Protection with specialty methacrylates
Coatings
Methacrylate monomers manufactured by Evonik are the ideal choice for coatings that demand exceptional film-formation, adhesion, durability, and gloss properties. The extensive range of VISIOMER® methacrylate monomers allows formulators in the coatings industry to accurately tailor the resin properties to meet specific performance requirements such as chemical resistance, adhesion, metal protection, or preservation of natural wood.
Architectural coatings, also known as building coatings, are used to protect and enhance the appearance of wooden or concrete structures. These coatings are formulated with methacrylate resins, which provide excellent film-formation, adhesion, durability, and gloss properties. VISIOMER® methacrylate monomers offer a broad portfolio of options for resin producers to design coatings with specific properties. For example, VISIOMER® MPEG 750 MA W and VISIOMER® MPEG 1005 MA W provide waterborne paints with low temperature stability, while VISIOMER® MEEU 25 M and VISIOMER® MEEU 50 W improve paint adhesion and wet scrub resistance of wood coatings.
OEM and refinish automotive coatings play a crucial role in ensuring that vehicles are not only visually appealing but also protected from environmental factors such as UV rays, scratches, and other forms of wear and tear. These coatings are typically made up of a combination of methacrylate resins and diisocyanates, which work together to create a flexible and durable finish. However, to achieve a high-gloss finish and improve leveling, high-solids monomers like VISIOMER® Terra IBOMA and VISIOMER® c-HMA are often added.
High bio-content VISIOMER® Terra IBOMA is used to obtain high-solids coatings with low VOC while ensuring better durability and long-lasting high gloss finish.
Overall, the use of high-quality coatings in the automotive industry is essential for maintaining the appearance and protecting the surface of vehicles. By incorporating monomers like VISIOMER® Terra IBOMA into their formulations, manufacturers can create coatings that not only perform well but also have a positive handprint due to the reduction of VOCs.
Industrial coatings are essential in various industries, including heavy-duty, can and coil, wood, construction, and flooring. These coatings typically comprise solvent-based or waterborne systems. By integrating VISIOMER® methacrylate monomers into the formulation, manufacturers can precisely adjust the resin properties, such as adhesion, metal protection, or natural wood preservation. This level of accuracy enables manufacturers to create coatings that meet the specific needs of their customers and applications, ensuring that the coatings perform optimally.
Protective coatings are essential for preserving equipment and infrastructure in harsh environments. These coatings, such as marine and infrastructure coatings, are designed to withstand extreme weather conditions, exposure to saltwater, and other corrosive elements. VISIOMER® methacrylate monomers are key components of modern coating systems, providing superior adhesion to polar surfaces like minerals, glass, and metals. For instance, VISIOMER® HEMA-P 70M and VISIOMER® HEMA-P 100 are popular options that enhance adhesion to these surfaces. In direct-to-metal coatings, these monomers also improve corrosion resistance, making them ideal for use in harsh environments. With their unique properties, VISIOMER® methacrylate monomers play a vital role in the development of advanced protective coatings that meet the demands of diverse industrial applications.
Printing ink resins are highly sophisticated formulations that require a precise combination of properties to achieve optimal ink performance. These properties include pigment wetting, adhesion to various substrates, viscosity control, surface tension properties, and more. Achieving the right balance of properties is essential for producing high-quality prints that meet the requirements of diverse printing applications. VISIOMER® methacrylate monomers are instrumental in this process by allowing ink formulators to create resins with the exact properties they need. This ensures that the ink performs exceptionally well in a range of printing applications, including packaging, labels, and publications.
VISIOMER® specialty methacrylates are used to synthesize polymerizable surfactants and enable thickening solutions for a wide range of applications. They allow flexible thickening solutions for a wide range of applications.
Dispersants
A dispersant is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve particle separation and prevent settling or clumping. Dispersants normally consist of one or more emulsifiers. Polymer dispersants are widely used in many products, for example in adhesives, detergents, photographic solutions as well as in agriculture, cosmetics and pharmaceuticals. You will also find them in cleaning and polishing products.
Emulsifiers
VISIOMER® MPEG methacrylates are often used as nonionic reactive emulsifiers. When used in emulsion polymerization, a large fraction of the emulsifier molecules become irreversibly bound to the emulsion polymer chains and droplets. This can both improve latex stability and reduce foaming.
Thickeners
Acrylic thickeners are commonly produced by emulsion polymerization. One of the most important monomers are the so called associative thickeners. Associative thickeners are based on hydrophobically modified polymers that combine high thickening efficiency with a less marked shear-thinning viscosity profile. Here, viscosity/shear can be controlled by varying the length of the polymer’s hydrophobic groups and molecular weight.
