On mobile phones and computers Battery label, graphite sheet, battery tape and also Black adhesive tape for under-display light blocking on smartphones In applications involving precision components, inks must not only deliver flawless masking and marking performance but also possess Extremely strong adhesion To withstand bending, high temperatures, and everyday abrasion, while also resisting fingerprints to maintain component cleanliness and assembly quality, we have specifically developed— for such demanding applications— Anti-fingerprint black ink CSKM-S25500 , safeguarding your product’s details with professional-grade performance.
Product Highlights Overview
● Specifically designed for precision components: Especially suitable for PET substrate The battery label, graphite sheet, battery tape, and under‑display black light‑blocking tape all exhibit excellent adhesion and long-lasting durability.
● Perfect score for 100-grid adhesion: Through rigorous grid‑adhesion testing, the coating remains intact at the edges after tape removal, ensuring that it does not delaminate during die‑cutting, lamination, or assembly.
● Fingerprint-resistant, keeps it clean: A specialized surface‑treatment formulation effectively reduces fingerprint adhesion, ensuring the battery label and light‑blocking tape maintain a clean, pristine appearance throughout assembly and transportation.
● Solvent-resistant and stable in performance: It exhibits excellent resistance to common cleaning and processing solvents such as alcohols and esters, and the coating performance remains stable after processing.
● Excellent construction adaptability: Supports intaglio printing, with viscosity that can be flexibly adjusted to suit production line conditions, thereby enhancing production efficiency.
Experimental on-site video demonstration
We have conducted rigorous professional testing and intuitively verified the reliability of the CSKM‑S25500 in real-world applications:
1. Anti-fingerprint test: After simulating finger contact, the surface remains residue-free, retaining a matte black finish.
2. Cross-Cut Adhesion Test: (For PET substrates): After cross‑hatching, the adhesive tape peels off with strong force, and the coating shows no lifting or delamination, demonstrating excellent adhesion.
3. Solvent Resistance Wiping Test: After repeated wiping with alcohol, there was no change in the coating’s color, gloss, or adhesion.
Technical Specifications Overview
Typical application scenarios
● Battery module ： Mobile phone/computer battery labels, printed graphite heat sinks, and battery‑fixing adhesive tape.
● Light-blocking and marking tape ： Black adhesive tape for under‑display shielding, camera privacy film, and internal identification labels.
● High-end electronic tags ： PET labels and membrane switches requiring high adhesion and fingerprint resistance.
Usage and Process Recommendations
● Surface cleanliness is key. ： Before application, be sure to thoroughly clean the PET substrate with alcohol or an equivalent solvent to remove release agents, oils, and other contaminants, ensuring optimal adhesion.
● Aging cannot be omitted. ： To achieve optimal wear resistance, solvent resistance, and adhesion, be sure to allow sufficient curing under the recommended conditions.
● Recommended for sample testing ： We recommend conducting small‑batch trials prior to use to ensure full compatibility with your specific substrate and production line conditions.
CSKM‑S25500 is more than just an ink—it is the guardian of the reliability and aesthetic appeal of your precision electronic components. We are committed to providing customers with stable, efficient, and environmentally friendly coating solutions, backed by proven performance, helping your products stand out in the market.
