Adhesives


Adhesives: Glue, White Adhesive, Synthetic Resin Adhesive, Wood Working, Vinyl Acetate Based Adhesive, Wood Adhesives.

Introduction: Fevicol type Adhesive come under the category of Synthetic resins and latex Adhesives are made from Polyvinyl acetate is thermoplastic, odorless, tasteless, non toxic, essentially clear and colorless resin.


Polyvinyl acetate: It has a non Crystalline and relatively branched rather than linear structure. Most grades of resin have somewhat broad molecular weight distribution. They do not melt but soften over a temperature range. The resin is unaffected by sunlight, ultraviolet light and air, further more it will absorb a small amount of water. Polyvinyl acetate is neutral and non-corrosive.

The Various grades have good heat stability below 100ºC, show slight discoloration at approximately 150º and decompose at 50ºC show slight discoloration at approximately 150ºC but brittle at 10ºC to 15ºC. The Adhesive industry is currently the most important outlet for polyvinyl acetate.


Adhesives in various types and may be Synthetic or natural: The term Synthetic Adhesive means the Adhesive which is prepared by using Synthetic chemical such as Synthetic resin. Polyvinyl acetate is now used in Adhesives for various applications such as Book binding, Paper bag, Milk Can, Drinking Straws, Envelopes, Gummed Tapes, and Foils etc.

Vinyl Acetate Adhesive: The vinyl acetate Adhesive is also used for lamination, combination of two or more plies of material into a now composite. Polyvinyl alcohol is being imported from countries like Germany, FRP, France, U.K, Netherlands, Japan, Hungary, Italy, U.S.A and Belgium. Synthetic Adhesives Produced in India are mostly based on vinyl Acetate Monomers (V.A.M).


Vinyl Acetate Monomers: VAM is used in from of its various Derivatives like Polyvinyl Alcohol and Polyvinyl Acetate, Ethyl Vinyl Acetate etc. Currently, the major applications of Adhesives are in Furniture, Packaging, automotive and construction. Woodwork and Furniture sector has been the major growth driver for Adhesives.

Packaging is another industry: That influences the demand of Adhesives. Adhesives are primarily required in making containers and flexible Packaging. Increasing plastic and polymer use in vehicles, in order to reduce weight for enhancing efficiency will most likely drive Adhesives and sealants market size.


Packaging Applications: Packaging applications includes carton boxes, envelopes, carton closures, cups, flexible Packaging, specialty Packaging, bags and disposables, PU, water based and hot melts are widely used in Packaging applications.

To transform these into an Adhesive, they are first washed and soaked. This stock is cooked in water, cooled and re-cooked to break down the collagen into raw Glue. Chemicals, such as hydrochloric acid remove impurities in the final stages. Further heating or drying brings the Glue to a specific viscosity.


What is Adhesive made out of: Natural Adhesives are made from organic sources such as vegetable starch (dextrin), natural resins, or animals (e.g. the milk protein casein and hide-based animal Glues). These are often referred to as bioAdhesives. One example is a simple paste made by cooking flour in water.

What chemicals are used in Adhesives: It is obvious modern Glues are chemical products from the horrible names they have—polyvinyl acetate (PVA), phenol formaldehyde (PH), ethylene vinyl acetate (EVA), and cyanoacrylate ("super Glue") to name just four.


What are the types of Adhesive: Different Types of Glues:
White Craft Glue: This is the most common craft Glue for porous lightweight materials such as paper, cardboard, cloth, and kids' crafts.
Yellow Wood Glue:
Super Glue (also known as cyanoacrylate Adhesives):
Hot Glue:
Spray Adhesives:
Fabric Adhesives:
Epoxy:
Polyurethane:

What is the difference between Adhesive and Glue: In common language, Adhesive includes various kinds of chemicals, in solid, Gel or liquid forms, used for sticking two things together. The term "Glue” is generally used for liquid Adhesives.


How do you remove Adhesive: Aim a hair dryer at the sticker residue, turn it on, and allow the hot air to loosen the Adhesive. Scrape to remove. Rubbing alcohol (or vodka): If you want to know how to get sticker residue off plastic, wood, or glass, one of the most effective solvents that's safe for most surfaces is rubbing alcohol.

What is the best Glue for everything: Gorilla Glue 50004 Adhesive, 4-Ounces is the best all purpose Glue because it is extremely strong. I personally keep Gorilla Glue around at all times because of how tremendously strong it bonds things. It is unreal. Another great thing about this Glue is that once the bond dries, it is paintable and stainable.
