【Product Overview】
Nogawa Chemical DIABOND® DA3110LL high-performance transparent adhesive
DIABOND DA3110LL is a high-performance single-component transparent adhesive developed by Japan's Nogawa Chemical specifically for the bonding of electronics, micro-components and engineering plastics. This product has been specially designed for difficult-to-stick materials such as soft polyvinyl chloride (soft PVC) and polyurethane (PU) that contain a large amount of plasticizers, and has excellent Resistance to plasticizer migration and erosion With high initial bonding strength, the film has high transparency, flexibility and shock resistance. It performs well in the assembly of micro speakers, receiver parts and precision industrial bonding.
【Core features and advantages】
Outstanding plasticizer resistance: For soft PVC rubber, artificial leather and polyurethane materials, the cured adhesive film will not become sticky, soften or degummed, and has excellent long-term bonding stability.
High transparency and aesthetics: After curing, the adhesive film is clear and transparent, and the adhesive overflow will not turn yellow or be conspicuous. It is especially suitable for the assembly of precision appearance parts and optical/electroacoustic devices.
Strong initial viscosity and good operability: The surface stem is positioned quickly, has a suitable opening time, breaks the wire cleanly without drawing, and is suitable for manual gluing and fine dispensing operations.
Temperature and shock resistance, flexible and durable: The adhesive layer has good ductility and elastic buffering force, can effectively absorb drop impact and vibration stress, and has excellent water resistance, cold resistance, and aging resistance.
Broad substrate adaptability: Extremely high adhesion to soft/hard PVC, polyurethane (PU), ABS, polycarbonate (PC), rubber, leather, fabric and metal sheets.
【Typical application areas】
Micro electroacoustic and communication accessories: Mobile phone receiver (Receiver), positioning of micro-speaker/speaker parts, auxiliary fixation of diaphragm edge and outer frame, etc.
Electronic appliances and precision assembly: Precision plastic shell, sensor sealing and fixing, various types of buffer and anti-vibration pads and structural fit of soft components.
PVC / PU industrial composite: Soft PVC film, artificial leather, polyurethane foam materials, fabrics and high-strength composite adhesion of rubber and metal.

[Usage Guide and Process Suggestions]
Substrate cleaning: Thoroughly clean the surface of the workpiece to be bonded, remove grease, release agent, dust and moisture, and keep the surface dry.
Apply adhesive evenly: Use a brush, dispensing syringe or scraper tool to apply evenly on the bonding surface (double-sided coating provides the best bonding strength).
Leave to dry: Leave at room temperature for approx.3-8 minutes, wait for the solvent to evaporate appropriately until the film is slightly sticky but not stringy, then align the position and fit it.
Pressure fastening: After bonding, apply appropriate and uniform pressure to eliminate air bubbles, and the workpiece can obtain excellent initial positioning strength. Leave it at room temperature for 24 hours to achieve the highest final bonding strength.
[Storage and Safety Precautions]
Fireproof and antistatic: This product contains volatile organic solvents. Fireworks are strictly prohibited in the workplace. Maintain a good ventilation and ventilation environment.
Airtight storage: Please tighten the seal of the container after use to prevent the solvent from evaporating and causing the adhesive to thicken and form a skin; place it in the 5°C-30°C Store in a cool, dry place away from light.
Cleaning instructions: Use special thinner, ethyl acetate or toluene solvent to clean tools or wipe excess adhesive.
