What Is UV Cure Glue?
Is UV Glue under valued glue?
UV cure glue, is possibly one of the most underrated glues around, but if you are looking for a quality supplier of UV cure glue and the best advice on using UV cure glue….read on!
First of all, let us look at what it is. UV cure glue is based on acrylic resins, which upon exposure to a particular light wavelength, cure to form very structurally strong bonds.
The UV lights which are used for curing emit ultraviolet light within wavelengths ranging from 320 to 400 nanometers. When the UV glue is exposed to this light, a photochemical reaction takes place which causes the glue hardening process. To ensure adequate penetration of the shorter wavelengths of the UV light, at least one of the objects being glued must be transparent.
We currently market four different UV glues and depending on the type, bonding may occur immediately or several minutes after the parts have been united.
Let us take a look at the equipment which is used to cure UV glue. This type of equipment can range from simple hand held lamps, to lamps mounted on conveyors. The choice of equipment depends on various factors, including the size of the parts being glued, and the exact fabrication method. One important factor in the use of UV glue, is the quality of the UV lamps. These lamps should be ideally last for up to 3,000 hours. After this time, the wavelength diminishes in capacity.
Remember, the wavelength of the UV light necessary for adequate curing may cause damage to skin and eyes. The best way to block the harmful UV-A radiation, is to wear goggles and cotton gloves. Exposed skin should be protected and we can advise on the optimum personal protective equipment. If I was to offer some basic tips for using UV glue, what would they be?
- Bottles of UV glue should be capped after use and always stored in a dark place.
- The UV light source should be placed as close as possible to the parts being bonded.
- Thick materials, such as thick pieces of glass, will take longer to cure.
- The lamps should be checked on a monthly basis.
Our UV glues provide for a strong bond when used to join glass to glass, glass to metal, glass to some plastics etc. They are available in various pack sizes, the most common being 50 ml and 250 ml.
Don’t underestimate UV glue. In many applications, it’s the best choice!
Our Laboratories and Sales Department, are always available to help you with any UV glue bonding process.
