Surface treatment technology: What is the difference between "silicon" and "silicone"?
MRS coating
Silicone," which excels in non-stick and release properties. We will introduce the differences from the easily confused "silicon" and "silicone coating.
■Differences Between Silicon and Silicone Silicon (Silicon) and silicone (Silicone) are completely different substances, but they are often confused in writing. "Silicon" refers to the element with atomic number 14, silicon (Si), which is used as a material for semiconductors and solar cells. On the other hand, "silicone" refers to synthetic resins such as "silicone resin" or "silicon resin." Silicone is a synthetic polymer with a basic structure of siloxane bonds, combined with organic groups, and is used in various forms such as oils and rubbers. ■Silicone with Excellent Non-Stick and Release Properties Silicone has characteristics such as low surface tension, excellent water repellency, high heat resistance, and chemical stability. Additionally, silicone is used as a release agent, demonstrating excellent release properties by virtue of its low surface tension and its ability to transfer to the material it interacts with. ■Silicone Coating While silicone release agents exhibit excellent release properties, they may sometimes have challenges with durability. Some silicone coatings achieve a balance between excellent release properties and durability, aiding in the improvement of production equipment and processes. ▼For more information on the innovative silicone coating 'MRS Coating,' click here!

basic information
■MRS Coating (Mold Release Silicone) Exhibits excellent release properties against sticky substances and adhesive tapes. This non-stick, release coating is packed with features not found in conventional silicone coatings. The smooth surface makes it easy to wipe off dirt and facilitates cleaning. Even when cleaned with solvents, the release properties remain largely unchanged. *Based on our comparative tests. ■Part of the lineup MRS-102 → A release coating with excellent solvent resistance that maintains its effectiveness even after cleaning with solvents. MRS-014 → A high-hardness thin film coating that preserves shapes like blades and embossing. MRS-004 → A rubber-like heat-resistant coating with heat resistance exceeding 200°C, comparable to fluororesins. (Release properties remain after 16 hours at 350°C) MRS-200 → Can be heated at low temperatures below 80°C, suitable for resin and rubber products. ■Features - Smooth surface without unevenness, easy to wipe clean - Can be cleaned with solvents - Thin film that hardly alters the shape of the substrate - Heat-resistant despite being silicone-based - Processable for resin and rubber (low-temperature processing)
