Resin and vescocity

[All-Clear]

I'm still trying to understand what is meant when people talk about the vescosity in resin. Is the vescosity number in resin different for winter months than summer months? Can you use one resin with a certain vescocity level all year long? If someone can explain it to me a little better so I can understand more clearly and how vescocity works in relation to resins I'd appreciate it. Also, I have the resin from Delta Kits. Is this resin good for summer months hitting 100 degrees because that is the weather hitting Central California in the next couple of weeks, thanks

Avoiding the scientific explanation, viscosity is how well a liquid will flow e.g. water ( low viscosity ) compared to treacle ( high viscosity ). Most resins supplied by reputable manufacturers operate all year round with no problems. What is important is that the temperature of the glass being repaired is within a recommended range so that the resin achieves good penetration of the damaged area and avoids problems with expansion/contraction of the glass, ideally between 10-25 deg. cent. ( 50-77 deg. far. ) Keeping your resin stored at room temperature and not exposed to daylight will ensure the resin will operate correctly.

Viscosity is how thick the resin is.
Honey has a high viscosity.
Water has a low viscosity.
Viscosity of a liquid can vary according to temperature.
In a cold temperature, a low viscosity resin might flow into a crack better than a high viscosity resin.
In California, if the resin you are currently using is working well for you, you should not have to change viscosities, as we have a mild climate.
I would be wary of working on a hot windshield, since hot windshields can crack out while you are attempting a repair.
Take the necessary steps to cool the glass before doing the repair.

Thanks Glasseye and Mr. Bill. Your information was very informative. Now I have a better understanding of resin and how it works, thanks again.
