Can UV adhesives cure under visible light?

Of course, you can, mainly curing under ultraviolet light. It's just that the ultraviolet rays are a little weaker than the ultraviolet light of the UV lamp in the sun, so the curing is a little slower.

It depends on your glue, UV glue has wide-wave curing and short-wave curing; That is, it is light-sensitive and insensitive, if it is light-sensitive, it can be solidified, if it is not, it can't.

It is recommended to buy a suggested UV equipment to do, and it is not expensive, and it is about 500 yuan for one (I also sell UV lights, hehe).

Most of them can be as fast as UV light, and generally UV adhesives need to be stored in the dark.

No, because the UV board is not glass that can transmit light, it has to be dried before it can be cured.

Summary. Hello dear, no. UV adhesive is equivalent to other adhesives, and its odor, volatile and toxic components are minimal in the liquid state when it is not cured.

After all, it is made of chemical ingredients, so the workplace should maintain the relative flow of air, and the average worker working in this environment for a long time should take protective measures according to safety production regulations, such as wearing work clothes, masks, gloves or finger covers. 3. Do not directly contact UV glue, even if there are some UV glue that claims not to hurt your hands, do not go to contact with your hands for a long time, if you accidentally come into contact with UV glue, you should immediately rinse with a large amount of water, soap and detergent.

3. Do not directly contact UV glue, even if there are some UV glue that claims not to hurt your hands, do not go to contact with your hands for a long time, such as skin excitators accidentally contact UV glue, should be immediately rinsed with a large amount of water, soap, washing leakage.

Don't just dismiss it.

Can't you do it?

It's better not to.

You don't have to touch with protective gear.

UV curing adhesive can not be completely cured, can secondary light solve it?

Hello, dear information verification. UV curing adhesive can not be completely cured, secondary light can be solved, pro. 1. Replace the UV lamp with high ultraviolet light intensity, which can be cured twice, and there is no problem at all; 2. If the double-curing glue is double-cured, the ultraviolet rays will be heated and cured after irradiation; 3. Add a certain amount of UV glue curing accelerator or replace UV glue; 4. Pay attention to the rational use of thinners.

The reasons for the incomplete curing of UV glue are: 1. The wavelength of UV lamp does not match the wavelength of UV glue; The amount of UV lamps can be the first in the world; When the ultraviolet lamp is used, the search room is too long, and the ultraviolet light is weakened, resulting in insufficient energy of the light source; 2. UV curing glue is a double-curing glue, and ultraviolet irradiation cannot be completely cured; 3. The storage time of UV curing adhesive is too long; 4. Add an excessive amount of diluent that does not participate in the reaction. Thank you for your consultation and have a great day.

Good evening, UV glue cures after ultraviolet irradiation cures to form an acrylic-like polyacrylate structure, which can be soaked in strong solvents such as methylene chloride, chloroform or xylene for a period of time and then re-swollen and dissolved, if it is UV polyurethane or UV epoxy after cross-linking to form an insoluble and non-meltable three-dimensional structure, it can generally no longer be dissolved in organic solvents.

Of course, it cannot be cured without UV light. It can't be used.

UV-curable UV adhesiveUV technology, referred to as UV technology, is considered to be an environmentally friendly green technology, also known as 3E technology, that is, energy saving, environmental protection, and economy.

Main applications:In coatings, inks, adhesives and other fields. It is mainly used in coatings, inks, adhesives and other fields. Among them, ultraviolet curing UV adhesive is widely used in glass products and jewelry, glass furniture, medical appliances, electronics, electrical appliances, optoelectronics, optical instruments, manufacturing and other fields, such as electronic circuit boards, electronic components, digital cameras, electronic scale manufacturing, buzzer sheets and other products.

What is UV? UV is the abbreviation of ultraviolet ultraviolet ray, which is the wavelength of 200-450nm, of which the UVA wavelength is 320-390mm, the UVB wavelength is 280-320nm, the UVC wavelength is below 280nm, and the UVV wavelength is above 390nm.

Of course, it cannot be cured without UV light.

Sunlight also produces ultraviolet rays, but the wave intensity is not strong enough, and you can leave it under the sun for a long time to see if there is any change.

What exactly is your UV glue used for.

UV glue requires ultraviolet light to cure. Ultraviolet rays are usually found in sunlight or during the day. It's just that the intensity of UV ultraviolet rays is different.

WKM-1A curing UV glue.

Yes, but it takes a long time and the curing effect is not as good as it requires. All need UV light source irradiation curing, now the rapid curing equipment is generally UVLED light source, UVLED light source high efficiency, small heating, no pollution, power saving, long life of more than 25,000 hours.

Curing speed 3-5s - Walkom.

UV glue needs UV light fixing lamp to cure, in the case of no curing lamp, it can be irradiated under strong sunlight, sunlight irradiation takes a long time, it is likely that the curing is not complete, and the effect of shadowless and traceless will be relatively poor;

For example, it is good to irradiate it under a 1000W UV lamp for 5 seconds.

Ultraviolet light is required to cure.

Summary. Hello! Dear, very high for you to answer, your consulting teacher to help you inquire about the following UV glue how to cure quickly:

1. One of the two objects to be bonded is transparent and the surface is clean and dry and grease-free 2. Apply UV shadowless adhesive on one of the surfaces, close the two planes, and use a suitable wavelength, usually 365nm 400nm, and the energy of the ultraviolet lamp or illumination with high-pressure mercury lamp for irradiation, the light should be from the midpoint to the periphery, and confirm that the light can indeed penetrate to the adhesive part 3, it is recommended to illuminate about 6s, and when the initial positioning, remove the remaining glue on the workpiece and then re-illuminate to complete curing.

4. The curing time should be different according to different preparation materials, glue thickness and ultraviolet intensity. It is recommended that users purchase ultraviolet intensity testers and test light intensity before bonding to reduce the rejection rate 5. The temperature also has a little impact on the activity of the glue, and the curing time should be appropriately extended when the temperature is low 6.

7. When bonding plastics, the content of ultraviolet absorbers in plastics should be considered, and the high content will seriously affect the transmittance of ultraviolet rays, which will also have a significant impact on the curing efficiency of glue, and even lead to the failure of glue to cure 8. It is recommended to use low-viscosity products when bonding in large areas. If the conditions are available, it is recommended to purchase vacuum equipment and laminate it in a vacuum environment to remove air bubbles and improve the yield rate.
