...Classification of Adhesives: There are two main classes of adhesives: thermoplastic and thermosetting. Thermoplastic sets either my loss of solvent or by cooling. It will soften again by applying the solvent to the glue line or by re-heating. Thermosetting sets and solidifies through a chemical reaction and is irreversible. Adhesives that set at room temperature are known as 'cold-setting' and those that require heating up to a temperature perhaps in the case of pearl glue 40 and others up to 100 degrees C are known as 'hot-setting'. Types of Adhesives: Animal. Known as scotch glue (yes glue!), pearl or hide glue. Made from the hides, hoofs and bones of animals. Available now in cake or more likely supplied in small beads. It is essential for restoration work, veneering and other applications where compatibility with original artefacts is needed. Used extensively in the musical instrument industries. It is for internal use only and has high gap filling properties. Fish glue is also available which is made out of fish offal and skins. Good for small repairs. Not recommended for structural work. Casein. Manufactured from soured, skimmed milk curbs which are dried and crushed into a powder form. General joinery and woodwork use. It may stain some hardwoods and oak is particularly prone to darken. To use the powder it is mixed with cold water into a smooth creamy paste. Developed in WW2 for the manufacture of the Mosquito plane which was largely made...

...Case 37 – Baker Adhesives Background/Facts This case is about Baker Adhesives which is a small company that manufactures specialty adhesives in Newark, NJ. The setting is June of 2006. Baker Adhesives was a modest company founded by Doug Baker’s father who was a chemist and believed in flexible production systems. Baker Adhesives had recently forayed into international markets with a sale to Novo, a Brazilian toy manufacturer. Alissa Moreno was a sales manager and needed to meet with Doug to discuss the recent results. Going into the meeting Doug is excited at the prospects of finding new markets. As U.S. manufacturing continues to migrate overseas, he is under intense pressure to find new markets. This recent sale to Novo had been a financial boost to Baker Adhesives. The company was able to easily meet the order and in fact it freed up some raw material the company had in inventory. The purpose of the meeting was to finalize details on a new order from Novo that was to be 50% larger than the original order. When the meeting started, Moreno hit Baker with the bad news immediately. The problem was that since Novo order was denominated in Brazilian, the payment from Novo had to be converted into U.S. dollars at the current exchange rate. Exchange rates had changed since the time Baker Adhesives and Novo had agreed on a price, the value of the payment was now substantially lower than anticipated. This was going to hurt profit. So obviously Baker was...

...Chapter 1 INTRODUCTION A.Background of the study The use of adhesives offers many advantages over binding techniques such as sewing, mechanical fastening, thermal bonding, etc. These include the ability to bind different materials together, to distribute stress more efficiently across the joint, the cost effectiveness of an easily mechanized process, an improvement in aesthetic design, and increased design flexibility. The researcher will make glue out of milk to improved the stickness of milk. An adhesive is any substance applied to the surfaces of materials that binds them together and resists separation.Adhesives may be found naturally or produced synthetically.These are then organized into reactive and non-reactive adhesives, which refers to whether the adhesive chemical reacts in order to harden. Alternatively they can be organized by whether the raw stock is of natural or synthetic origin, or by their starting physical phrase. Adhesive is classified in different material like glue,cement, beewax etc.Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. The researcher chooses this project because I'm interested of this topic. I know that this project is already been done by other people.Adhesive play the important role of the stickness of the raw materials to improved the joined material.This...

The macro-environmental factors that influence Nike’s strategy include culture, demographics, social issues, technological advances, economic situation, and political and regulatory environment. Culture is the shared meanings, beliefs, morals, values and customs of a group of people. In America, Nike has become an industry leader that influences our cultural practices. It is widely accepted as the premier retail brand by all age groups. Nike has done a great job of advertising to various generational cohorts and expanding its brand. Nike’s distinguishable products have become a household name on the global scale. Nike has to specifically consider the “country culture” of not only the countries where it sells product, but the cultures of the countries where the products are manufactured. Country culture attributes include behavior, dress, symbols, physical settings, ceremonies, language, and colors. Identifying and navigating some of the more subtle aspects is difficult but necessary for global firms.

...[13] In Europe, glue fell into disuse until the period 1500-1700 AD. At this time, world-renowned cabinet and furniture makers such as Chippendale and Duncan Phyfe began to use adhesives to hold their products together.[11] The development of modern adhesives began in 1690 with the founding of the first commercial glue plant in Holland. This plant produced glues from animal hides.[14] Liquid animal glue In 1750, the first British glue patent was issued for fish glue. The following decades of the next century witnessed the manufacture of casein glues in German and Swiss factories.[11] In 1876, the first US patent (number 183,024) was issued to the Ross brothers for the production of casein glue.[11][15] Casein glue preparation The first US postage stamps used starch-based adhesives when issued in 1840. The first US patent (number 61,991) on dextrin (a starch derivative) adhesive was issued in 1867.[11] Natural rubber was first used as material for adhesives starting in 1830.[16] In 1839, Charles Goodyear discovered that a rubber and sulfur mixture, when heated, becomes elastic. In 1843, Thomas Hancock named this process vulcanization. In 1862, a British patent (number 3288) was issued for the plating of metal with brass by electrodeposition to obtain a stronger bond to rubber.[14] The development of the automobile and the need for rubber shock mounts required stronger and more durable bonds of rubber and metal. This spurred the development of cyclized rubber...

...FACT: It’s almost healthy to eat glue Posted by Ryan Pilling on Mar 2, 2011 in Interesting Facts | 1 comment In the exciting world of adhesives, glue is the organic side of things. Technically, for something to be a true “glue” it will get its sticky quality from an animal or vegetable ingredient. The classic example is sending an old horse to the great glue factory in the sky. In fact horse hooves, along with bone, hide, and connective tissues, provide collagen as the main ingredient for glue. (in all mammals, including you dear reader, over 25% of the protein content is collagen) The process of turning pony toes into glue is, to boil it down, essentially… boiling it down. The collagen leaks out in a jelly-like form, is collected, and ground into powder. When you’re ready to make antique furniture, you mix it with a bit of water, heat it up, and you’re ready to brush it on your joins. Collagen glue like that has been used for at least 8000 years, and has only been replaced by chemical adhesives for common use in the past century. Vegetable glue, commonly called paste, is an even simpler recipe: starch and water. The starch most commonly used is corn starch, but white flour works as well. When sticking things together, the best adhesive is one that shares chemical properties of the items you want to make stick. That’s why paste works so well with paper. The starch, which is a carbohydrate, is similar to the carbohydrate cellulose that forms the paper...
