SQ-710002 High Elogation UV Casting/Transfer Coating for Texture Trasnfer
Description
SQ-710002 is a single-component, UV-curable casting and transfer coating designed for forming patterns and textures on films such as PC, PET, and TPU. It can be applied using small molds for manual batch transfer, or via automated, high-throughput structured rollers or textured film transfer processes.
Widely used for decorative texture transfer and molded housings of consumer electronics, including smartphones, laptops, and home appliances, SQ-710002 offers excellent release properties, high hardness, good plating compatibility, superior recoating performance, and outstanding UV aging resistance. Its high elongation ensures flexibility and durability of the transferred coating, making it ideal for applications requiring both precision patterning and long-term performance.

Performance
Excellent elongation and flexibility; the coating can accommodate highly deformed parts without cracking while maintaining high transparency
High tear resistance; film thickness can range from 50–350 µm. The cured layer remains intact without cracking, deformation, or delamination even under 180° bending
Outstanding resistance to extreme temperatures, high humidity, chemical solvents, moisture, and UV exposure, ensuring stable performance under harsh conditions
Applications
Decorative texture transfer and molded housings for consumer electronics, including smartphones, laptops, and home appliances etc.
Application / Process Instructions
Surface Preparation
Clean the substrate thoroughly to remove dust, oil, or other contaminants.
Manual Transfer Process
2. Pour the UV adhesive into the metal mold, align the PC or PET film with the mold, and use a roller or spatula to press the adhesive evenly across the surface. This helps eliminate air bubbles and ensures full coverage of the bonding area.
3. Expose the adhesive to UV light with a wavelength of 265 nm or 395 nm. Position the UV lamp as close to the adhesive as possible to accelerate curing.
4. Peel the PC or PET film from the metal mold; the adhesive layer should fully release and remain adhered to the film surface.
5. If the adhesive layer is not fully cured, continue UV exposure until complete curing is achieved.
Production Process (Roll-to-Roll / Automated)
Unwind → Apply the casting coating onto specially treated release film → Mold roller pressing → UV curing → Demolding → Rewind → Ink printing → Slitting → Forming → Injection molding → Peel off polyester surface film → Apply hard coating
Precautions
1. Ensure that the UV adhesive layer absorbs sufficient UV energy to achieve the best curing effect, otherwise it will easily affect the performance of the adhesive layer.
2. Remaining glue cannot be returned to the original packaging and should be sealed away from light and stored at room temperature.
Storage
To prevent the product from polymerization and gelling, please keep it sealed and away from heat and light. Recommended storage temperature is not higher than 30°C. Unused products must be sealed and stored in a timely manner and cannot be stored in the open. Safe storage time is 6 months at room temperature( 25ºC) and under ventilation. 1KG/5KG/25KG/barrel
Tips: SQ-710002 High Elongation UV Casting/Transfer Coating offers excellent elongation and flexibility, ensuring no cracking on highly deformed parts. It provides high transparency and is easy to process, making it ideal for precision texture transfer applications.
