LATEX BASED RUBBER ADHESIVES WITH PROCESS AND FORMULAE

Latex based adhesives are of special importance for cementing porous surfaces due to their ability to wet such surfaces. On the other angle the porosity allows the latex adhesive to dry out thus producing a strong coherent film.
Sodium silicate, glue, albumen gums and starch etc. are compatible with natural latex and exert a stabilizing action. The latex rubber in the adhesive film imparts flexibility and strength and protects and bond against dynamic fatigue.
Latex based adhesives contain a rubber latex, adhesion modifiers, plasticizers, curatives, fillers such as whiting and kaolin, thickness e.g. cellulose derivatives and other additives e.g. antioxidants, surfactants antifoams (Octyl alcohol, silicons), antifreeze, stabilizers corrosion inhibitor colourants, deodorants and reodorants etc.
Shoe industry, both or leather and rubber based types, utilities quite a good amount of adhesives, large number of which are based on animal glues, now-a-days various thermoplastic materials other than those based on animal glues are in use, e.g. adhesives based on PVC, polyvinyl butyl, rubber natural and synthetic, methyl cellulose and celluloid etc. Water resistant casein glues are also employed for this purpose.

The rubber solution which are manufactured by synthetic rubber are called as “synthetic rubber adhesives”. It is an important item for shoes and rubber industries in the joining of two layers or more than two rubber layers of shoe layers or shoe parts and soles. The rubber solutions have some public uses also, such as, in cycle puncture and heavy vehicle puncture fixing.

Rubber cement is a solution of unvulcanized (gum) rubber in a solvent, and is used as an adhesive. Ideally, it is meant to join two pieces of rubber together, which involves a chemical cohesion process. When joining two pieces of rubber, only one surface has to be coated with rubber cement since they are the same material. However, when joining paper together, both pieces need to be covered with rubber cement. When rubber cement dries, only the parts in contact with the paper remain, which holds the two pieces together. Despite this limitation, the household type of rubber cement finds wide use for applications such as mounting photographs. Unlike with white glue, the joined pieces of paper can be pulled apart without damaging either piece.

Adhesives are made from either natural animal or plant products or synthetic polymer. Natural adhesives are easy to apply and in general are water soluble.

Synthetic adhesives are divided into four chemical categories: thermoplastic, thermosetting, elastomeric, and combinations thereof. Thermoplastic adhesives, such as polyvinyl alcohol and acrylics, can be resoftened since the materials do not crosslink upon curing. They require heat or a solvent to create a bond.

Thermosetting adhesives, which include epoxies, cannot be heated and resoftened after curing because they do crosslink upon curing. Elastomeric adhesives are based on isoprene rubber or synthetic polymers that combine both elasticity and toughness. Silicone is a typical example.
