Additives For Architectural Coatings

ADDITIVES FOR ARCHITECTURAL COATINGS

With regulations aimed at decreasing VOCs and the development of new waterborne polymer systems and other technologies to meet these regulations, obtaining the combination of desired properties for specific applications and formulations has become even more challenging and complex. AEOR Coating Additives can help obtain these properties.

In today’s environmentally conscious marketplace, formulators are challenged to be sensitive to the potentially negative environmental impacts of their systems. As global trends and regulations move away from many traditional materials, formulators are looking to transition to more environmentally friendly systems. Formulators are also challenged with reducing or even eliminating VOCs from their architectural systems.

OUR PRODUCT RECOMMENDATIONS FOR ARCHITECTURAL COATINGS COVER DIFFERENT TECHNOLOGIES 

Waterborne architectural coatings, PVC 0-30%

Low PVC: High-gloss paints with low water vapor permeability. Increased wet scrub resistance due to a high binder content. Mainly used for trim paints in the architectural coatings market.

Waterborne architectural coatings, PVC 30-60% 

Mid PVC: Semi-gloss to matte paints combine the advantages of low and high PVC paints. Average amounts of binder lead to a sub-critical PVC, which is characterized by a medium water vapor permeability and moderate wet scrub resistance.

Waterborne architectural coatings, PVC >60 % 

High PVC: Matte paints with an overcritical PVC have a rough and open pored structure, which leads to high water vapor permeability and without modification to high water absorption. High amounts of fillers and pigments leads to excellent dry hiding power compared to glossy coatings.

Solventborne paints

Paints should be able to perform well on a variety of different substrates. Although market share of solventborne coatings decreased over several decades, there are certain regional markets and applications (e.g. trim paints) for solventborne paints.

The range of decorative coatings covers interior wall paints, decorative wood and metal coatings as well as external coatings for facades and road marking paints.

In addition, pigment concentrates for tinting systems (both point-of-sales and in-plant tinting) are an essential part of the range of applications and related binder systems.

From clear coats to highly filled paints, AEOR offers special additives that comply with legal requirements for both aqueous and solvent-borne systems. There is an extensive additive portfolio for decorative and architectural coatings.

Wetting and dispersing agents are just as important as defoamers, rheological and surface additives.
