What is the fire rating of gorilla wood glue?

[Gary111]

I have tried to find online but can't see it.
It's the foaming sort that expandsthat I want to use.

Does anyone know please?

I'm curious as to why it makes a difference

Won’t the fire rating of the wood be more of a concern?

Maybe, but worth bearing in mind that most conventional wood glues break down at 70 to 80 deg. Centigrade (and that PVA is flamable, whereas Gorilla Glue - a PU glue - is not according to the technical sheets)

It's a rental property so I have to be careful about the fire rating of anything in there, according to the risk assessment.

is that in use as in no flamable vapours but when set can burn ??
i feel an experiment will pu set lump off honycomb and a ronson happening tomorrow

well the everbuild foming pu glue as you expect has gone solid [non expanded]over the last 2 years off no use so cut off a strip 2 postage stamps in length and perhaps 0.5-0.8mm thick with a normal candle sized flame from a lighter and the acrid smoke whilst under the flame suggests it would not be classified as self extinguishing without flame but off course may perform different if foamed but doubt it ???

Think about it, though - many fully rated fire doors and fire door casings are flamable because they are made from timber. Surely the significance is in the type and quantity of material and the speed at which it combusts? A 1 hour flush fire door set typically comprises a chipboard core door blank with plywood facings and hardwood lippings, hung in an appropriate hardwood or softwood casing, with appropriate gapping, intumescent strips, fire stopping in gaps around the outside of the casing, etc. It will all still still burn, albeit at a controlled rate. It might help if the OP could give us the context of the query so that a more appropriats answer can be given

I'm thinking the Gorrilla Woodworking Glue is just a yellow-ish PVA (it possibly has some water resistance). It looks and works just like any other white / yellow woodworking glue. (maybe starts to grip a little too early for my liking) But just a normal PVA

Gorrilas other glue, the fully waterproff one, the PU, the stuff that foams (that causes your skin to go black and won't wash off) is a very very different type of glue,

I have to admit the only type of Gorilla Glue I have used, and not very often at that because it is ridiculously expensive whilst being no better than many other brands, is the PU variety. D3 PVA I buy in 1 gallon containers and I call it PVA.

Either way the manufacturer's MSDS sheets should supply the necessary information, but other than specialise industrial adhesives I can't think of any standard wood glue which is classed, or needs to be classed as, fire resistant - especially given that glue joints should be a few microns thick.

It would help if the OP could tell us why he needs to know this, though, especially given that individuals can no longer make up their own "fire rated" doors, casings and linings, etc because home-made items simply cannot meet current fire regulations
