This is why I love Airforums. I thought that Vulkem was Trempro 635. Now I know that Vulkem is Trempro 626. Thanks for the info!

I have asked a few members this but in case they are not able to provide input I thought I'd put this up publicly.

I was curious:

1.) Do you know if Vulkem had a number assigned to it (i.e. Vulkem 116 etc)?

2.) I was told that DyMonic 100 was the new product recently by a authorized Airstream dealer - has anyone also heard this?

3.) I see Sikaflex 221 is on the AS website - it this any good?

4.) Does anyone have any familiarity with ParBond or Acryl-R....are they good for certain applications?

Airstream used to recommend Sikaflex 221 and Acryl-R for sealants for different applications. You may find specific recommendations in current owner's manuals (they can be accessed online) or contact consumer relations at Airstream and ask them. Vulkem was used long ago and may have been superseded by newer sealants.

The Airstream is sold; a 2016 Nash 24M replaced it.

Dymonic 100 sets a little faster. 2 hour skin, sets in 5-6 hours. Good if you are working in dusty conditions.
