FORMULATING WITH NEXT GENERATION RHEOLOGY MODIFIERS & DEFOAMERS FOR LOW/ZERO VOC WATERBORNE ARCHITECTURAL COATINGS GUILD CPO 2016 NASHVILLE, TENNESSEE
NEXT GENERATION Additives Decrease of VOC limits due to regulations. Raw material suppliers producing lower VOC capable raw materials. Raw materials latexes have unique morphology and stabilization package. Difficult to thicken. Generate foam micro and macro Conventional NiSATs and defoamers observed to be relatively inefficient in the lower VOC systems compared to higher VOC formulations. Paint formulators have to compromise on paint and film properties to achieve VOC targets. 2
NEXT GENERATION Additives Market Needs Introduction of differentiated product to the market. Dependence on additives (Rheology Modifiers & Defoamers) to provide needed differentiation. Need to develop Next Generation additives Improved thickening efficiency, anti-foam and defoaming properties. Improved paint, film and application properties. Environmentally friendly additives leading to the formulation of Green paints. 3
Waterborne Rheology Modifiers Use Nonionic Synthetic Associative Thickeners (NiSAT) Used mostly in DIY and high-end paints for improved application properties flow & leveling, spatter resistance, etc. Alkali-Swellable Thickeners Anionic acrylic thickeners mostly used in High PVC interior paints Clay-based Thickeners Used in paint formulations to improve syneresis control, sag resistance and anti-settling properties Polyolefin wax based anti-settling additives 4

DAPRO Defoamer Overview
New DAPRO Defoamers
Elementis: The Leader in Defoamers Elementis Specialties develops and manufactures: Hydrophobic Silicas Defoamers & Antifoams Custom Formulations Our major markets for defoamers include: Paints Inks Adhesives Paper and processing Oil processing Food processing Concrete / Construction Metalworking fluids
Guidelines for Defoamer Selection Basic Principles Important to use a combination of grind and letdown defoamers that work synergistically. Elementis has found that when the optimum grind and letdown defoamers are formulated together, less total defoamer will be required Grind defoamers require shear to disperse into the system. The lower the dispersibility rating, the more shear is required and the more effective the defoamer Typically, grind defoamers are very hydrophobic and not very dispersible Letdown defoamers do not require shear to disperse into the system The higher the dispersibility rating, the easier the defoamer will get into the system Typically, letdown defoamers are less hydrophobic and more dispersible
