Wood glue for outdoor garden gate nerd level
I am looking for links to tests of outdoor glue. I need to glue a garden gate together. A dowel of 7x1x5 cm should fit into a hole with a fairly precisely chiseled mortise.
When I removed the rotten "board" that I now need to replace, I noticed how damp the wood was. In the vertical wood of pressure-treated pine from which the hole was cut, the gate lock will later be mounted. This means it will be subjected to a lot of vibrations when it is slammed shut. The wood is located outdoors in a brutally sunny southern position with the wind constantly present. It will be painted Falu red, which makes it quite warm in the summer heat. Therefore, I want to use the ultimate glue product for this purpose. I happen to already have a tube of byggmax.se "construction adhesive." But I hesitate to use this because it may be too thick to be squeezed into all the spaces in the hole when the dowel goes in. Furthermore, I have very little data on this anonymous glue. I assume it is strong enough, but can it adapt to the wood's movements and moisture variations? Perhaps it is too stiff and brittle. I have, of course, considered PU glue like Cascol Wood Glue Outdoor 3337, but I am also somewhat skeptical here due to the brutal temperature and moisture fluctuations and vibration impact. I read somewhere that it is not approved as a construction adhesive (don't know why or if that is correct). If I am to go with PU glue, is Casco the best choice? I have the impression they are the largest on the market, but there is also danlim outdoor and others. Is there any independent test for glues in the same class? Is "Water-resistant and meets the requirements of EN 204/205 class D" sufficient? What exactly does this class mean? What is the difference between CASCOL 3337 and construction adhesive?
If one pre-paints with impregnation oil, does it affect the adhesive's bonding ability? This "oil" is very diluted with solvent and penetrates quickly and dries quickly. Many questions that probably interest several people.

For this project, regular outdoor white glue works fine if the hole is tight. If there's a bit of a gap, it's better to use PU glue that foams a bit and is gap-filling. If the wood is damp, PU is more suitable as it cures with the help of moisture. Both types of glue will provide a joint stronger than the wood around it. Both types of glue can withstand temperatures and moisture, but PU glue usually has a higher rating for outdoor use (D4).
If you want a genuine wood glue for construction purposes, you should look at resorcinol-phenol glue like Cascosinol. These are used by the industry and are a bit harder to get as a consumer. Theofils has it, among others:

This is the best glue you can buy, but as mentioned, regular white glue or PU glue also works.
Glue everything before oiling.
