Tape 3850C

Details

Application Scenarios

Tape 3850C is a silicone-based adhesive tape designed for light to medium-duty applications requiring reliable performance and moderate temperature resistance.

Electronics Assembly & Masking: Suitable for temporary component fixing, wire harnessing, and protective masking during soldering or coating processes in PCB and electronic device manufacturing, given its 180°C heat resistance.

Surface Protection in Precision Industries: Its clean-removing silicone adhesive makes it ideal for protecting delicate surfaces (e.g., display panels, polished metals, plastic lenses) from scratches, dust, and contamination during handling, machining, or transportation.

Lightweight Bonding & Laminating: Can be used for bonding lightweight materials, such as nameplates, decorative films, foam sheets, or graphic overlays, where a balance of adhesion and removability is desired.

General Purpose Fixation: Applicable for securing temporary labels, holding parts in place during assembly, or bundling lightweight items in both industrial and office environments.

Product Description

The 3850C is a single-sided silicone pressure-sensitive adhesive tape featuring a green polyester (PET) film backing. It is engineered to provide a consistent balance of adhesion, temperature tolerance, and clean removal characteristics.

Key Features:

Moderate Heat Resistance: Capable of withstanding temperatures up to 180°C for 30 minutes, accommodating a variety of light industrial and electronic assembly processes.

Silicone Adhesive System: Offers stable adhesion to various surfaces and is formulated for relatively clean removal, minimizing adhesive residue on substrates.

Robust PET Backing: The polyester film carrier provides good tensile strength (15 kg/25mm), dimensional stability, and resistance to tears and chemicals.

Predictable Performance: With specified adhesion (0.6-0.8 kg/25mm) and initial tack (>15 NO/BALL#), it delivers consistent and reliable handling properties for process control.

Standard Manufacturing Format: Supplied on a 3-inch polyethylene core, with precise width (1020mm) and length (66m) tolerances, suitable for automated dispensing and die-cutting equipment.

End-users are advised to conduct tests under their specific application conditions to ensure the tape meets all performance requirements for the intended substrates and operating environment.
