Lining adhesives

The adhesives employed for in-line adhesive application are generally of two types (1) flexible, but non-pressure-sensitive adhesives based on blends of saturated stryenic block copolymers and wax and (2) pressure sensitives based... 

Intermediate primer or cement - A primer or cement which is part of a total tank lining adhesive system. 

Fig. 6.1. An AP-CVD system for ZnO F deposition, as developed by Hu and Gordon. DEZ and ethanol vapors are used as precursors for the ZnO formation. These vapors are transported with the help of the carrier gas Helium from their respective bubblers and then further diluted by pure helium from dilution lines. Adhesion of the films on the substrate can be strongly improved by introducing in the reactor a small amount of water. Hexafluoropropene is used as doping source. The total pressure is around 1 atm and the substrate is heated around 400° C. Reprinted with permission from [15]...

PPCC applications include deck coverings, floors, pavements, precast units, anti-corrosive linings, adhesives, patching or repairing Portland cement concretes [11, 17].

Solid sheet linings can also be applied either as an adhesive-bonded lining or a loose-fitting lining. Adhesive-bonded sheet linings on steel substrates consist of fabric backed sheets bonded to steel vessel walls with neoprene or epoxy based adhesive. Linings may be applied in the field or in the shop. Joints are heat welded using a rod of the same polymer as the sheets. 

Slow cure may also be due to a thick bond line (adhesive >0.2 mm). Cyanoacrylates are most suited to applications where the bond line is less than 0.1 mm thick although a cure through a volume up to several mm is possible using UV curing cyanoacrylates. 

The major use of EVA polymers in conservation is as additives to hot seal adhesives. Elvax 150 (Du Pont VAC 33%) and A-C Copolymer 400 (Allied VAC=15%) form the bulk of solids of BEVA 371 picture lining adhesive and consoUdant (Berger, 1976) (Figure A3.4), and has been widely applied for other types of objects (Kronthal et al., 2003 Karsten and Kerr, 2004).

Bond line adhesive layer in a bonded joint. 

Scotch-Tape" Test A method of evaluating the adhesion of a lacquer, paint, or printed label to a plastic substrate. Pressure-sensitive adhesive tape is applied to an area of the painted plastic article, which may first be cross-hatched with scored lines. Adhesion is considered to be adequate if no paint adheres to the tape when it is peeled off. 

The tire industry is probably the most important consumer of halobutyl rubbers for inner liners, tubes, tire sidewall compounds, and tire curing members. Other applications include heat resistant conveyor belts, steam hoses, gaskets, pharmaceutical stoppers, chemically resistant tank linings, adhesives, and sealants.
