Product Overview

UV Screen Printable Peelable Mask Adhesive

3769C is a blue-purple, UV-curable screen printable peelable mask designed for temporary surface protection of glass, plastic and metal. It cures fast with excellent surface-dry (tack-free) performance, delivers outstanding screen printing efficiency, and forms a tough yet easily peelable film that leaves no residue, keeping the protected surface clean and intact throughout processing and handling.

Key Features

• Fast curing, excellent surface dryness - quick UV cure at 600 mJ/cm² with superior tack-free surface performance
• Tough film, easy to peel - 85 Shore A with 200% elongation for a durable yet easily removable protective film
• No residue, high cleanliness - the mask peels off cleanly without leaving adhesive residue on the substrate
• Excellent screen printability - smooth printing behavior and high printing efficiency for mass production
• Multi-substrate protection - suitable for temporary surface protection of glass, plastic and metal
• Clear visual inspection - blue-purple color makes the printed mask coverage easy to inspect

Technical Specifications

Product Applications

3769C is applied by screen printing as a temporary peelable protective mask on component surfaces. Typical applications include:

• Glass surface protection - screen printed mask protects glass surfaces from scratches, contamination and process damage during handling and downstream processing
• Plastic surface protection - temporary protection for plastic parts and panels during manufacturing and assembly
• Metal surface protection - shields metal surfaces and finishes from scratches, fingerprints and mild process exposure
• Selective area masking - screen printing forms precise mask patterns to protect selected areas while leaving others exposed
• High-efficiency printing - optimized rheology delivers high screen printing speed and consistency for volume production
• Clean removal - after protection is no longer needed, the tough film peels off easily without residue for high cleanliness

Frequently Asked Questions
