Default What type of adhesive is "No More Nails"?

I am in the UK and would like to ask some questions about glues.

QUESTION ONE
Does anyone know what category or type of adhesive is Unibond's NO
MORE NAILS sold for general purpose home use?
See http://www.dm-tools.co.uk/images/UNINMNC.jpg
Does anyone have an ingredients list for this adhesive?

QUESTION TWO
Is NO MORE NAILS stronger for woodwork jobs than that white or yellow
runny woodworking adhesive which I believe is some sort of PVA
adhesive that dries off to leave a hard resin.

QUESTION THREE
Does NO MORE NAILS form a stronger bond to the materials being glued
than Araldite? Can NO MORE NAILS be heated to a greater temp than
Araldite (which I believe weakens at 70 C)?


Gripfill, No More Nails etc are (apparently) block copolymers
http://en.wikipedia.org/wiki/Copolymer#Block_Copolymers

I suspect normal woodworking PVA gives a stronger overall bond because it
penetrates the wood grain to a certain extent before polymerising, so the
bond has more "depth". NMN just glues the surfaces.

Polyurethane glue may be even better in a clamped joint as it expands and
gets forced into the grain before curing.
