Abstract: This one hour presentation on surfactants initially reviews the various types and chemical structures of commercially available surfactants. The presentation progresses to a better understanding of various surface activities including surface area, surface tension, surface pressure, wetting, surface transport and micelle formation. Then, we explore the world of foam with respect to how surface active agents stabilize and de-stabilize foam bubbles at the surface or as entrained air. Finally, a review of measuring surface tension under both static and dynamic conditions.

Abstract: Low VOC is still a driver for coatings applications with the ultimate goal to be near zero VOC. Water reducible alkyds have been used for years for lower VOC applications, but are limited in how low of VOC can be formulated plus poor shelf stability due to hydrolysis. Alkyd emulsions can bridge the VOC and stability gap.
Alkyd emulsions are versatile for a range of end use applications. Long oil alkyd emulsion are used for wood stains. Medium oil alkyd emulsions are used for high gloss trim enamels. Chain stopped alkyd emulsions are used for industrial metal primers, non-highway pavement markings and DTM. Modified alkyd emulsions find a variety of end uses from black top sealers to concrete and stone sealers. Alkyd emulsions show improved performance over traditional waterborne petroleum based acrylic resins. This paper will explore the versatility of alkyd emulsions to solve your low VOC coating needs.

Abstract: This presentation on Rheology reviews the basic principles of rheology including its definition and its influencers – chemical structure, morphology, and environmental conditions. The impact by various deformation forces including compression, tension and shear will be examined to demonstrate flow and viscosity profiles as a function of stress, temperature and time. An examination of the chemistry of commercial rheological agents will help clarify their efficacy in various formulation types including waterborne and solventborne systems.
A full day course on Rheology is available via the following link . . . Rheology.

Water-based coating formulations are an industry trend due to stringent environmental regulations.
The majority of silicone coatings are solvent-based or high-solids, which require solvents for cleanup, and increase
overall project VOC emissions.
Silicone Water-Based Elastomers (SWBEs) are silicone elastomers offered as a water-based latex which provides
easy handling and formulation, with the resulting performance of a solvent-based or high-solids silicone coating.
SWBEs are ultra-low in VOCs and do not require solvents for cleanup. They offer good adhesion to variety of
substrates such as masonry, glass, metal, wood, and textiles; and display increased weatherability and water
resistance in ambient-cure or bake coatings for applications such as waterproofing, protective, anti-graffiti,
elastomeric, air and weather barriers, and paints.

There is a growing interest to move towards waterborne systems in the coatings industry. However, the change is not always straightforward and often new technologies are required to obtain the same performance as with solvent borne systems. Typical challenges related with the waterborne coatings is mud-cracking and open time. Waterborne coatings tend to dry significantly faster than their solvent borne counterparts and suffer from skinning, often leading to mud-cracking.
Microfibrillated cellulose (MFC) is a new, a value-added and multifunctional product made of cellulose, consists of fibrils with lateral dimensions in the nanoscale and lengths up to micron scale. Its unique combination of characteristics from water soluble polymers and insoluble fibers gives a versatile and efficient alternative to technologies currently available. MFC secures high viscosity at rest, giving good stability, as well as offering shear thinning behavior and rapid viscosity build-up, which prevents sag during application. The high inertness, compatibility and chemical stability of MFC opens up new possibilities for waterborne paints and coatings, especially for the more demanding formulations.
The will demonstrate how MFC can solve your challenges regarding open time and mud cracking combined with excellent spray properties.
