Abrafati 2019, deemed Latin America’s largest coatings trade show in Latin America. The 2019 conference will be held in Sao Paulo, Brazil from October 1-3, 2019.
Momentive offers an extensive portfolio of high-performance additives, emulsions and prepolymers. Our silanes team of experts spend everyday in the lab, carefully collaborating with you to offer numerous applications that meet the ever-evolving needs of the coating additive industry.
CoatOSil DRI waterborne silane is a silicone resin which serves the roof coatings, exterior coatings, wood coatings and industrial coatings. Lastly, our SPUR+ prepolymer portfolio offers.
Lastly, our SPUR+ prepolymer portfolio offers of a variety of grades designed to help optimize a variety of formulations. Explore the diverse lineup from the SPUR+ family to discover the product best suited to your application.
This year, at Abrafati, we will showcase the benefits of CoatOSil MP 200 silane and CoatOSil T Cure silane oligomer. CoatOSil MP 200 silane, principally serves the architectural, paints, resins, acrylic sealants and waterproofing industries. CoatOSil T Cure silane oligomer is marketed primarily for use in industrial and automotive paints.
CoatOSil MP 200 silane has inherent qualities for both solvent- borne and waterborne properties. It promotes adhesion through its ability to react to various organic functionalities, and bond well to inorganic substrates.
CoatOSil* T-Cure silane is a 100% active mercapto silane useful as a crosslinker and adhesion promoter for coating, adhesive and sealant applications. Its area of primary utility is in polyurethane based systems, but it may also find use in epoxy, acrylate and hybrid coatings.
CoatOSil DRI waterborne silicone is a low viscosity emulsion that can act either as a co-binder or additive in latex systems.
The innovative technology behind CoatOSil DRI silicone resin makes it an excellent candidate to consider for use in roof coatings, exterior coatings, wood coatings and industrial coatings
In the coatings market, silicone emulsions are known for their durability, water repellency, low VOC, and resistance to other environmental elements. Momentive’s silicone emulsions can help create longer-lasting, protective coatings that maintain aesthetics in interior and exterior architectural applications.
SPUR+* 1050 prepolymer is an excellent candidate to consider for use in the manufacturing of one-part, moisture-curing sealants and, as a base resin, for medium modulus sealants and adhesives, typically providing the higher tensile strength often required in industrial and transportation applications. With low viscosity and easy application, SPUR + 1050 prepolymer generally adheres well to many surfaces without the aid of a primer.
SPUR+ 3030 prepolymer was developed to enable the formulation of roof coating with a wide application window and excellent fully cured properties including tear, UV and water resistance.

ABSTRACT: Controlling the dispersion of precipitated silica into a rubber compound matrix is a significant challenge for achieving the consistent mechanical property improvements that are characteristic of polymer nanocomposites, as inorganic silica aggregates are generally immiscible with the organic elastomeric phase. To prevent silica flocculation, the silica surface is hydrophobized by grafting amphiphilic silane molecules such as 3-Octanoylthio-1-propyltriethoxy silane (OPTES), a blocked mercapto silane trademarked NXT* silane by Momentive Performance Materials Inc.
This approach has been successful for silica dispersion. However, the silica aggregates exhibit self-assembly into highly anisotropic structures depending on the amount of grafted silane per square nanometer of silica surface area, which directly affects the mechanical properties of the rubber. Simulations suggest that this self-assembly reflects a balance between the energy gained when the polar silica aggregates re-flocculate and the entropy of distorting the grafted silane molecules. Both simulation and experimentation demonstrate that considerable control of filler morphology within the polymer matrix is possible through targeted silanization, resulting in enhanced mechanical properties of silica-filled rubber.
