Silicon-Based Technology for the Coatings Industry – An Overview Type ZY Premium Type ZY Type ZS Type Z Type GZ FIGURE 5 | Structures can be a combination of these, where R can be methyl and/or phenyl. SiLibeads ® in a wide range of coatings formulations. They are primarily used to impart UV and thermal resistance in applications such as exhaust stacks, cookware and lighting fixtures. Silicone resins can be developed with a wide range of flexibility, from soft to hard and brittle – and a range of organic compatibility FIGURE 6 | Siliconates. (Figure 5). New research continues to investigate new resin technologies designed to meet specific needs identified by customers. These include organo-modified resins, which incorporate organic reactivity into the resin matrix. The new material is used as a substitute for a portion of the crosslinker, where, in addition to improved flexibility, good recoatability and pencil hardness are retained. Another new area is the development of liquid silicone resins, which enable formulators to create low-VOC products with unique functionality, including organic resin compatibility, flexibility and thermal stability. „Our target is stability“ than just grinding media product process analysis product training SiLi in-house and / or customer on site service bead recycling Silicone Elastomers Silicone elastomers are rubber-like materials used in elastomeric applications to provide water resistance, mar resistance and a matte finish. Available in aqueous and nonaqueous products, they can also impart texturing properties to countless formulations as well. Siliconates Siliconates are water-based solutions used to form low-VOC, breathable, water-repellent coatings (Figure 6). They are widely used in damp-proof exterior facade applications. Methyl siliconates react with carbon dioxide to form water-insoluble silicone resins. These materials are also used in penetrating, low-VOC, breathable water-repellent applications. In addition, silicates and siliconates are used to provide surface protection from moisture and water. Pore-blocking sealers form a resin barrier on a concrete surface. While they partially or fully fill surface pores, they do not penetrate the material deeply. On the other hand, hydrophobic sealants do, allowing the concrete to breath, and can be added to the mix pre-cure. Both solutions meet specific market needs and allow formulators more flexibility when deciding upon the right answer to their needs.
