Animal-hide glues

The head of a safety match consists of K chlorate 45-55, animal (hide) glue (as a binder) 9-11, sulfur or rosin 3-5, extender (starch, dextrin) 2-3, neutralizer (ZnO.or Ca carbonate) 45-55, infusorial earth 5-6 other siliceous filler 15-32%. Fractional percentages of a soluble burning rate catalyst, such as K di-chromate, also soluble dye stuffs, etc...

Animal-Hide Glues, This category includes hot and liquid animal-hide glues, as well as other water-soluble animal gelatins (e.g., fish and rabbit-skin glues). 

Candidates in the water-based group include the hot and liquid animal-hide glues, poly (vinyl acetate) emulsions (including the more reversible kids glue ) and other water-soluble natural or synthetic polymers (e.g., starches, natural gums, cellulose esters and ethers, soluble nylon). 

Among water-soluble or water-dispersible binders are dextrins, gum arabic, casein, and animal hide glue. The latter has received great attention from the match manufacturers as well as from other industries. Hide glue is marketed in a great variety of viscosi-...

At the present time the largest consumer of animal hide glue is the abrasives industry. Abrasives are involved in the enormous production... 

The first coated abrasive made goes back to the 13th Century, when the Chinese used crushed seashells as an abrasive grain and bonded them to parchment paper with natural gums. Other forms of coated abrasives were made by applying abrasive minerals to animal skins, leather, etc., and as time passed, animal hide glues and varnishes were used to bond grain to paper and cloth. 

In order to take advantage of the new abrasive grit materials, new and improved bond systems had to be developed. Subsequently, adhesive systems have also come a long way, progressing from fish and animal hide glues to urea-formaldehyde resins, epoxies, phenolic, and radiation-curable systems. This evolution has placed a continuing demand on the adhesive systems used in the manufacturing of abrasive products.

Many glues, especially those commonly used in conservation work, harden primarily by an increase in concentration of the glue s polymer solids as the carrier (water or solvent) is lost into the substrates and surrounding air. Glues based on water-soluble or dispersible polymers (e.g., starch, casein, animal hide gelatin, and cellulose esters and ethers) would be in this category. 

Animal glues are derived by the hydrolysis of the protein constituent collagen of animal hides and bones. Collagen in its natural state is water insoluble and must be conditioned to solubilize the protein. Collagen molecules are triple helices of amino acid sequences and contain both nonpolar and charged acidic and basic side chains. The conversion of... 

Basic manufacturing procedures for animal glues generally involve alkaline pretreatment (for hide glues) or acidic pretreatment (for bone glues). The raw materials for hide glues...

Glue made of the collagen of animal hides and skins is widely used as adhesives. Soluble collagen is used extensively in the cosmetics industry as the basis for face creams, lotions and hair formulations.
