Master Bond adhesives
Konson DPG-80 Masterbatch
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Composition: 80% N,N'-diphenyl guanidine based on specification, 20% EPDM binder and dispersing agents

Use Characteristics: The curing accelerator Konson® DPG-80 gives a very long scorch time and a relatively slow full cure. It causes slight discolouration and cannot be used in light-coloured articles, except as an activator. When Konson® DPG-80 is used on its own the resistance of the vulcanizates to hot air and oxygen is poor (requiring the use of effective antioxidants). Accelerators of the mercapto type are strongly activates by Konson® DPG-80. In IIR and EPDM compounds, Konson® DPG-80 has only little effect.

Processing Advantages: The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easy quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective CBS is assured.

Dosage levels: primary: 1 - 2 phr with 2,5 - 3,5 phr sulphur; secondary: 0,1 - 0,25 phr with 0,75 - 1 phr mercapto accelerator and 2,5 phr sulphur.

Applications: Automotive and construction profile, Tire treads, air hoses, conveyor belts, footwear and other technical articles.
