Super glue
MDF comes in different grades including fire rating (FR). You will need to speak to your supplier as to which one. Remember though that you will likly need to make sure whatever you use with it (paint, laminate coverings) are FR too.
Medium Density Fibreboard (MDF) is composed of hardwood and softwood residuals that have been broken down into fibres. They are then compressed using temperature and pressure. They also contain adhesives and resins to bind the fibres together as well as wax to make them smooth. There is no metal in MDF. The related links below may be of interest.
Hundreds of companies make glues.
In the old days hooves and tendons were used to make glues. Now most glues are made from chemical products.
It stannds for medium-density fiberboardand it is a type of wood Medium-density fiberboard (MDF) refers to a type of manufactured composite board used to make furniture, doors, flooring and walls. The making of MDF began in the United States in 1966, according to the University of Tennessee. :) If you want more type in things like history of MDF it will give you alot more
Glues and adhesives are for joining things, not for actually making something.
'Glue' is too general a term for that question. -What makes some glues soften will make other glues harden. -Please be specific about which 'glue' you mean.
A chemical called 'cyanoacrylite' is the main component of super glues. it's a derivative of the liquids originally used to make Plexiglas or Perspex and its original purpose was to join sheets of this.
yes because it is les dense than water Some glues are buoyant, others are not. It depends on the chemical make-up and typically the use for which it is meant. There are glues designed for underwater use, and buoyancy would defeat the purpose or at least make them more difficult to use.
Not any more. Glues are now made from mostly synthetic materials.
The medium's properties that affect the speed of a transverse wave include its density and elastic properties. In general, waves propagate slower in denser media and faster in more elastic media. The interaction between these two factors determines the speed at which the wave can travel through the medium.
Horse hooves used to be used, but not any more. -There are no animal parts in modern glues.
