Dow and Dow Corning Launch New High-Performance Silicone Water Repellent, Present on Advances in FRC Protection at IIBCC 2016

Acrylic Emulsion Polymers and Silicone-based Hydrophobers Offer Multiple Options for Integral and Post-treatment Water Repellency

Exhibiting here at IIBCC 2016 in booth H104, Dow Construction Chemicals and Dow Corning High Performance Building Solutions introduced today new Dow Corning® IE 6686 Water Repellent, a next-generation, silicone-based microencapsulation/ emulsion for fiber-reinforced cement (FRC) admixtures that delivers excellent resistance to water uptake and efflorescence. The two Dow entities are also spotlighting pure acrylic emulsion polymers for FRC basecoats and topcoats that can be used together or as alternatives to silicone-based protection. Additionally, representatives from both organizations are delivering presentations on the latest developments in the advancement of acrylic and silicone-based solutions for protecting FRC siding, roofing and flooring.

Now that Dow Corning is wholly owned by Dow, the two construction-facing organizations have joined forces to give customers an expanded portfolio, extensive building science expertise, strong R&D capabilities and globally recognized brands. Their combined presence here marks the first time the two have ever exhibited together at an IIBCC show.

Representing both Dow and Dow Corning, Axel Giesecke, Dow Corning’s global segment leader for Construction Chemicals & Infrastructure, is giving a presentation titled "Options for Silicon Based Hydrophobization of FRC Boards," that will provide an overview on the two organizations’ combined product offerings and joint capabilities. Giesecke will speak on Tuesday, 8 Nov., from 4:00 to 5:45 pm. as part of IIBCC’s Suppliers Day event.

Jean Paul Lecomte, Dow Corning’s technical service leader for Construction Chemicals will then present a technical paper on Wednesday, 9 Nov. at the IIBCC Conference. Titled "Use of Silicone Resin Emulsion as Integral Water Repellent for Mortar and Fibre Reinforced Cement Boards (FRC),"Lecomte’s presentation will start at 4:15 p.m. It will cover the advantages of using advanced, silicone-based water repellents as admixtures, an approach that protects the entire FRC component and enables on-site cutting without impacting hydrophobicity.

"Demand for FRC siding, panels, roofing and flooring, is strong and growing, particularly in Asia," said Giesecke. "Simultaneously the call for improved technologies to protect FRC components against damaging moisture uptake is also on the rise. As an integrated, customer-centric market leader, Dow and Dow Corning are now able to address these demands with an extremely deep and broad portfolio of both internal and post-treatment water repellency options that make it easier to create highly durable, safe and attractive commercial and residential structures."

Silicone Hydrophober Technologies
Dow Corning is exhibiting a number of silicone-based hydrophober solutions that can minimize water absorption and efflorescence, provide longer-lasting aesthetics and enhance durability.

- New Dow Corning® IE 6686 Water Repellent, introduced here today, is an oil-in-water microencapsulation/emulsion of a silicone resin that contains 30 wt. percent of active material. Used as an admixture, it significantly reduces water uptake and efflorescence. The silicone resin is emulsified and microencapsulated in a silica-based shell, which protects it and facilitates mixing/dispersing in water. This new solution was developed specifically for retention in FRC boards that are formed using the Hatschek process.
- Dow Corning® Z 6289 Resin is an alkyl-functionalized, low-viscosity silicone resin used as an admixture.
- Dow Corning® 520 Dilutable Water Repellent is a silane/siloxane emulsion blend that is dilutable in water.
- Dow Corning® IE-6683 Water Repellent, a silane/siloxane emulsion blend, is dilutable in water to formulate a <200 g/l volatile organic compound (VOC) water repellent.
- Dow Corning® IE-6682 Emulsion is an impregnation sealer for masonry and cement surfaces.
- Dow Corning® IE-6694 Water Repellent is a 60 percent active, low-VOC, water-dilutable silicone emulsion for treatment of porous construction materials.

Acrylics for FRC Coatings
In combination with or as an alternative to silicone-based protection, Dow Construction Chemicals offers various pure acrylic emulsion polymers for clear and pigmented basecoats and topcoats. Pure acrylics, a proven technology for use as FRC coatings, deliver excellent durability and resistance to efflorescence and alkali. Among the high-performance materials being showcased at the Dow/Dow Corning booth are acrylic emulsion polymers that offer a range of glass transition temperatures.
