Factors to Consider When Selecting Oligomers (UV Resins) for Light-Curing Coatings

Factors to Consider When Selecting Oligomers (UV Resins) for Light-Curing Coatings

The selection of oligomers (UV resins) in UV-curable coatings is a critically important step in the coating manufacturing process. When choosing oligomers, several factors must be taken into account to ensure that the coating’s performance and cost are optimized. In practical applications, the selection should be made based on actual needs to achieve the best coating results.

Applications of Visible-Light Initiators

Applications of Visible-Light Initiators

Visible-light initiators are a class of compounds capable of absorbing visible light and releasing free radicals or ions. They are widely used in fields such as UV-curable coatings, inks, and adhesives. In the application of visible-light initiators, they can accelerate the progression of photocuring reactions, thereby enhancing both the production efficiency and quality of the final products.

Common Problems and Solutions in the Use of UV Varnish

Common Problems and Solutions in the Use of UV Varnish

UV varnishes pose two main challenges for packaging and printing plants: First, they are sensitive to operating conditions during seasons with high temperatures and humidity; second, they are vulnerable to excessive moisture content in the substrate. Under these workshop conditions and given the nature of the substrates, the ink or adhesive films applied during printing or varnishing are highly likely to peel off when initially inspected using adhesive tape, leading to product returns by customers. In addition, there are numerous common issues associated with the use of UV varnishes. What are the primary causes behind these problems? What are their direct manifestations? And what are the effective solutions?
