Silicone Coating for Vacuum Stages | Solving Transport Issues of Adhesive Materials
"Precision construction that does not block fine vacuum holes" eliminates label pickup errors with excellent release properties! It prevents adhesive sticking and improves line directivity.
This is a technical case study of a silicone-based non-adhesive coating applied to a metal suction stage (vacuum stage) that temporarily holds and transports labels in various manufacturing and packaging lines where automatic label application devices operate. The coating is applied uniformly and precisely without blocking the numerous fine suction holes (vacuum holes) provided on the stage surface. **Main Improvement Effects from Implementation:** - **Balancing Vacuum Fixation and Smooth Release (Pickup):** During transport, the labels are securely held by suction, and at the time of application, they are instantly released due to the excellent release effect of silicone. This prevents labels from sticking or being dragged along. - **Reducing Transport Errors by Preventing Adhesive (Glue) Adhesion and Accumulation:** The adhesion and accumulation of glue seeping from the edges of the labels are suppressed for a long time. This minimizes transport troubles such as dragging due to glue residue, supply errors, and positional misalignment, thereby increasing the straight-through rate of automated lines. - **Preventing Clogging of Suction Holes and Reducing Cleaning Workload:** Since adhesive is less likely to adhere, the effort and time required for solvent-based wiping cleaning are significantly reduced. This shortens the downtime associated with maintenance.
basic information
【Construction Technology】 Silicone-based Non-Stick Coating "NonStick Coating" Contract Processing 【Technical Features and Functions】 ■ High Non-Stick and Release Properties Effectively blocks adhesion and sticking of label adhesives (acrylic-based, rubber-based, etc.). Achieves reliable adhesion retention of labels and smooth release (pickup). ■ Durable Adhesion Strongly adheres to metal substrates and is designed to be resistant to peeling even under friction from high-speed continuous adhesion and transport. In addition to the standard type, a solvent-resistant type that withstands cleaning agents such as alcohol is also available. 【Target Substrates and Applicable Parts】 ■ Vacuum stages for automatic label application, suction plates, vacuum pads, guide plates ■ Various metal parts such as aluminum, stainless steel (SUS), and steel.

【Main Application Areas and Devices】 ■ Automatic Packing and Packaging Labeling machines (labelers), automatic seal application lines ■ Electronics and Precision Instruments Automatic suction transport of IC tags, substrate protection labels, and barcode seals ■ Food, Pharmaceuticals, and Daily Necessities Automatic labeling devices for bottles and containers, tray transport suction parts 【Problem Solving Case Study】 ■ Issue In the automatic labeling device, adhesive (glue) that seeped from the edges of the labels adhered to the surface of the vacuum stage, causing the labels to be pulled towards the stage during application, resulting in frequent misalignment and supply errors. Additionally, the adhesive entered the fine vacuum holes, causing clogging, and the long cleaning times required led to significant equipment downtime. ■ After Implementation Silicone coating "NonStick Coating" was applied to the entire surface of the vacuum stage. ■ Effects and Results - Adhesion and sticking of glue were significantly reduced without compromising vacuum suction power, eliminating label transfer errors. - The effort required for cleaning and clogging of vacuum holes was greatly reduced, improving the continuous operation rate of the equipment.

Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
