VISIOMER® Specialty Methacrylates offers a unique modular system for tailoring desired product properties in various end use applications. The standard product range covers, alkyl/aryl (meth)acrylates, aminofunctional monomers, methacrylamides, ether methacrylates, crosslinkers, HEMA for contact lenses, wet adhesion monomers and specialty intermediates.
Alkyl methacrylate monomers are primarily used as building blocks for polymeric binders, generally known as synthetic resins. The excellent weather resistance of methacrylate polymers results from their purely aliphatic structure and effective steric hindrance of the polymer chains. There is hardly any oxidative degradation or ester hydrolysis in methacrylate polymers, as impressively demonstrated by the longevity of acrylic glass products. With our range of monomers, polymer softening temperatures can be adjusted from approx. -70 °C to 150 °C. Polymers of long-chain esters, such as VISIOMER® C17.4-MA, show waxlike polymer properties in their natural state. Esters with bulky side chains provide solution polymers with reduced viscosity, thus allowing a higher solids content.VISIOMER® EHMAVISIOMER® IDMAVISIOMER® Terra C 13-MAVISIOMER® Terra C 17-MAVISIOMER® CHMAVISIOMER® IBOAVISIOMER® Terra IBOMAVISIOMER® BNMA
These products are characterized by a minimum of two polymerizable groups in one molecule. Polymerization leads to crosslinked and insoluble structures. Allyl methacrylate offers exceptional performance with two double bonds of different reactivity, allowing graft copolymerization in emulsions. Crosslinkers are ideally suited for hot and cold curing reactive adhesives and for peroxide crosslinking of high performance elastomers due to their low volatility and high reactivity.VISIOMER® AMAVISIOMER® EGDMAVISIOMER® TRGDMAVISIOMER® PEG200DMAVISIOMER® 1,3-BDDMAVISIOMER® 1,4-BDDMAVISIOMER® 1,6-HDDMAVISIOMER® GDMAVISIOMER® TMPTMAVISIOMER® HEMATMDI
The favorable solution property of the ether functionality is combined with the high monomer reactivity of the methacrylate functionality. Unbranched ether methacrylates behave as internal plasticizers and provide polymers with very low glass transition temperatures. Due to their low volatility, VISIOMER® ETMA, THFMA and BDGMA can be used as reactive diluents for reactive systems. Long polyether side chains make the corresponding polymers water-soluble and capable of ion chelation.VISIOMER® ETMAVISIOMER® THFMAVISIOMER® BDGMAVISIOMER® C18 PEG 1105 MA WVISIOMER® MPEG 750 MA WVISIOMER® MPEG 1005 MA WVISIOMER® MPEG 2005 MA WVISIOMER® MPEG 5005 MA WVISIOMER® GLYFOMA
VISIOMER® UHP HEMA enables the production of dimensionally stable soft contact lenses with high oxygen permeability and water uptake to ensure optimum wear comfort.VISIOMER® UHP HEMA
Predominantly used in their quaternized form, these products provide water-soluble cationic polymers. Combining these products with either hydrophilic or hydrophobic co-monomers results in a wide variation of the physical properties of the resulting polymers. Copolymers containing these monomers are excellent flocculation agents and can furthermore be used as cationic thickeners.VISIOMER® MADAMEVISIOMER® DMAPMAVISIOMER® TMAEMCVISIOMER® MAPTAC
N-Methylolacrylamide is a bifunctional monomer with reactive vinyl and hydroxyethyl groups. The free N-Alkoxy group can be used for crosslinking with other functional groups such as Amide, Carboxy and hydroxyl. In addition, hydroxymethyl group readily undergo self-condensation reactions. Typical applications are the preparation of heat curable binders and emulsion polymers used in textile treatment, paper coating and leather finishes.VISIOMER® N-MMAA
The benefit of our VISIOMER® MEEU ureidofunctional monomer becomes evident in emulsion polymers that are able to provide desired wet adhesion properties. It improves the adhesion properties of the emulsion polymers, especially on wood or aged alkyd paint surfaces, as well as the wet scrub resistance of the final products.VISIOMER® MEEU 50 WVISIOMER® MEEU 25 M
