Effect of Accelerator Type on Brass-Rubber Adhesion
This indicates that TMTD corrodes brass to a much greater extent than the MBS accelerator. From the data presented, the following conclusions can be drawn: (1) The poor adhesion to brass of TMTD accelerated compounds is not related to: (a) their rapid cure rates, (b) a lack of synchronization between cure rate and sulfidation rate, or (c) crosslink density or type.

Mechanism of Rubber-To-Brass Adhesion : Effect of Rubber
The adhesion is explained on the basis of an autocatalytic effect of a thin film of cuprous sulfide formed on the brass surface by the combined action of sulfur and vulcanization accelerator. This film transfers sulfur atoms to rubber molecules, which results in a high rubber surface polarity.

Study of the Compound Effects on The Adhesion Layer
Study of the Compound Effects on The Adhesion Layer on Brass By GPC and TOF-SIMS ABSTRACT Compound effects on the sulfidization reaction of brass were studied by GPC and TOF-SIMS using a squalene reaction medium. The absence of carbon black and cobalt salt retarded the decomposition reaction of accelerator and crosslinking reaction of squalene.

Factors in rubber compounds affecting the adhesion
Sulfenamide cure accelerators and water were found to be synergistic in reducing the retained adhesion of polyester cord after in鈥恟ubber aging at high temperatures. The harmful effects of amines released from sulfenamides during curing and heat aging were eliminated by compounding the stocks with accelerators that do not form amines.

Bond failure between rubber and brass-coated wire
Thmram accelerators grossly interfere with chemical bonding to brass Integral bonding additives and their effect on rubber/brass adhesion In recent years it has become possible to formulate rubber such that it will self-bond to various non-rubber substrates without the pnor use of adhesives and pnmers by incorporating additives that promote chemical bonding between rubber and substrate into the m=x.

Studying the pulverization mechanisms of low-cross-link
The effects of the temperature in the different heating zones and the rotating speed of the screw in the Solid State Shear Extrusion (SSSE) process were studied. Results showed that providing a range of both temperature and normal stress was required to pulverize cross-linked natural rubber, but shear stress plays the most important role to produce fine particles.
