Practical Wood Coatings Formulation and Application Course Revised and Updated!

The Practical Wood Coatings Formulation and Application course is a 3-day intensive training combining both lecture instruction and laboratory demonstration. The course discusses historical aspects of wood coatings as well as the current state of the art. The course discusses solvent-based, water-based, and UV technology in a comparative and enlightening manner. The course is a comprehensive technical, marketing, and idea generation, resource. Students will leave the course with a heightened sense of confidence regarding their knowledge of wood coatings. This course is a must for formulators, chemists, applicators, users of wood coatings, as well as sales, marketing, and technical service personnel of raw material suppliers.

Explanation of Agenda

The Practical Wood Coatings Formulation and Application Course is designed to systematically teach and train the student by taking them through each phase of the wood finishing, formulation, and application process. As such, the course starts off with an overview of the segments of the wood coatings market, inclusive of some detail of market size, technology type utilized, and potential areas for research.

We will then proceed in Day 1 to provide an overview of coating composition, followed by methodically taking the student through the finishing process—beginning with a detailed look at the wood substrate, followed by a thorough examination at the each aspect of the finishing process. By utilizing this procedure, students will gain insight into the how's and why’s of finishing, as well as achieving an understanding of the types of coating formulations utilized, inclusive of an in-depth look at matting. We will also review pigmentation in wood coatings, and discuss specialty finishes, particularly deck and floor coatings.

The dry lab provides students the opportunity to view and discuss issues faced by coating chemists.

The laboratory portion will consist of various demonstrations; of particular importance will be the formulation of various components of a cherry wood finish, followed by finishing a cherry piece. This allows the student to put into practice the lecture material discussed, and personally experience how various raw materials and coatings impact the finish. Students will gain an appreciation for the complexity of the finishing process, while also gaining insight into necessary requirements for successful introduction of new technology and materials.

Day 2 of the training will focus on technology and application of solvent-based and water-based coatings. The training will systematically compare the technology of solvent-based coatings with that of water-based coatings. Students will gain insight to the utility of different types of polymers. Comparisons of water-based technology with solvent-based technology in terms of rheology, viscosity, flow and leveling, appearance, and application will allow the student to discern the critical differences between the technologies and factors necessary for successful formulation and/or introduction of new technology into the marketplace.

The reactive polymers session will discuss the chemistry, crosslinking, and formulation of aminoplast based coatings, polyurethanes, and ultraviolet cured coatings.

The demonstrations comparing water-based technology to solvent-based technology will allow the student to experience actual challenges faced by coatings chemist in attempting to replace solvent-based technology with water-based technology. The 100% solids coating demonstration allows the student the opportunity to work with these materials, while obtaining experience with the flat line process, and floor coatings in particular.

Students will have opportunity to calculate, analyze, and compound a formula; the student will have opportunity to perform QC checks on the formulation as well.

This course will present the student with knowledge of the wood coatings marketplace and foster creative ideas for development and marketing of coatings, polymers, minerals, colorants, and additives.
