Matte UV Varnish

Matte UV varnish is an advanced light-curing coating that uses ultraviolet (UV) light curing technology and is widely used in printing, packaging, electronics, furniture and other fields. Unlike traditional glossy coatings, this UV coatings present a soft gloss, which can effectively reduce reflections and enhance the texture and visual appeal of the product.

Product Introduction

Product Features

Matte effect: Compared with glossy UV coatings, matte UV varnishes have lower gloss, presenting a soft and non-glaring visual effect, with a unique texture, which can meet consumers' requirements for low-key and elegant appearance.

Good wear resistance: After UV curing, the coating forms a cross-linked structure with high hardness and good wear resistance. It can effectively resist friction, scratches and other damage in daily use, and protect the surface of the coated object.

Fast curing speed: The characteristics of UV curing technology determine that matte UV finish can be quickly cured in a short time, greatly improving production efficiency and suitable for large-scale industrial production.

Strong chemical resistance: It has good resistance to chemicals such as acids, alkalis, and salts, and is not easily corroded by chemical substances. It can maintain the stability and integrity of the coating.

Good environmental protection: no volatile organic compounds (VOC) are produced during the UV curing process, or the VOC emissions are extremely low, which meets environmental protection requirements and has little impact on the environment and human health.

Quality Inspection

Appearance inspection: Check the appearance of the cured matte UV varnish to ensure that the surface is flat, free of bubbles, sagging, particles and other defects.

Gloss detection: Use a gloss meter to detect the gloss of the coating to ensure that it meets the matte requirements.

Adhesion test: Use the cross-cutting method, tape sticking method and other methods to test the adhesion of the coating to ensure that the coating is firmly bonded to the substrate.

Hardness test: Use a hardness tester to test the hardness of the coating to evaluate the wear resistance and scratch resistance of the coating.

Packaging and storage

Packaging: Package the products that have passed the quality inspection to protect the coating surface from damage. The packaging materials can be selected according to the requirements of the product. Suitable plastic bags, cartons, wooden boxes, etc.

Storage: Matte UV finish products should be stored in a cool, dry, well-ventilated place, avoiding direct sunlight and high temperature environment. The storage temperature is generally between 5℃-25℃, and the storage period depends on the characteristics of the product and storage conditions.

FAQ

Q: How durable is matte UV coating?

A: Matte UV finish has excellent wear resistance and chemical resistance, can resist corrosion from a variety of chemicals, and is suitable for high-frequency contact environments.

Q: What are the restrictions on materials coated with matte UV varnish?

A: Although matte UV finish is suitable for a variety of materials, it has poor adhesion to some non-polar plastics (such as polyethylene and polypropylene), and surface treatment is required before use.

Q: How to evaluate the curing effect of matte UV finish?

A: You can check whether it is dry and hard by touching the surface of the coating; using adhesion test tape can evaluate whether the adhesion of the coating is qualified.

Q: How safe is matte UV coating on food packaging?

A: If used for food contact materials, you must choose UV coatings that meet food safety standards and follow relevant regulations.

Q: How should UV coatings be cleaned and maintained?

A: When cleaning, use a mild detergent and soft cloth, and avoid using highly corrosive or abrasive cleaning products to protect the coating surface.
