Hello, do you know what is the minimal temperature of using, humidity, hardening time and life time? Regards
Good morning, Tef Gel never dries and never cures. There is no curing time and the lifetime will be certainly >50yeras. The air humidity is not relevant for application of Tef Gel, same as the temperature. Temperaturelimit for Tef Gel is 230°C, above it starts to brun.

Good Morning, I was hoping to purchase a tube of Tef-Gel (Item no. 61152) with some other items but have been advised that you do not currently ship it to Ireland. Do you have a similar product that prevents corrosion between stainless steel fixings and aluminium that you do ship to Ireland. If you do can you please advise on what it is?. Many thanks, Joeph Gilmartin
Joseph, Tef-Gel is the best product for stopping corrosion between dissimilar metals. It does not dry out like the old Durolac. I have used it for 12 years with the first 6 years running a large aluminium motor yacht. I gather SVB can't supply Tef-Gel to Ireland due to some licencing arrangement. So there must be a distributor in Ireland. I would try to source it locally. It is expensive but a small bit goes a long way.
Why this product is not available?
Dear Carl-Erik, when we haven´t any products in stock, they are not available. The reason ist most of the time supply difficulties. Your SVB-team.
