a little glue testing

<< < (4/5) > >>

simk:
First glueup is done, maple, ash, yew, oak, looking good. Bending it tomorrow. Next one will be a bit more of a challenge for my ordinary wood glue: higher drawweight, tropical hardwoods and bamboo. Stay tuned, I will report 🤗

Chumash:
For tropical hardwood I had used "Bindan Cin" a resorcinol glue like urac.  It is a D4, but two components glue: a white powder and a dark red resin.
In my opinion the best glue for gluing wood to wood (gap filling and a long open time (90 min), heat resistant after hardening up to 170°C, recommended for oily tropical woods and it has seawater resistant gluelines).
May be not available in Switzerland?

simk:
Thanks Chumash, I read about this type of glue. Seems it has come a little out of fashion, but a good one for sure. Think its still available and recommended in tbb4 for laminating. Also read it leaves dark gluelines too...maybe an interestig accent. 😇
Actually I'm not looking for the best glue but only for a good enough and easy to use, non toxic 🤗
Just experimenting 🤗

Chumash:
Bindan Cin has the colour of the left lamination, may be a little darker.
For sure, it is available but I don't know the import regulations of swizerland - the white powder contains Formaldehyde.

If non-toxic is important then none of the urea glues (unibond, urac, others) are good for you. They all contain formaldehyde and are in the same class as epoxy in terms of not wanting to breathe the fumes.
