Evonik DYNACOLL® AC 4830 Polyacrylate
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Adhesives, Sealants, and Coatings
Material Notes:	Polyacrylates: With its DYNACOLL® AC product range Evonik offers acrylics for one-component moisture curable hot melt adhesives. Acrylics for adhesives are bead polymers made of methyl methacrylate and n-butyl methacrylate which are mainly used to modify reactive hot melts for flat lamination applications. Various DYNACOLL® AC grades with tailored glass transition temperature and molecular weight are available. They also differ according to their acid and hydroxyl functionality. DYNACOLL® AC polyacrylates are supplied as beads in bags of 25 kg. Your benefits DYNACOLL® AC provides outstanding quality and flow properties DYNACOLL® AC modified reactive hot melts provide low viscosity very long open time aggressive tack high creep resistance directly after bonding Applications: DYNACOLL® AC grades are mainly used to modify reactive hot melts for flat lamination purposes. Typical areas of application are: Sandwich composites: of aluminium, FRP panels, foam or wood-based substrates e. g. for recreational vehicals Honeycomb structures: e.g. for door manufacturing Foil laminated particleboard: e.g. for furniture Medium density fiberboard panels: e.g. for furniture Flat lamination applications require long open times to permit long handling times needed to bond huge panels or sandwich composites. On the other hand, initial strength has to be very high to hold the bonded parts in place without any further mechanical fixation. Information provided by Evonik
