to meet specific high
performing criteria coatings by varying the monomers composition or by using techniques such as cross-linking and
core/shell. Substrates such as wood can be strongly affected by climatic variations resulting in many physical changes.
High performance coatings are therefore required to cope with these high demands. VE 10 modified acrylic coatings have
extremely high hydrophobicity and lower surface energy resulting in outstanding water resistance and water repellency.
Recent work on VE 10 modified acrylic latices has led to the development of self cross-linkable core/shell latices that have
a good hardness flexibility balance together with excellent adhesion and durability. These emulsion polymers are
particularly suitable for the formulating of high performance wood coatings. Ongoing testing of exterior protective wood
stains also shows very promising weathering resistance results.

        Prevention of Defects in Waterborne Wood Coatings through the Proper Selection of Foam Control Additives

The inclusion of surface active agents in a typical waterborne wood coating formulation generally leads to the tendency to
foam during manufacture, mixing and application. If stabilized foam is not minimized in these coatings, the dry films may
suffer from surface defects, reducing both the protective and aesthetic qualities of the finished surface. Defoamers are often
added to mitigate foam; however, as typical defoamers function via an incompatibility mechanism they may also create
additional surface defects such as craters, pinholes and fisheyes. In contrast, the more compatible molecular defoamers
often lack the power to effect quick foam knockdown. Thus determining the best defoamer for a given formulation is a
matter of finding a balance between the defoaming power or strength of the defoamer and the compatibility and solubility
of the defoamer in the system. This presentation will illustrate some of the fundamental causes and effects of foam in
waterborne coatings and describe the different mechanisms for defoaming. In addition, the methodology of selecting a
defoamer along with specific examples where proper selection of the defoamer enables excellent defoaming and aesthetics
in waterborne wood coatings will be discussed.

The performance of coated and uncoated wood surfaces is directly affected by the interactions of the polymer constituents
and the elements. The absorption of UV radiation leading to free radical reactions is the primary force leading to the
breakdown of wood polymers when exposed outdoors. Understanding these reactions, and in the future controlling them,
will be key to preventing the weathering of wood surfaces. This presentation will present the basic mechanisms associated
with the weathering of wood as we understand them today and some approaches, both historical and current, that can be
used to prevent surface degradation.
