Service Details

Description

SQ-710003 is a one-component UV-curable adhesive that is formed on the surface of PC, PET, TPU and other films through molds with various textures and structures. Small molds can be manually transferred to the film surface in batches, or automated, high-capacity structural rollers or textured film transfer can be used. It is mainly used to make texture decoration and shell molding for mobile phones, laptops, home appliances and other products. The product has the characteristics of good demoulding performance, high hardness, good plating properties, excellent recoating performance and UV aging resistance.

Chemical & physical data

Performance

Delicate matte effect, good hand feel, good scratch resistance

Good resistance to yellowing and good transparency

It has good stretchability and low shrinkage. After curing, it forms a flexible protective layer. The film thickness can be 10-100um. The adhesive layer will not crack, bend or fall off when bent at 180 degrees.

It has good resistance to high and low temperatures, high humidity, chemical solvents, moisture resistance, and UV resistance. The product performance remains stable in harsh environments.

Application

Texture decoration and shell molding of mobile phones, laptops, home appliances and other products.

Construction technology

1. Clean the material surface.

2. Pour the glue into the metal mold, fit the PC or PET to the metal mold, and use a glue stick to squeeze the surface of the material so that the glue can expel air bubbles and achieve better leveling. Make sure that the bonding parts are covered with glue.

3. Irradiate with ultraviolet light with a wavelength of 265 or 395 nanometers. When irradiating, keep the UV lamp as close to the glue as possible to speed up the curing.

4. Tear off the PC or PET from the metal mold. At this time, the adhesive layer is completely peeled off and stuck to the surface of the PC or PET.

5. If the adhesive layer is not completely cured, you can continue to use UV light until the adhesive layer is fully cured.

Attention

1. Ensure that the UV adhesive layer absorbs sufficient UV energy to achieve the curing effect, otherwise it is easy to affect the performance of the adhesive layer.

2. The remaining glue shall not be returned to the original packaging. It shall be sealed away from light and stored at room temperature.

Storage, shelf time and Packing

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-710003 wear-resistant matte UV transfer glue, with fine matte effect, good hand feel, good scratch resistance and low viscosity.
