Urea Formaldehyde
HoBow:
That text calls it modified UF.
Pat B:
A past member of PA from Italy, Alby, used Weldwood Plastic Resin in his lam bows with good results...and Alby made some fine lam bows and self bows. 8) He could not get Urac in Italy but he could get Weldwood P R. I used it on a few backed bow with good results. No failures.
It comes as a fine brown powder in a 1# tub(about $5.00) and you just add water and mix. I found it to be very similar to Urac.
Mohammad Javad Shoaee:
Thank you all.
problem is that i can't find or buy Urac or Weldwood here.i want to use raw urea formaldeyde which is a white powder.
i've found some formula on the net for adding flour as extender,limestone powder as filler and ammonium chloride as hardener and it'll have one hour pot life?
is it posible?
any advices are welcome?
Pat B:
I've never made glue except for pitch glue that I use to haft arrow heads and blades, not bows. In the Traditional Bowyers Bible Vol I there is a chapter on glues. Might be info there about concocting glues but there is a strength test you could try with your mixtures and see which is strongest or if it is viable for what you need. Casine glues, modern carpenters glues and animal glues are all used and very effective in bow making.
shikari:
Where are you located Mohammed?I am sure there are local materials available that will make the glue you need for your purpose.
