man it is not the color ..which matters the colour depends on the indicator.. in the pH scale O is very acidic and 14 is very basic.7 is neutral. pH do not depend on colour.absolutely no relation.........eg : neurotic acid with pH zero is plain like water. Here is another attempt to answer your question: http://en.wikipedia.org/wiki/Universal_i...
Acrylic Adhesives. Acrylic adhesives can either be water-based (this is also referred to as emulsion or dispersion) or solvent-based. Water-based are slower drying compared to solvent-based systems but generally solvent-based acrylic systems have better resistance to other solvents, chemicals and water.
Acrylates contain vinyl groups, that is, two carbon atoms double bonded to each other, directly attached to the carbonyl carbon. Acrylates and methacrylates (the salts and esters of methacrylic acid) are common monomers in polymer plastics, forming the acrylate polymers.crylates are the salts, esters, and conjugate bases of acrylic acid and its derivatives. They are also known as propenoates (since acrylic acid is also known as 2-propenoic acid).
