What is the meaning of UV Curing Paint?

UV curing paint is a coating paint that is cured with ultraviolet light, this is different from thermo setting that requires heat. However, it carries photoinitiators which when the coating is exposed to UV light will lead to polymerization and immediate solidification of the coating. The technology of UV curing can be implemented in surface treatment of various materials since it is fast and environment friendly for application on the PVC marble sheet.

When carrying out UV-coated sheets, high-quality substrates are used, and commonly the base material is PVC marble sheet. Finally, the surface is coated with a material given that upon exposure to ultra violet light, the material cures and forms a protective layer of great durability and attractive look. This process also increases the ability of that surface to withstand wears and unable to get stained while having a lasting glossy look.

The video demonstrates the difference between two test samples: the first one coming with a coat UV curing paint and the second one without the coating.

Take a brief look at the production process of PVC Marble sheet.

In the video, the curing process of the UV-coated PVC marble sheets under an ultra violet light is demonstrated. A good number of manufacturers omit this step in order to cut down on their expenses. At times you may accidentally come across a product that is embroiled in such controversy; you will be in for a rough time.

Concerning the use of UV curing paint in creating PVC marble sheet, surface treatment is the most affected province. Here are the detailed steps:Here are the detailed steps:

  • Substrate Preparation:Ready the materials needed for the process which is the PVC sheets that are made of polyvinyl chloride blending others or extruded and calendered.Examine the PVC sheets and measure them according to the desired size then saw them into those sizes and make sure that the surfaces are free from debris and dust.
  • Primer Coating:To improve the bonding of the UV curing paint to the PVC substrate, coat the surface of the PVC sheet with a layer of primer.The primer is generally meant for the specific application on PVC materials in order to achieve good bonding as well as coating.
  • Pattern Printing:Once the primer surface dries up, with the help of high-caliber printing machine, print marble newspaper designs on the surface of the sheet of PVC.It is possible to orient the choice of patterns depending on the customer request and reproduce appearance and structure of different types of marbles.
  • UV Curing Paint Application:Afterwards the pattern printing is done, apply paint of UV curing on the surface of the PVC sheet uniformly in one layer.This UV coating assists in affording protection and at the same time increasing its surface shine thus enabling the marble sheet to having a higher class look.
  • UV Curing:Once the UV paint has been applied on the PVC sheets, it is recommended that you expose the sheets to a UV curing equipment.The UV curing equipment releases UV light of certain wavelengths which on interacting with photoinitiators in the UV paint leads to cross-linking and quick curing of the coating.
  • Quality Inspection:After the curing process is undergone, examine the PVC marble sheets for defects, and to check if it has some bubbles, scratches or is not clear as the pattern used.

Benefits of UV Curing Paints to the PVC Marble Sheet

  • Rapid Curing:Curing by UV paint cools very fast and within a few seconds so that productivity is enhanced.
  • Environmentally Friendly: he UV curing process involves no emissions of solvents to the atmosphere thus considered as an environmental friendly technology in surface treatment.
  • High Hardness and Wear Resistance:The cured coating is very hard and shows very good wear resistance and scratch resistance this in turn increases the life span of PVC marble sheets.
  • Excellent Gloss:UV curing paint offers high reflexive which in return makes the surface of the PVC marble sheet to look more attractive & bright.
  • Strong Adhesion:That’s why, during the primer treatment and using UV curing, the coating does not peel and stick tightly to the PVC substrate.

Which Kind of UV Board Is the Best, in Conclusion?

With the above information understood, one is supposed to have gained improved understanding of PVC marble sheet. For those of you, who need highly durable, but relatively cheap PVC marble sheet, do not hesitate to contact us.
