Glues furniture manufacture

Figure 1. Chain-link diagram of well-formed (proper) wood-glue joint. The materials and conditions that were used have led to a joint with good bulk wood strength, a strong interphase with good adhesion, and a strong glue film. (Reproduced with permission from ref. 1.

Para-tertiary-buty pheno formaldehyde resin (PTBP-F-R) is a polycondensate of para-tertiary-butylphenol and formaldehyde. Major occupational sources are neoprene glues and adhesives in industry, in the shoemaking and leather industry or in car production. It is also used as a box preservative in box and furniture manufacture, and in the production of casting moulds, car-brake linings, insulated electrical cables, adhesives, printing inks and paper laminates. Para-tertiary-butyl-phenol is the sensitizer. 

A great deal of chemical transformation takes place before consumers receive their furniture, flooring, and other indoor building materials. Polymerization of glues, coatings and plashes, or heat processing of manufactured wood products, generates volatile by-products that can continue to be emitted from the material after it has been installed. Once installed, further transformations increase the load of odorous or toxic gas-phase species (Uhde and Salthammer, 2007). Reactions discussed here include oxidation and hydrolysis. 

Can be released as point source pollution during manufacture, transportation and end use. Additionally, consumers may be exposed to phthalic anhydride from the use of plastics, furniture, glues, coatings and home products from which phthalic anhydride may leach, and/or upon disposal of the products. 

Adhesive Assembly n An adhesive that can be used for bonding parts, such as in the manufacture of a boat, airplane, furniture, etc., NOTE - The term, assembly adhesive, is conunonly used in the wood industry to distinguish such adhesives (formerly called joint glues ). It is applied to adhesives used in fabricating finished stmctures or goods, or subassemblies thereof, as difierentiated fi-om adhesives used in the production...
