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.
NEXT GENERATION Additives

• 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.
NEXT GENERATION Additives – Market Needs
©2016 Elementis Specialties, Inc.
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
Waterborne Rheology Modifiers Use

• Two main chemistries
• Polyether – Urea – Polyurethane (PEUPU)
• Polyether Polyol (PEPO)
• Two main shear-effective NiSATs.
• Low/Mid Shear
• High Shear

DAPRO® Defoamer Overview

New DAPRO® Defoamers

Elementis: The Leader in Defoamers
Elementis Specialties develops and manufactures:
Hydrophobic SilicasDefoamers & AntifoamsCustom Formulations
Our major markets for defoamers include:
• Paints
• Inks
• Adhesives
• Paper and processing
• Oil processing
• Food processing
• Concrete / Construction
• Metalworking fluids
©2016 Elementis Specialties, Inc.
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
