![]() ![]() An additional advantage of Trigonox 421 is that all decomposition products that are generated are non-toxic, which is in contrast to AIBN which forms toxic TMSN. Our Trigonox 421 provides similar technical performance and is a sustainable alternative for AIBN. Perkadox® AIBN can also be used for pharmaceutical and fine organic synthesis. Our most commonly used initiator is AIBN, but our AMBN provides even better solubility than AIBN. They do not form oxygenated residues and do not cause oxidative degradation of pigmented or dyed systems.Ĭompared with organic peroxides, azo initiators avoid excessive grafting, making them particularly suitable for use in manufacturing acrylic cast and moulded sheets, as well as adhesives, acrylic fibers, super absorbers, detergents and flocculants. ![]() For this reason, the color stability or transparent, dyed polymers, such as polymethylmethacrylate, is improved.ĪIBN and other azo initiators provide excellent color stability in transparent colored polymers, such as PMMA. Perkadox® AIBN does not form oxygenated residues and does not cause oxidative degradation of pigmented of dyed polymer systems. This provides low Poly Dispersity Index (PDI) values and molecular weights. Heat curing adhesives consist of a pre-made mixture. Azo initiators generate only C-centered radicals, which are low energy and very selective and cause a low amount of branching. However, water-based adhesives are still of strong interest as they. Our most commonly used initiator is AIBN, but our AMBN provides even better solubility than AIBN.Īdvantages of AIBN initiators: Azo initiators have many advantages over standard organic peroxides, such as the fact that they form no oxygenated byproducts and provide low yellow discoloration. They are milled to a tiny particle size and do not dissolve, but remain suspended in the paint. There are three main components in any acrylic paint - pigment, binder and vehicle: Pigment - pigments are granular solids which give paint its color. We offer azo initiators, such as Perkadox® AIBN (azobisisobutyronitrile) and Perkadox® AMBN (2-methylbutyronitrile), for bulk, solution, suspension and emulsion polymerization of a wide variety of monomers, such as styrene, vinylchloride, vinylidenechloride, acrylonitrile, acrylates and methacrylates. Water-based acrylic paint is composed of pigment particles dispersed in an acrylic polymer emulsion. ![]()
