Applications of UV LED Light Sources in UV Varnishes, UV Adhesives and UV Coatings

1. UV-curable screen-printing varnish

It can be used for spot varnishing or full-surface varnishing. The varnished surface features vibrant, glossy and transparent colours with a photographic finish; it is wear-resistant, does not peel or curl, and is used for the decorative and protective finishing of high-end packaging.

Product features:

a. The product is odourless, solvent-free, causes minimal skin irritation and cures quickly.

b. The product has excellent defoaming and levelling properties, making it suitable for high-speed printing on automatic printing presses.

c. The product exhibits excellent adhesion and fold resistance on gold and silver cardstock.

d. The product’s viscosity is adjustable to suit screens of different mesh counts, making it suitable for printing on a wide range of wine boxes and cigarette packets.

2. UV plastic varnish (suitable for hot foil stamping)

Primarily used for roller coating on the surfaces of PE and PP films or sheets; suitable for gloss finishing on toothpaste tubes, PE tubes and self-adhesive film surfaces.

Product features: Resistant to yellowing, low odour, abrasion-resistant, high gloss and good flexibility. This range also includes a UV matt varnish.

3. UV varnish for CD protection

Disc protective film is a key material in disc production and is crucial to disc quality. It must adhere well to the disc’s reflective metal layer, be highly compatible with printing inks, perform well at both high and low temperatures, and offer excellent wear resistance. Our company, Shenzhen Deshengxing Technology, manufactures products that possess all these characteristics.

4. UV-curable adhesives

Features: A single-component UV-curing adhesive; UV-curing adhesives are not only easier to use than traditional two-component thermosetting adhesives, but also offer the following features.

Optical properties: The liquid crystal adhesive is crystal-clear; after curing, its light transmittance is ≥90%.

Adhesive properties: Low volume shrinkage after curing, high elongation and high adhesive strength.

Weather resistance: Once cured, the adhesive exhibits excellent weather resistance; it does not yellow when exposed to prolonged ultraviolet radiation and has high resistance to both high and low temperatures, making it suitable for use in a temperature range of –50 to 80 degrees Celsius.

Applications: For the rapid bonding of transparent materials such as transparent plastics, glass and metals, as well as non-transparent materials such as plastics, ceramics and rubber. The curing time can be as fast as one second, and the bond strength is adjustable. Suitable for bonding, encapsulation or mounting in applications such as optical discs, electronic components, optical communication devices, bioproducts and furniture.

a. UV disc adhesive: UV disc adhesive, suitable for the production of DVD-5 and DVD-10 discs.

b. Glass–aluminium alloy adhesive (UV-curing adhesive): Widely used in the optical instrument, medical device, craft, furniture and construction industries for bonding glass to metal, glass to glass, metal to metal and other such combinations.

Instructions for use: First, clean the surface of the object to be bonded thoroughly and allow it to dry. Apply a small amount of adhesive to the surface of the object to be bonded, then press the surfaces firmly together to remove any air bubbles from the adhesive layer, ensuring that the adhesive layer is less than 25 μm thick,

After application, cure the resin by exposing it to a high-pressure mercury lamp (power: 60 W/cm) at a distance of 10 cm for 10–20 seconds (curing times may vary slightly depending on the light-curing material and the lamp used). The properties of the light-curing resin will reach their optimum after half an hour.

5. UV-curable soft rubber

Uses: To provide a protective, transparent finish for trademarks, badges, labels, etc.

Features: The liquid adhesive is stable in storage and cures rapidly upon exposure to ultraviolet light; the cured adhesive is transparent and elastic, and is scratch-resistant; indentations and scratches disappear of their own accord.

Instructions for use: Once the resin has been dispensed, it may be placed in a light-curing oven for curing. The resin layer should not exceed 2 mm in thickness. Curing conditions: high-pressure mercury lamp, 60–80 M/cm; curing time: 10–25 seconds.

6. UV-cured marble-effect coating

UV marble varnish, used for decorating marble, engineered stone, ceramic stone and similar materials, provides a bright finish with a distinctive effect; it reduces energy consumption in stone production and improves production efficiency.

7. UV-curing adhesive

For bonding glass to glass, glass to metal, plastic to plastic, and plastic to metal.

Features: Fast curing, high bond strength, no yellowing, no bubbling. Cures within 20 seconds in sunlight.

Applications of UV LED Curing in Medical Devices

UV adhesive bonding facilitates the cost-effective, automated assembly of medical devices.

Today, advanced LED UV light source systems, capable of curing solvent-free UV adhesives in a matter of seconds, combined with dispensing systems, provide an effective and cost-efficient method for achieving consistent and repeatable bonding in the assembly of medical devices.

The optimisation and control of UV light sources are crucial for the manufacture of reliable medical devices. The use of UV-curable adhesives offers numerous advantages, such as lower energy requirements, savings in curing time and space, increased productivity, and greater ease of automation.

UV adhesives are generally used to bond and seal medical devices, which require exceptionally high quality and the utmost reliability.

UV adhesives are typically used in the assembly of medical devices, for example, where it is necessary to bond: 1) different materials (or materials with different mechanical properties); 2) materials that are not thick enough to allow the use of welding methods; 3) pre-manufactured sub-assemblies.
