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. Evonik 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.

Defoamer for coatings

Searching for the optimal defoamer

Defoamer performance can be affected by a number of complicated formulation and application parameters, which makes selecting the optimal defoamer difficult and time consuming. Selecting the wrong defoamer can lead to defects, problems, and even to coating failure.

Evonik offers a complete portfolio of defoamers and deaerators, from organic oil-based to siloxane-based to our unique molecular defoamers.

wetting and dispersing additives

Efficient Wetting and Dispersing Additives

Cost reduction and process efficiency are major tasks for modern formulators. Improve the efficiency of your grinding process with grind aids, surfactants, and dispersants from Coating Additives.

Hydrophobing agents for exterior walls

Hydrophobing Agents

Treating surfaces–such as exterior walls–with water-repellent materials (or materials otherwise impenetrable to water) is an effective method of protection from weathering. To achieve outstanding hydrophobization, different types of silicone chemistries are used.

Defoamers and deaerators for waterborne coatings 

When dealing with coatings we know there might be no moment without the risk to create foam. All this foam lead in a lot of problems like the loss of weather resistance or corrosion protection. To get rid of that macro and micro foam we need defoamers and dearators.

As problems related to pigment dispersions become more frequent and as requirements regarding color reproducibility become increasingly rigorous, new demands for pigment wetting agents and dispersants are required to resolve these pigment stabilization issues. Over the past 20 years, advances in polymeric dispersants have made significant improvements in the process of wetting and stabilizing pigments. As a result, many dispersant technologies that better stabilize small pigment particles and that better prevent flocculation are emerging in the marketplace. This paper will explain pigment and dispersant interfaces and how harmonizing and optimizing these interactions will lead to a better pigment dispersion.
