Adhesive Meant to Adhere: Types of Adhesive
Adhesives are meant to stick things together. An adhesive is a compound that adheres or bonds two items together. Adhesives may come from either natural or synthetic sources. Adhesives are nature product; it is also manufactured in Factories. Some modern adhesives are extremely strong, and are becoming increasingly important in modern construction and industry.
Now the Scientific Reason behind their capability to make things stick? The simple answer is Chemical Reaction. Wood, paper, and many other materials have small cracks and holes in them. When we glue things together, sometimes the glue seeps into the tiny openings and hardens, making the materials stick together. The molecules on the surface of an object get tangled up with the glue molecules, making the objects stick together.
- Natural adhesives: are made from inorganic mineral sources, or biological sources such as vegetable matter, starch (dextrin), natural resins, animal skin, or a mix such as casein + lime. They are often referred to as bioadhesives.
- Synthetic adhesives: Elastomers, thermoplastic, and thermosetting adhesives are examples of synthetic adhesives.
- Drying adhesives: These adhesives are a combination of ingredients suspended in a solvent. White glue and rubber cements are members of the drying adhesive family. As the solvent evaporates, the adhesive hardens. Depending on the chemical composition of the adhesive, they will adhere to different materials to greater or lesser degrees. These adhesives are typically weak and are used for household applications. Some adhesives intended for use by small children are now made non-toxic.
- Contact adhesives: Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adhesives require as long as 24 hours to dry before the surfaces are to be held together
- Hot Glue: Also known as "hot melt" adhesives, these adhesives are thermoplastics; they are applied hot and simply allowed to harden as they cool. These adhesives have become popular for crafts because of their ease of use and the wide range of common materials to which they can adhere. The glue gun melts the solid adhesive and then allows the liquid to pass through the "barrel" of the gun onto the material where it solidifies.
- UV and light curing adhesives: UV and light curing adhesives consist essentially of low or medium molecular weight resins.

Im trying to make hot ice. How much sodium acetate and water do i use?
Take any sod acetate and add water (3times its amount) and now by process of crystallization prepare sod acetate trihydrate. Now melt these crystals. This forms a supersaturated solution called hot ice. Now dip a metal tip in middle rapid crystallization of sodium acetate occurs.
