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.
Best Answer: There are three main types of Glue; Water based, Solvent Based, Chemical curing. Water based glues are made of natural or synthetic polymers, mixed in water, and are used when one of more surface is porous (e.g. wallpaper paste). They are slow to dry and will not stick non-porous materials like plastic.Water based adhesives are typically made of Water, Polymer, Thickener, Additives to improve strength Solvent based glue are a synthetic adhesive polymer mixed in solvent. They are used to stick non-porous surfaces and are fast drying.ater based glues are made of natural or synthetic polymers, mixed in water, and are used when one of more surface is porous (e.g. wallpaper paste).
