Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.
Atoms combine with each other by a gum which is called attrection or called bond. the bond is like a gum or fevicol . bond or this gum have many types which is depended on atomic nature who combine. if atoms nature have metallic nature ,bond types ionic bond. if atoms have partneric nature bond types covalance bond. and third other types bond called subcovalance bond.
When was made When in when. hehheheheh
cell made a group and made a tissue and tissue together and made a musle
pyrite is made of FeS2
gums are polymeric substances whereas fevicol is a polyvinyl alchol gum .It is not a polysaccharides.
Fevicol is an adhesive marketed to carpenters that is designed to be used on woods, paper, cardboard, and fabrics. Fevicol is not water soluble. The glue has to be boiled in water before application.
When hydrochloric acid (HCl) reacts with Fevicol (polyvinyl acetate), a chemical reaction does not occur because Fevicol is a polymer made of repeating vinyl acetate units and does not contain any functional groups that can react with HCl. The HCl may not be able to break down the polymer structure of Fevicol due to the lack of reactive sites on the polymer chain. Therefore, no significant chemical reaction would take place between HCl and Fevicol.

sup ever buddy
Yes.

Fevicol is a PVA glue. PVA is relatively harmless, and the solvent is water. Some pva glues contain fungicides, so you don't want to drink it but the headline is "non-toxic".

No, You cannot mix fevicol and fevibond because both of them have different media. i.e. fevicol is water-based while fevibond is rubber-based adhesive. Aquarium has to be filled with water and so, you cannot use fevicol as fevicol is likely to melt again within few hours. Its better if you go for feviquik first and stick the glasses and then make a lining of fevibond to ensure no water-leakage.
Fevicol from the general appearance and smell looks like its is a compound of EVA Ethelene Vinyl Acetate along with some extenders, these offer excellent bonding properties and cure to a film which is peelable. The important property is that the adhesive has a porperty of whetting the substrate and hence it is excellent for porous sunstrates like wood.
