Curing agent neoprene

Selfelastomeric materials may be compounded and calendered with a chemical curing agent which will, over a period of time, slowly cure the sheet at ambient temperatures. This type of curing is primarily noted in natural rubber and neoprene sprayed and troweled coatings, and has not, in recent years, been, to the writer s knowledge, employed for total cure of sheet linings. 

Adhesives used to bond acetal homopolymer to itself and to other materials, such as aluminum, steel, natural rubber, neoprene rubber, and Buna rubber, include polyester with isocyanate curing agent, rubber-based adhesives, phenolics, epoxies, modified epoxies, and vinyls. Solvent cementing... 

The following compounds were identified in a range of Neoprene samples (Table 1.4), NSA carbon black filler, Sundex 8125 processing oils, Wingstay 300 antiozonant, Wingstay 100 antioxidant and sulfur curing agent. 

Terpene phenolic resins, such as Schenectady s SP-560 or Occidental s Durez 12603, are also often used in Neoprene adhesives. They are nonreactive and thermoplastic in nature and so provide longer open tack time and a softer glue line than the f-butyl phenolics, but offer less hot cohesive strength. Terpene phenolic resins are often used in combination with a polyisocyanate curing agent, such as Bayer s Desmodur RF, in a two-part adhesive system to obtain better hot bond strength. 

One-part compositions contain up to 35% neoprene. Storage life is extended by reducing the levels of curing agent and by dilution with... 

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.
