Application scope of UV-curing (UV) anti-crater additives


1. Coatings

Wood coatings

Applied in UV wood coatings to prevent craters caused by wood surface texture or oil stains, and improve the flatness and glossiness of the paint film.

Examples: UV wood floor paint, furniture surface coating.


Plastic coatings

For plastic substrates such as PC, PMMA, ABS, etc., solve the crater problem caused by low surface energy and poor wettability.

Example: UV coating of 3C product shells (such as mobile phones and tablets).


Metal coatings

In UV coating of metal surfaces, prevent craters caused by metal oxidation or surface tension differences, and enhance coating adhesion.

Examples: Automotive metal accessories, metal packaging coatings.


Glass coatings

Used in UV glass coatings to prevent craters caused by the hydrophilicity of the glass surface and improve decorative effects.

Examples: Architectural glass, glassware coatings.


2. Ink field

Screen printing ink

In screen printing of substrates such as film, plastic, and metal foil, ensure uniform ink spreading and avoid shrinkage.

Examples: packaging labels, electronic product logos.


Flexographic ink

Applicable to flexographic printing processes such as film and labels to prevent shrinkage caused by deformation of the substrate or uneven tension.

Examples: food packaging, daily chemical product labels.


Offset ink

In UV offset printing, improve the transferability and leveling of ink and reduce shrinkage caused by paper surface roughness.

Examples: high-end brochures, leaflets.


3D printing ink

In UV curing 3D printing, prevent interlayer shrinkage and improve printing accuracy and surface quality.

Examples: industrial prototypes, dental models.


3. Special application areas

Optical coatings

Used for UV coatings such as optical lenses and prisms to prevent light scattering caused by surface defects.

Examples: eyeglass lenses, camera lenses.


Electronic coating

In UV coating of PCB, electronic components, etc., prevent shrinkage caused by surface contamination of substrate, improve insulation and weather resistance.

Example: mobile phone circuit board, sensor coating.


Textile coating

In UV-cured textile coating, prevent shrinkage caused by fabric fiber structure, improve coating wear resistance and feel.

Example: outdoor tent, functional fabric.


4. Industry application

Packaging industry

UV ink and coating for food packaging and pharmaceutical packaging, prevent shrinkage from affecting printing quality and safety.


Automotive industry

UV coating for automotive interior and exterior parts, improve surface quality and weather resistance.


3C electronics industry

UV coating for mobile phones, tablets, and wearable devices, prevent appearance defects caused by shrinkage.


Construction industry

UV-cured architectural coatings and glass coatings, improve decorative effects and durability.


Summary

UV-cured anti-shrinkage additives have a wide range of applications, covering coatings, inks, special coatings and multiple industrial fields. Its core value lies in reducing surface tension, improving leveling, solving the shrinkage problem caused by substrate differences, surface contamination or formula incompatibility, thereby improving product appearance quality and performance. With the popularization of UV curing technology, the demand for anti-shrunk crater additives in the field of high-end coatings will continue to grow.
