Re: LOL Merry Christmas
Jeff..I notice in your catalog that you have a thermal thermomater and at what temp is the best for a repair, I also noticed this piece of equipment on another site so there must be something to it, so that you use only one resin. whats the low end and the high end with your resins, thanks for the reply.

Delta kits
Sprinter,
We just put a thermometer in our catalog, due to "popular demand." We had been getting requests for a while for one, but we couldn't find a quality one for a low price, until recently. As far as the best temperature, there are many others here that know better than I, but when i'm doing them I like to have the temp between 80-100 degrees.
Anyone else like the temp different than that?

Re: Delta kits
Hello Sprinter,
I use a handheld Raytek MT4 infrared with laser point. As far as the temp. I try to due most standard repairs at between 70-75 deg. I feel that this temp. range provides a more stable glass environment for most standard repairs. Although there are times when you may want reach into your trick bag and use heat to make the glass a little warmer. Each situation/repair will dictate what needs to be done. This is what i find works best for me.
Jeff, i wish you would have had that when i bought mine.
Merry Christmas
Pay it foward,

Re: Delta kits
I have been doing some research on infrared thermometers. I have inquired about La Crosse and Raytek models, and none of them claim to be effective at measuring the temperature of glass. Here is one of the disclaimers (for the La Crosse model):
------------------------------------------------------------
The IR-101 provides easy, contact-free temperature measurement:
*For hard-to-reach and inaccessible locations
*On and inside buildings (heating and cooling loss, cold spots in a house)
*For foodstuffs (no transfer of germs or opening of packaging)
*On hot components (engines and other machinery, motorsports, model construction)
*For heating and sanitation applications (e.g., heat lost)
*For engineering (how hot is your CPU cooler getting?)
*For cooking (is the griddle, waffle iron or pizza stone up to temperature yet?)
Note: The IR-101 is preset for an emission factor of 0.95. Most surfaces have an emission factor of 0.8 to 0.98 (the darker and less reflective the surface, the greater the emission factor). Please be aware that infrared thermometers are not suitable for measuring the temperature of polished metals, which have a very low emission factor. Affixing adhesive tape to polished metals, or painting them, increases the emission factor and reduces the inaccuracy of the measurement. Also, infrared thermometers cannot be used to measure the temperature of transparent objects or air temperature.
------------------------------------------------------------
It's this last statement in particular that has me worried that infrared thermometers are not appropriate for the measurement of glass temperature. Even the Raytek models with adjustable emission sensitivity do not claim to be able to accurately measure the temperature of glass.
Are we all sure that infrared thermometers are the way to go? What are the alternatives?

Infrared Thermometers
Saammy,
Personally I don't use a thermometer. When I do a repair, I just feel the glass.
With IR thermometers though, they are saying simply that their measurements could be off. With windshield repair, an approximate temperature is perfectly fine.

Sammy,
I am not familiar with the Lacrosse thermometers that you talk about but I am familiar with the Raytek MT4. You are partially correct in that Raytek claims not to be able to take a surface measurement through glass. It will read the surface temp of glass though. Something to keep in mind here is the margin of error. I feel few degrees here or there is not that critical. Remember we are using UV curable resins, not resins that need to cure under a specific temp. range. If you are using a good quality resin, and are technically sound your repairs will be fine. So as long as the unit will read the surface temp of glass I am sure you will be in the ball park.
As far as alternatives, well in the aviation industry we use in specific situations a Temp. indicator. This is an adhesive strip with temp. sensitive dots. Each dot has a temp range. These dots darken with increasing temps. The hotter it gets the darker the dots get. This probably would not be effective for our purposes but they might make something that would be in a similar format. I don't know of any though.
Safety is and always will be first priority but common sense must be factored in. So for know I will stick with my Raytek. I hope this helps your decision process.
Pay it foward,
Brian

Re: Delta kits
Jeff - How do you determine if a windshield is too hot or cold by hand? Do you just check to see if the windshield is too hot to touch? Also, have you gotten any positive or negative feedback from technicians that have used the La Crosse thermometer out in the field?
Brain - The strips you mention sound similar to the strips used for home aquariums. But you are right, I'm not sure how effective or practical these types of thermometers would be in a windshield repair setting.
Thanks for the feedback guys!

Re: Delta kits
the problem with too hot of a shield is you run the risk of injecting the resin under the glass and leaving a circle around the repair thats very noticable, I forget the term used, as long as the shield is touchable by hand, that is that you can rest your hand on it with out getting burned then it's cool enough for a repair. however some resins from some manufacturers might recomend that the shield be in the range of 40-90 degrees, their covering themselves for the above circle in hot wheather. if a thermometer would help the repair person and this is new technology then I'm all for it, it could also be a way to train new wsr people so that they don't think on their own and the repair is smooth and as perfect as could be.
I'm in arizona so even though it might be in the shade it's still a 110 out side best to be safe than sorry.

Re: Delta kits
There are two reasons temperature is important with respect to windshield repairs. 1) the glass temperature effects how well the resin will "wet" or fill in the pores of the glass. The more contact surface between the resin and the glass the more adhesion and resulting strength. Note that the old method of using very thick resins to fill cracks is now preceeded by using a thinner resin to "wet" the break fro superior adhesion. 2) the temperature of the resin (which can be altered by contact with the glass) is important as well. If the resin goes over a specific temperature, it begins to change or even breakdown. This is much like the way motor oil changes when over heated. This threashold varies from resin to resin but can be as low 105 degress. Add to this that resin that is too warm tends to "flower" the break as noted above. Thats when the resin flows beyond the repair area and into undamaged laminate. Resin that is too cold can thicken and become difficult to fill tight breaks.
