I've got one of these that I used to glue part of the valve gear bracket to the footplate on an old mainline Royal Scot that I restored. The plastic was rather soft and "soapy" and the u/v glue worked very well. I was put onto this by a friend in the US who got some to help her stick difficult joints in dolls house furniture and the like. She had a more expensive version where the u/v torch comes in a metal box, (around £20 here) but I suspect the cheap pen version is just as effective. Revell have started doing these as well, theirs comes as 2 "pen types" for about £10.

In the infrared light risk assessment for your workplace (for eyes and skin), your distance from the source of radiation and the amount of time spent in front of the radiation source are also relevant in determining the strength of your IR radiation exposure.

All filters of the infrared safety spectacles and of other PPE in this range must meet the transmission requirements of EN 171 and are divided into defined levels of protection accordingly. Standard 166 for general personal eye protection stipulates further requirements for infrared safety spectacles. You can find illustrations and other explanations of these specifications and the applicable standards for safety spectacles on our website.

When it comes to the long-term dangers posed by infrared radiation, the key question is how to provide employees with effective, reliable protection to keep them healthy while they work.

I'm surprised no one has suggested using printer resin and a UV LED, but do take appropriate eye precautions when working with UV.

If you operate in areas with particularly high levels of infrared radiation – right in front of the iron-melting furnace, for instance – heat protection clothing and special heat protection are indispensable.

Got mine here, £2.69 inc. postage, don't know how much there is in each pen, but mine is still going strong. Suspect it's use is for very tricky specialised joints.

Whether you work right in front of a furnace in a foundry or a certain distance away, appropriate eye and face protection – plus where necessary the right heat protection clothing – are essential for you to be able to work safely.

Oh yes, that's absolutely possible. Use a syringe (without needle) pull up some resin and you can use it like the pen. Here you have the advantage of free choyce of color. But I think, for this price I will use better the pen.

Handy as a simple pen, but would not be surprised to see liquid on sale and then just using an LED to set it. No need to buy new pens.

There is one big advantage to Super Glues: You have all time you need to put the parts in position. The glue does not activate before you light it with the UV lamp. So be carefull working in sun light

The pen holds glue 'cartridges', so refills are available. They are black plastic and have a cap, so shelf life is much better than superglue.

Our infrared safety spectacles feature our proven uvex supravision coating technology to pair top protection with a superbly clear view! Choose from the sporty uvex pheos cx2 and the uvex super f OTG as overspecs for prescription spectacle wearers. Experience the quality of our infrared spectacles for yourself and try out the colour recognition on our uvex IR-ex page!

Our infrared light spectacles also meet the requirements of U.S. standard ANSI/ISEA Z87.1 and Japanese standard JIS T8141. This multi-certification allows our infrared spectacles to be used for protection when welding and from solar radiation as well. Conversely, a pair of welding safety spectacles does not provide sufficient protection against infrared!

This glue works on the same principle as the UV resin printer. The material is transparent and stay transparent after hardening. The front end of the stick is a small needle dispenser like on the Revell glue. You squeeze the soft tube and it is possible to use it really precisely. On the other end, there is a UV LED lamp to harden the bond.

Depending on its intensity, proximity and the duration of exposure, infrared radiation can be harmful to the eyes as well as to the skin. The eyes generally react much sooner and are much more sensitive than the skin to the effects of IR radiation, which can be harmful from a certain degree of intensity and exposure. The heat can in fact be beneficial to skin to a certain extent: infrared heat in the form of infrared lamps is used for medical purposes such as treating pain, circulation problems, stiff joints, inflammation etc. However, excessive heat can also cause heat cramps, heat exhaustion, heatstroke and burns.

looks useful. this one seems to be on ebay for the UK, but there are others available from China. Suspect we will see a lot more of these. Keeping the nozzle clear might be the tricky part.

They promise 5 seconds lighting to harden the glue. I better light 10 or 20 seconds. Better to long than to short. If you are printing resin, you can use your UV box.

Infrared radiation, or thermal radiation, was discovered in the year 1800 by Friedrich Wilhelm (William) Herschel, musician and astronomer. Everyday sources of infrared radiation include:

For workplaces where less-intense heat sources do not pose an immediate threat but lasting exposure to infrared poses a hazard, uvex has developed a special range of safety spectacles to provide protection from IR radiation: uvex IR-ex. Combining safety with a clear view, these safety spectacles have the following impressive properties:

In professional settings, employees working in glass production and the processing of metals or plastics are among those exposed to the potentially harmful effects of infrared radiation, which is invisible to the naked eye. This article will set out the dangers posed by infrared, list the areas in which IR radiation is found and provide clarification on effective measures to tackle the problem.

First of all, welding spectacles and infrared safety spectacles are subject to two different safety standards: while welding spectacles are designed specifically for welding applications and the respective output from the welding machine in accordance with EN 169, infrared safety spectacles are designed in accordance with EN 171; this standard intends for the eye protection to be selected according to the average temperature of the radiating heat source.

I'm surprised no one has suggested using printer resin and a UV LED, but do take appropriate eye precautions when working with UV.

Particular caution is advised in the event of infrared coming into excessively long direct contact with the eyes because its harmful effect on eye health varies depending on how deeply the IR radiation manages to penetrate the eye tissue:

Infrared is radiation with a wavelength between 780 nanometres and one millimetre on the electromagnetic spectrum. This IR radiation cannot be perceived by the naked eye, even if the heat emitted by the radiation can be felt. Particular caution is therefore required when dealing with extremely warm and prolonged radiation. Infrared light is divided into three types depending on the wavelength: IR-A, IR-B and IR-C. The longer the waves of the IR radiation, the less able they are to penetrate fabric or dermal layers. At 780 nm to 1,400 nm, the comparatively short-wave IR-A radiation is therefore the most harmful type in terms of human health (greatest degree of penetration). UV light is also invisible, but its wavelength spectrum is below 400 nm and it therefore has a shorter wavelength than radiation within the visible range of the spectrum.

I have used it for fitting runs of point rodding, setting each point separately. I have used it for fixing glazing material inside coaches and brake vans. I have also added it on top of the glazing material to fill deeply recessed windows to make them flush glazed.

Assuming it keeps, this looks handy for the toolbox for any items which you want to position carefully but don't want to hold for several minutes & if kept sealed, it should not harden around the application nozzle either.

A pair of uvex IR-ex spectacles can provide you with optimum protection against the effects of infrared in your workplace. To determine which spectacles have the correct level of protection, establish the average temperature of the source of radiation – i.e. the burning object (such radiation measurements are performed as part of the workplace risk assessment in larger companies). The table provided sets out the official levels of protection of the relevant EN 171 standard and the level of protection that uvex infrared spectacles offer:

As well as the acute risks posed by overheating, the chronic effects of infrared light on the eyes (damage to lenses and retina) are good reason to wear appropriate personal protective equipment when working with infrared radiation.

UV Gluekit

I have been using a similar one for a while now. Useful for many things because it allows as long as required to position correctly, but goes solid rapidly when lit up. It is also very clear.

On resin it works better than super glue. PVC to resin or PLA to resin works good aswell. I would suggest to file the surface of PVC or PLA to make it a bit rough. Then you get the same adhesion power as super glue. The connection material is resin, so it is brittle after exposure to UV, means elasticity is zero.

Aside from the aforementioned situations in people’s personal lives, there are many industrial settings in which infrared radiation is used in a variety of ways. Typical examples include:

Comparing the two standards and the protective effect mentioned therein of welding safety spectacles and infrared safety spectacles, it quickly becomes clear that IR spectacles are capable of absorbing five to ten times more radiation within the 700 to 2,700 nm spectrum than welding spectacles – while still allowing just as much visual radiation through. Our professional uvex IR-ex infrared safety spectacles therefore provide effective protection when working with both types of radiation, meet both standards (EN 169 and EN 171) and are way ahead of welding spectacles when it comes to the protection that they offer. And, because our IR-ex spectacles also provide protection from UV radiation up to 400 nanometres, the requirements of EN 170 for UV filters are also met. Our IR-ex tint therefore offers multiple types of protection for virtually all hazards posed by optical radiation. This multi-certification allows our infrared spectacles to be used for protection when welding and from solar radiation as well. Conversely, a pair of welding safety spectacles does not provide sufficient protection against infrared!
