Sikaflex 512 application at low temperatures

[UFO]

I am finally getting around to fitting solar panels after delays due to too much work and then a bad back for the last month. I have got all the bits so I am ready to go. BUT it is now getting cold and reading the Sikaflex 512 datasheet it says 'Application temperature 5°C to 35ºC'. Anyone got any experience of using Sikaflex at low temperatures? I suspect, looking at the graph, that it will just take longer to cure. Although even at 10°C 3mm thickness takes 4 days according to the graph.

I'd be very careful if it's less than 5 degrees, it's maybe too low for the reaction to take place at all.

I think it cures by moisture from the air reacting with the mastic gel. If it's anywhere near freezing the reaction will not take place at all. Concrete works like this too. There is a cut off temp below which you don't get any gain in strength.

Thank you for this idea. I was thinking about how to do this but a friend has now said I can park up in their industrial unit, once they have space - they install seasonal lighting / displays in shopping centres and the like. I'll still need to watch the temperature but there will be more opportunities with it being indoors.

I have a single 140W panel and I will use 6 aluminium angle brackets

how much shipping and import duties did you pay, i just bought some clothes from the states, £320, weighing 10lb, shipping was £65, the duty was £98, not so cheap at all.
