What is UV Glue?
Ultraviolet glue uses a photochemical component, an ultraviolet light, for curing. UV consists of electromagnetic radiation in wavelength ranges of 10 to 400 nm (750 THz). That’s shorter than visible light, but longer than X-rays. In that way, this glue is a polymer which relies on ultraviolet lighting for cross-linking and creating a durable and solid foundation at a molecular level.
This contrasts other adhesives. Those adhesives typically rely on drying, a process that requires high temperatures or takes long periods of times. But with a UV solution, adhesive components overcome any needed activation energy needed for cross-linking and photon particles.
How Does UV Glue Work?
Ultraviolet adhesives come in varying packaging. Most are epoxy based. Acrylates are popular products too. You also have access to multi-component solutions with photochemical promoters. These degrade into free radicals after UV light exposure. The radicals significantly increase speed rates of UV glue curing.
UV curing is in heavy use in large scale industries where products like cosmetics, food, autos and medicine are manufactured. The chemistry behind UV adhesives is also utilized in the production of UV curable inks.
Thanks to its relatively quick process as well as the absence of solvents, UV curing is deemed an adaptable solution if you want a highly flexible, fast production.
Fields of Ultraviolet Light Curing
UV light adhesives are incredibly versatile. It’s used to join different materials, but as a safeguard, filling and reconstructive solution. Should you need to join two uneven surfaces, you have the facility to level out the unevenness by applying the adhesive densely without filling gaps.
Applied in layers, an ultraviolet light curing product has a one centimeter gap filling effect. It can be applied to reconstruct a range of materials. This is especially suitable when sheathing low current cables or to replace small object fragments.
This solution is exceptional for:
- Plastics, especially transparents
Repairs of All Kinds With UV Light Adhesives
A UV glue enables stabilization of adhesive joints. It is also suited for repair and as a filling material. As UV light isn’t not aggressive like other adhesives, it’s exceptional for sensitive materials. Further, UV glue contains no solvents. The solution’s suitable for modeling.
Small surface damage is easily corrected with UV adhesive. Apply the adhesive to cracks. It’s transparent and feels like hard plastic after curing. You’ll find once the project’s complete, the repair is near invisible. It’s also a practical solution for repair areas that need high levels of vibration.
Repairing Floor Coverings
Floor covering damage is infrequent but it happens. Especially in households with children or pets. Broken glass and claw markets make your floors less attractive. There is an alternative to replacing sections of floor or tearing it out entirely. Try repairing the damage with a UV glue. Fill the scratch or crack with the solution and cure it with the UV lamp. To level the application, sand the dried adhesive.
Sealing Drill Holes
When drilling holes are unavoidable, you can use UV light to correct this matter efficiently. UV light will eliminate issues of color tone. This is always a difficulty.
Adhesive UV lighting is the ideal solution here. It comes in practical tubes for precision application. The pot life is freely selected. This means the area’s easily repaired with no fuss or muss. After hardening, the surface is ready for filing, polishing or grinding. The project’s completed in no time.
One difficult fix is glass bonding. It’s a challenge because the material is a sensitive surface and highly susceptible to more damage. A majority of adhesives aren’t engineered to work with these properties. Gluing glass to glass is a tricky endeavor, but keeping glass in place with most materials can be a problem for the DIY-er.
Bonding two unique surfaces is a further problem, especially while waiting for the solution to dry. While waiting for this, you’re responsible for holding components together. They can slip. This is a common problem with glass, which can also break or splinter under stress.
UV adhesives lets you control the curing process. You’ll never worry about slipping because there’s no waiting period. Another advantage is glass’s transparency. It can be exposed to UV light on either side, front or back. This ensures the adhesive is fully developed and bonded. That makes ultraviolet light perfect for glass.
UV Adhesive Tutorial: Repairing a Surface
Here are the steps for most UV adhesives.
- Thoroughly clean surface to be bonded. It has to be free of dust and grease. The surface should be completely dry as well. Use a lint-free cloth and pure alcohol. Smooth surfaces may need roughening so that the adhesive develops optimal potency.
- Apply the adhesive. You can use several layers to fill holes and grooves.
- For better bonding, prepare the surface with a thin layer of adhesive. After drying, apply a denser layer to optimize glue properties.
- Bond surfaces and use the ultraviolet light to cure the adhesive.
- If light isn’t reaching everywhere, press components together firmly for thirty seconds.
- After curing, process the adhesive mechanically, such as grinding.
- The surface can now be painted or varnished.
Storage of UV Light Glues
To manage the durability of the product, keep it stored in a cool, dry place while it’s still sealed. Keep storage temps between 5°–25° Celsius. Open containers are best stored airtight in the refrigerator. Remaining contents should be used immediately.
Instructions for Safe Process of UV Curing Adhesives
In order to safely work with UV adhesives, use proper safety precautions. You want to protect the workplace and the user. These products are capable of prompting allergic reactions, impacting the respiratory tract, and irritating skin and eyes.
Wear gloves and goggles when using these applications. Always work in well-ventilated areas. If this isn’t possible, wear a respiratory mask. If the adhesive comes in contact with eyes or mucous membranes, get medical attention immediately.
With proper safety measures, a UV adhesive is highly versatile and worth the higher price. It’s becoming the resource for a variety and industries and for DIY-ers.
