Speaker's Tour 1/2 Day Seminar

All incorporated sections (GGSCT, PNWSCT PDX & VanBC) will host a lunch to evening 1/2 day seminar including 4 technical guests:

1. Beth Howard – FP Pigments: Mechanism and Use of an Opacifying Pigment
• FP-Pigments is a unique, opacity pigment manufactured in an interesting manner. The pigment was designed 11 years ago in Finland.  The pigment is an encapsulated TiO2. These one micron particles space the TiO2 particles contained within them perfectly. The TiO2 is surrounded by ultra-pure precipitated calcium carbonate. This presentation will explain some of the mechanisms of the hiding properties and also review a real life example of the use of this newer pigment.

2. Stuart Lipskin – BYK: The Pursuit for the Perfect Coatings Finish
• To obtain the ‘perfect coatings finish’ one must eliminate the appearance issues.  The problems can be the result of color, surface tension, foam and/or rheology.  With the use of pictures and videos, this presentation will review reasons for coatings defects and provide an understanding of the potential solutions. Areas to be discussed:
i. Reasons and importance of coatings
ii. What coatings defects occur and their effect on the coating performance
iii. How to test / measure quality of a coating
iv. An understanding of the reason for the defects
v. How to reduce / eliminate the defects through a basic understanding of the concepts of additive functionality

3. Rob Casteneda – Lanxess: The Fundamentals of Choosing an In-Can Biocide for Paints and Coatings
• Most of the paints and coating systems for architectural applications are water based. Even more some of the solvent based systems are changing to water based following both environmental challenges and technology development. Cost is also a very important driver in this trend of making more efficient and ecological paints and coating systems. However, this change carries an additional challenge: Microbial susceptibility. The microbial growth leads to the degradation of the paint. Some typical characteristics of a spoiled paint are: loss of viscosity, discoloration, odor and change in physical properties. This shift to more water based formulations makes it critical to incorporate the appropriate biocide system into the formulation to control the microbial growth. 

Historically, isothiazolines, bronopol, and formaldehyde releasers have been the biocides of choice for preventing microbial growth in the container. Besides these commonly used active ingredients, Dibromodicyanobutane (DBDCB) has been used successfully in other industries and these excellent results could be easily transferred to paints and coatings. This presentation will address the fundamentals of choosing in can preservatives and also convey some of the issues formulators must encounter when choosing a biocide.

4. Chris Crawford – Hydrite: Evolution and Advances in Foam Control
• The continual evolution of Paints and Coatings to higher performance while meeting the regulatory needs of an ever-changing environment has driven many of the specialty chemicals required to newer heights. One area of the greatest evolution is that of Foam-Control.  Never in the history of the need for foam control has the technology hurdle been set so high.  The days of silica dispersed into some solvent to create a defoamer/antifoam are gone and replaced with technologies such as specialty esters, acetylenic diols, modified ureas, polyamides, hyper-branched polymers and specialty silicone polyethers (SPEs).  The need for evolution continues to increase to keep pace with the evolution in Paints and Coatings.   This evolution has pushed formulators to search for better suppliers with a deft command of technology to provide that foam control chemistry that will fill the gap.



Amanda Andrews – WACKER Chemie: WACKER’s Silicone Innovation Provides Various Solutions for Coatings
• Silicones create innovation solutions for countless types of coatings: exterior/interior wall applications, wood protection, roof coatings, elastomeric coatings, natural stones and more.  In 1963 WACKER patented a new technology; an aqueous dispersion of organopolysiloxane resin used in paints to provide excellent UV and water protection.  Development of polysiloxane and silane emulsions soon followed.  Novel silicone emulsions opened doors to new opportunities in water based products to provide essential roles in coatings over the past 50 years. Countless buildings, decks and walls have been coated using silicone technology; thus providing a clean, water protected and high quality appearance.  Years of true outdoor exposure, precise testing and effective solutions for coatings have resulted in silicones as an appealing technology.  Silicone emulsion technology provides long term hydrophobicity with visual water beading, increased film durability, flow and leveling, easy to clean applications, decreased dirt pick up, and UV stability.
