What is the difference between UV resin and UV glue?
UV resin and UV glue are two different chemical. UV resin is an oligomer and is used as a solvent and coating, while UV glue is a prepolymer of 30-50% acrylate and is used as an adhesive.
1. UV resin, also known as photosensitive resin, is an oligomer that can undergo physical and chemical changes rapidly in a short period of time after being irradiated by light, and then cross-link and cure. It is a photosensitive resin with relatively low molecular weight, and has reactive groups that can carry out UV, such as unsaturated double bonds or epoxy groups.
UV resin is the matrix resin of UV coating. It is compounded with photoinitiator, reactive diluent and various additives to form UV coating, including UV water-based coating, UV powder coating, UV leather coating, UV optical fiber coating, UV metal coating Coatings, UV paper glazing coatings, UV plastic coatings, UV wood coatings, etc.
2. UV glue is composed of main components such as basic resin, active monomer, photoinitiator, etc., and auxiliary agents such as stabilizer, crosslinking agent, and coupling agent. Under the irradiation of UV light of appropriate wavelength, the photoinitiator quickly generates free agent or ion, which in turn initiates the polymerization and crosslinking of the base resin and the active monomer to form a network structure, thereby achieving the bonding of the bonding material.
UV glue is also called shadowless glue, ultraviolet curing glue, mainly used for glass to glass, glass to metal, plastic to metal, plastic to plastic, etc. Connecting, covering, protecting, sealing, bonding; bonding of intravenous injection tubes in medical supplies, bonding of injection needles and syringes, bonding of electronic diagnostic devices, etc., and other fields.
What is the classification of UV resin?
According to the different types of solvents, UV resins can be divided into solvent-based UV resins and water-based UV resins, solvent-based resins do not contain hydrophilic groups and can only be dissolved in organic solvents, while water-based resins contain more hydrophilic groups or hydrophilic chain segments, which can be emulsified, dispersed or dissolved in water.
1) Solvent-based UV resins: commonly used solvent-based UV resins mainly include: UV unsaturated polyester, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV pure acrylic resin, UV epoxy resin, UV silicone oligomer.
(2) water-based UV resin: water-based UV resin is soluble in water or water-dispersible UV resin, the molecule contains a certain number of strong hydrophilic groups, such as carboxyl, hydroxyl, amino, ether, acylamino, etc., but also contains unsaturated groups, such as acryloyl, methacryloyl or allyl. Water-based UV trees can be divided into three categories: emulsion, water-dispersible and water-soluble. There are three main categories: aqueous urethane acrylates, aqueous epoxy acrylates and aqueous polyester acrylates.
UV resin composition analysis shows that the main application areas are: UV ink, UV coating, UV glue, etc. Among them, UV resin is most used in UV coating, including the following types: UV powder coating, UV water-based coating, UV leather coating, UV fiber optic coating, UV paper varnishing coating, UV metal coating, UV plastic coating, UV wood coating, etc.
What are the characteristics of UV resin?
1) Higher light sensitivity.
Since SLA uses monochromatic light, this requires that the wavelength of the light-sensitive resin and the laser must match, i.e., the wavelength of the laser is as close as possible to the maximum absorption wavelength of the light-sensitive resin. At the same time, the absorption wavelength range of the light-sensitive resin should be narrow, so as to ensure that curing occurs only at the point of laser irradiation, thereby improving the accuracy of the production of parts.
2) Fast curing rate.
The general molding layer by layer curing with a thickness of 0.1 to 0.2 mm per layer, to complete a part to cure a hundred to thousands of layers. Therefore, if you want to create a solid in a short period of time, the curing rate is very important. The laser beam exposure time for a spot is only in the range of microseconds to milliseconds, which is almost equivalent to the excited state lifetime of the photoinitiator used.
3) Small dissolution.
In the modeling process, the liquid resin has been covering the cured part of the workpiece, and can penetrate into the cured parts and make the cured resin swell, causing the size of the part to increase. Only small resin swelling can ensure the accuracy of the model.
