Additives in adhesives

Knoevenagel condensation of malonic acid with heptaldehyde [111-71-7] followed by ring closure, gives the fragrance y-nonanoic lactone [104-61-0] (6) (14). Beside organic synthesis, malonic acid can also be used as electrolyte additive for anodization of aluminum [7429-90-5] (15), or as additive in adhesive compositions (16). 

The generic name hydrocarbon resins designates several families of low molar mass polymers (M from 600 to 104) obtained by polymerization of petroleum, coal tar, and turpentine distillates [80-82], In most cases, these products are obtained by cationic polymerization of mixtures either of aliphatic and/or aromatic mono and diolefins present in the more or less enriched Cs and C9 feedstreams, or of pure aromatic monomers generally of the styrene type. They are complex mixtures of polymers ranging from viscous liquids and tacky fluids to hard, brittle thermoplastics, and are used as additives in adhesives, printing inks, rubbers, coatings, etc. [80-82], They are obviously amorphous and are characterized by their softening point (0 to —150° C), determined by standardized methods (i.e.,... 

Common applications of PCAs include high temperature lubricants, plasticizers, flame retardants, and additives in adhesives, paints, rubber, and sealants [4-6]. Table 1 shows the consumption patterns of PCAs in the United States, Canada, and Western Europe. 

FDA approved for a wide range of applications ranging from direct food additives such as chewing gum base to indirect food additives in adhesives, paper and paperboard, and polymers as per 21CFR175, 176, 177, and 178. 

Products and Uses An additive in adhesives (rubber to textile), fungicide, textiles (shrink proofing), and antibacterial. 

It should be noted that side effects are possible when using adhesion promoters/coupling agents as additives in adhesives and coatings, usually beneficial but not invariably so.
