Well-known for its proven hiding benefits, new innovations in EVOQUETM Pre-Composite Polymer Technology are offering improved paint film properties to formulators, including exceptional chalk resistance, gloss and color retention and efflorescence resistance.
Dow Coating Materials (DCM) will present these and other solutions for the paint industry at the European Coatings Show in Nurnberg, Germany, March 19-21, 2013. Among the technologies showcased will be a new family of pure acrylic binders that help to optimally space TiO2 and extenders in the creation of a homogenous paint film with exceptional exterior durability.
“The need for longer-lasting paints that can reduce the frequency of repainting exteriors is an industry-wide concern we can help customers address with EVOQUE Technology,” said Marie Bleuzen, European Technical Manager, Architectural Coatings. “Our natural exposure data has confirmed the benefits that customers can see in their final paint film, from stain resistance and tannin blocking to a lower tendency for chalking.”
Dow will share these findings at ECS in a presentation on the new range of acrylic binders for optimal paint film structure with improved exterior durability. The business will also explain how EVOQUE Technology can facilitate high-quality interior paints, based on either pure acrylic or styrene-acrylic chemistries, with improved resistance to household stains.
“Our customers are familiar with how EVOQUETM Technology can enhance film opacity and make TiO2 work more efficiently,” said Andrew Trapani, Technical Director, Europe, Middle East and Africa, Dow Coating Materials. “They may not be as familiar with how the better spacing of pigment made possible by EVOQUE Technology can result in better film performance. This technology is a real breakthrough and we’re excited to show more of the benefits it can bring like improved durability and reduced film permeability.”
The Dow Coating Materials team will also be on hand to discuss the sustainability benefits of EVOQUE Technology as outlined in a recent Life Cycle Assessment of water-borne paints for interior and exterior wall protection. Conducted by the business and validated by a third party, the LCA found that because pigment often contributes the most to the environmental impact of paint, reductions in pigment usually lead to the biggest gains in sustainability.
Compared to other binder technologies, EVOQUE Pre-Composite Technology was shown to yield the lowest impact for all impact categories in the study, including human toxicity, primary energy usage and resource depletion. These results were shown to be driven mainly by the reduction in TiO2 facilitated by EVOQUE Technology, with the improved durability of the resulting composite-based paint playing a role in lowering overall impact, as well.
“Raw materials account for the lion’s share of the environmental impact in paint and using TiO2 more efficiently can help formulators significantly reduce that impact,” said Houshang Kheradmand, European Technology Awareness and Innovation Manager, LCT/LCA – SD Expert, Dow Coating Materials. “We like to say that sustainability is a journey, and the improvements offered by EVOQUE Technology can help push the industry toward better sustainability profiles for paints and coatings while delivering premium performance to other properties such as stain and scrub resistance.”
