Re: [A/S] I haven't been able to find Vulkem 921

Thanks Camilla and all who responded.

Here is what VTS had to say:
Trempro 636 was the modern name for the legendary Airstream sealant known by many as Vulkem. The formulation remained substantially unchanged for decades.

In early 2011, Tremco discontinued Trempro 636 because more technologically advanced no-VOC silylated polyurethanes like Trempro 635 are now known to surpass the performance of the old polyurethanes in transportation applications in every meaningful way.

I guess I'll be ordering Tempro 635.

Thanks to all,
Paul
