Rubber to metal bonding agents

The hydrohalide is liable to dehydrochlorination, particularly when moist acid is used in its preparation, so that hydrochloric acid acceptors such as lead carbonate are useful stabilisers. Dibutyl phthalate and tritolyl phosphate are effective plasticisers. Rubber hydrochloride is used as a packaging film (Pliofilm) and as a rubber-to-metal bonding agent (e.g. Typly).

Nitrile rubber is used preferably for contact adhesives with improved plasticizer resistance. Polyisobutylene is used in pressure-sensitive adhesives. Butyl rubber is sometimes added to pressure-sensitive and hot-melt adhesives, although it is mainly used in sealing compounds. Epoxy resins and reactive (meth)acrylate adhesives (reactive adhesives) are modified with polychloroprene, butyl, and nitrile rubber. Chlorinated rubber is added in small quantities to contact adhesives and also to rubber-to-metal bonding agents for improving the adhesion properties. 

Chlorosulfonated polyethylene can used in reactive adhesives in combination with (meth)acrylate monomers and also in rubber-to-metal bonding agents. 

Standard and modified phenolic resins, alkyl phenol resins, etherified phenolic resins, and phenol-terpene resins also are used as primers and resin components in other types of adhesives, for example, in contact cements, pressure-sensitive adhesives, rubber-to-metal bonding agents, and similar adhesive systems. 

Rubber-to-metal bonding agents are used for the production of vibration-damping members of rubber and metal, developing their adhesion to the metal during vulcanization of the rubber. The same applies to the production of shaft seals. Clutch and brake linings are applied by means of nitrile rubber - phenolic resin adhesives. 

At the elastomer end, it is reasonable to draw a closer analogy with rubber-to-metal bonding agents. The RLF s latex terpolymer is a diene rubber, and is likely to be vulcanized by any sulfur or accelerators that diffuse over from the carcass rubber. It has further been conjectured that the pendant pyridine rings of the same terpolymer should be attacked by the reactive R-F species. Thus, a total chemical network, but involving two or more kinds of cross-linking or covalent bonding reactions, is plausible. ...

The environment in which an article is used may influence bond durability (see also Durability fundamentals). Atmospheric ozone can cause time-dependent crack growth in vulcanized elastomers in addition, ozone can induce failure at a bond with certain bonding agents. Although water is only slightly soluble, it can permeate elastomers by an osmotic mechanism induced by salt-Uke impurities. As a result, the uptake in salt water is generally less than that in pure water. Rubber to metal bond failure has been found to occur in a time-dependent manner under salt water in the presence of electrochemical activity but much more slowly, if at all, in its absence (see also Cathodic disbondment). In the absence of imposed electrochemical activity, effects are likely to depend particularly on the metal used and its corrosion resistance. Provision of a bonded rubber cover layer over all metal surfaces subject to immersion is likely to enhance bond durability. 

Rubber-to-Metal Bonding. In the Ebonit or hard rubber process [76], the bonding agent is a reaction product of natural or synthetic rubber with 30-40% sulfur, which is thermoplastic in character, adheres firmly to metal, and provides for good adhesion to soft rubber. This process is still in use today in the lining of vessels and, to a certain extent, in the manufacture of large-diameter rolls. 

Chlorinated rubber is also an effective bonding agent. It can be used for bonding neoprene, nitrile and natural rubbers to metals. Phenol formaldehyde resins have been used alone or in conjunction with chlorinated rubbers, but curing time is lengthy.
