1. Core Construction: The base material is non-woven fabric coated with polyacrylate pressure-sensitive adhesive on both sides. An outer silicone-coated double-sided film serves as the isolation layer, forming a stable structure of "isolation layer-adhesive layer-base material-adhesive layer-isolation layer". The Gray Mark Double Sided Tape of Yongda features a uniform gray appearance, tightly rolled without adhesive leakage, and carries a subtle natural scent of industrial adhesive.
2. Core performance characteristics: Strong initial adhesion, can quickly adhere to the object; excellent holding adhesion, high 180° peel strength, long-term adhesion is not easy to fall off; chemical properties are stable, no substantial health damage to the human body, insoluble in water, only in organic solvents will the gel layer swelling phenomenon occurs.
3. Safety and Compatibility: Not classified as hazardous waste, it is non-flammable but should be kept away from open flames and high heat. The flexible adhesive can adhere to curved or irregular surfaces. Some individuals may be allergic to the adhesive components, so skin protection is recommended.
1. Stable performance meets standards: Key indicators such as width, thickness, and adhesion all comply with corresponding national standards. Core data like initial adhesion (measured at 20/20 meets the standard of No.20 steel ball) and peel strength (measured at 10.8/9.6N/24mm) exceed basic requirements, ensuring reliable adhesion.
2. Eco-friendly and safe disposal: The Gray Mark Double Sided Tape of Yongda uses environmentally friendly non-woven fabric base material and polyacrylate pressure-sensitive adhesive, with no harmful additives. After disposal, it can be disposed of through incineration, deep burial and other conventional methods, in line with environmental protection regulations, and reduce the cost of waste disposal.
3. Wide application scenarios: Flexibility and adhesion are suitable for a variety of processes in the packaging industry, such as goods fixation and component bonding in the electronic and electrical industry. It can not only meet the requirements of planar bonding, but also adapt to the bonding scenarios of irregular surfaces.
4. Easy storage and use: Just store in a cool and well-ventilated warehouse, away from fire and heat sources. Avoid direct sunlight in summer to maintain stable performance. The matching silicone film isolation paper is easy to peel off, efficient to use, and does not affect the adhesive surface.
1. Raw material pretreatment: Screen non-woven fabric substrates meeting specifications to ensure adequate toughness and porosity; prepare silicone-coated double-sided film paper to verify its peel strength and impact resistance; prepare pressure-sensitive polyacrylate adhesive and adjust viscosity parameters to acceptable levels.
2. Two-sided adhesive coating process: Through professional adhesive coating equipment, polyacrylate pressure-sensitive adhesive is evenly coated on both sides of non-woven fabric, and the thickness of adhesive coating is strictly controlled to ensure no leakage, uneven thickness and other problems, and enhance the bonding strength between the adhesive layer and the substrate.
3. Composite molding: Align the adhesive-coated non-woven fabric with the double-sided lamination paper and composite them precisely, ensuring the isolation paper and adhesive surface are tightly attached while avoiding bubbles and wrinkles, guaranteeing the product's regular shape.
4. Winding, Cutting and Inspection: Wind the Gray Mark Double Sided Tape of Yongda to 1240mm×50m specifications, ensuring tight and secure winding. Conduct sampling tests on finished products for width, thickness, adhesion and other parameters. Only products meeting these standards may be stored for sale.
1. Appearance specifications: The color is uniform gray, the surface is flat and free of impurities, the adhesive layer is free of overflow, and the isolation paper is peeled smoothly.
2. Dimensional parameters: width 1240mm, permissible deviation ±2.5mm; length 50m, actual length not less than the marked length; total thickness 114μm, permissible deviation ±5μm.
3. Performance specifications: Initial adhesion ≥14# steel ball (measured to 20# steel ball standard, 20/20 passed); 180° peel strength ≥8N/24mm (measured at 10.8N/24mm, 9.6N/24mm); Adhesion retention>24h/24×24mm.
4. Technical specifications: Width and length comply with GB/T32370-2015; total thickness meets GB/T7125-2014; initial tack follows GB4852-2002 (Method A); peel strength conforms to GB/T2792-2014; and tack retention adheres to GB/T4851-2014.
1. Packaging and printing industry (high frequency practical scenarios)
1. Gift box and color box packaging: used for high-end gift boxes and cosmetic packaging boxes for wallpaper and sealing. The gray appearance can be matched with dark or neutral color packaging, hiding the adhesive marks and improving the packaging refinement.
2. Label and identification adhesion: Suitable for product packaging label fixation, such as logistics label, anti-counterfeiting identification, qualification certificate adhesion, etc.
3. Buffer Material Adhesion: In packaging of fragile items (such as glassware and ceramic products), EPE foam, bubble wrap, and other cushioning materials are adhered to the inner walls to provide all-around protection.
2. Industrial manufacturing (general support scenario)
1. Hardware and Plastic Adhesive Bonding: This method secures hardware components (e.g., hinges, handles) to plastic casings, replacing traditional screw fastening to prevent surface damage from drilling. The adhesive layer resists mechanical stress, withstanding minor impacts and pulls during daily use.
2. Temporary Fixing and Positioning: This system provides temporary positioning and securing for components during mechanical assembly and mold production processes, facilitating subsequent operations such as welding and bolt tightening. The removable design leaves no adhesive residue on metal or mold steel surfaces, significantly reducing post-production cleaning costs.
3. Home and decoration (everyday practical scenarios)
1. Home furnishing assembly: For assembling and securing small furniture (such as shelves and storage boxes) and installing wall hooks and shelves without drilling holes. The gray appearance blends with most interior styles and is discreetly concealed after application.
2. Soft decoration and decoration fit: used for curtain hanger fixing, carpet edge trimming, wallpaper repair, etc. Its flexibility can adapt to soft materials such as fabric and paper, and it is not easy to produce wrinkles when sticking, and its adhesion lasts in a dry environment.
4. Automotive interior (extended adaptation scenarios)
1. Interior trim mounting: Suitable for attaching small car accessories like sun visor clips, air vent diffusers, and phone holders. The adhesive layer withstands extreme temperatures from-20°C to 60°C, ensuring durability in both scorching heat and freezing cold.
2. Interior gap repair: used for the repair of interior cloth and leather edge lifting in car door panels, center console and other parts. Gray is compatible with most car interior tones. After sticking, the gap can be hidden and the interior tidiness can be restored.
3. Temporary marking: During the car maintenance process, it is used to stick temporary maintenance marks and circuit marks, so that the maintenance personnel can identify them easily. After the maintenance is completed, it can be removed without residue and does not affect the original material of the interior.
Q1: What materials can I stick?
A: Compatible with metal, plastic, sheet metal, etc., especially suitable for nameplate, aluminum plate and other bonding scenarios.
Q2: Do you need to treat the surface of the object to be glued before sticking?
Answer: Keep the surface dry, clean, free of oil and dust to ensure the best bonding effect.
Q3: Can it be normally attached in low temperature environment?
Answer: Yes, the temperature resistance is excellent, and the basic viscosity can be maintained in the low temperature environment. It is recommended to apply pressure to strengthen after bonding.
