Quickly understand the 5 types of UV light curing adhesives

UV adhesives can be roughly divided into two categories: substrates (tape, double-sided tape) and no substrates (liquid glue).
The latter is cured by UV light when used, and the former can increase or decrease the viscosity by UV light.
Adhesive, UV-adhesive tape as temporary protection or temporary positioning, there is a great demand in the microelectronics, optoelectronic devices, such as wafers, touch screen glass processing industry.

UV Pressure Sensitive Adhesive (PSA)

PSA is currently prepared through solution coating, drying and chemical reactions.

PSA's products are in various forms, ranging from decorative films, various protective films to engineering structural tapes, and are used in a wide range of applications, including advertising boards, electronic products, and high-end packaging boxes.

UV compound glue

Food, beverages and some biomedical products require high-barrier flexible packaging, and the barrier properties of packaging materials determine and affect the edible time.

UV construction glue

Safety glass is mainly made of polyvinyl butyral film as the bonding material, and the glass sheets are bonded through the process of vacuum degassing and hot pressing.
The total production time takes about more than ten hours.
It has been a long time to produce laminated safety glass by using edge sealing, glue filling, and storage under natural light for tens of minutes to complete photopolymerization.
It has been a long time, but it is still a non-mainstream product and is mainly used in the low-end safety glass market.
The main reasons that liquid bonding methods are not widely accepted are the insufficient performance of UV glue and the lack of reliable data on safety.
The growth momentum of UV glue in the construction field is good.
Store kitchen windows and decoration, stained glass are all using UV glue.
With the improvement of performance, UV construction glue will have a great development.

In recent years, the application of PVC stone plastic flooring has been rapidly developed in China.
The construction method is to first scrape a layer of adhesive on the construction ground, and then glue the PVC floor.
PVC plastic floor glue can be divided into three categories: water emulsion type, solvent type, and reactive type.
The water emulsion adhesive uses water as the dispersion medium, and the product is non-toxic and low in cost.
However, the water resistance is poor.
Generally, after soaking in water, the adhesive force is greatly reduced, such as water-based acrylate.
Solvent-based adhesives are mainly polyvinyl acetate-based and neoprene-based adhesives.
The reactive type has polyurethane series adhesives.
This type of adhesive is required after application.

UV electronic glue

UV adhesives have been widely used in the field of electronic products, including cable positioning, pin sealing, liquid crystal panel preparation, mobile phone keys, etc.

UV optical glue

Touch screens are currently the largest single application of UV optical glue.

UV medical glue

UV adhesives have great room for growth in the medical field.
