What is UV curing?
UV curing is ultraviolet curing. UV is the English abbreviation of ultraviolet light. Curing refers to the process of converting substances from low molecules to high molecules. UV curing generally refers to the curing conditions or requirements for coatings (paints), inks, adhesives (glue) or other potting sealants that require ultraviolet curing. It is different from heating curing, adhesive (curing agent) curing, natural Curing etc.

The meaning of UV glue:
Ultraviolet curing technology (UV technology for short) is considered an environmentally friendly green technology, also known as 3E technology, which is energy saving, environmental protection, and economy. UV is ultraviolet Ultra-Violet ray. The abbreviation is the wavelength of This light of 200-450nm, of which UVA has a wavelength of 315-400mm; UVB has a wavelength of 280-315nm; UVC has a wavelength below 200-280nm; UVV has a wavelength of 200-100nm.

The composition, characteristics and curing principle of UV glue:
Chemical composition of UV glue: composed of oligomers, monomers, photoinitiators, and additives
UV glue performance characteristics: fast curing, controllable reaction, no solvent, no pollution; suitable for automated operations; wide bonding range, high bonding strength, wide range of uses; excellent optical properties; the colloid is colorless and transparent, and the transparency rate after curing is 290 %; Excellent weather resistance, non-yellowing UV glue curing principle and curing conditions: The photoinitiator (photosensitizer) in UV glue absorbs ultraviolet light under ultraviolet irradiation and generates active free radicals or cations, initiating monomer polymerization and cross-linking. The chemical reaction of coupling and grafting converts the adhesive from liquid to solid within a few seconds; UV glue must be cured under ultraviolet irradiation with a wavelength of 200nm~400nm.

Advantages of UV curable glue
Fast - Increase productivity
Solvent-free - no volatile, corrosive
Saves energy compared to heat curing
No heat cure stress
No need to mix
Reduce semi-finished products in the process

Factors affecting UV glue curing-UV glue
Components:
1) Single UV curing
2) Multi-mode curing (UV heating, accelerator...etc.)

Confirmation requirements:
Surface curing
Depth curing
Initial curing time

Safety precautions when using UV resind:
UV glue is a green, environmentally friendly and economical chemical product. It does not contain any organic solvents and is 100% solid content glue. It will not cause any toxic, carcinogenic or pathological hazards to the human body. The main components of UV glue are acrylic series oligomers and part of acrylic acid. Cool series monomers and acrylic cool monomers have a certain volatility and are irritating to the skin. During initial contact, direct contact without proper protection or long-term exposure to high-concentration environments may cause skin allergies, such as Red and swollen eyes, rashes on the body, itching, etc. But after getting used to it for a period of time, it will no longer cause allergies, skin rashes, etc.

Skin irritation:
Maintain good ventilation
Operators must wear protective clothing, glasses, masks, gloves or finger cots, etc.
Pay attention to washing hands frequently and changing clothes and gloves frequently.
Once glue comes into contact with skin or any other part of the body, rinse immediately with plenty of water and soapy water.
