VISIOMER® methacrylates for personal & HEALTH Care

Copolymers of DMAPMA or MADAME with N-vinyl pyrrolidone are used as styling polymers in haircare applications providing a volumizing or conditioning effect.
Quats like TMAEMC and MAPTAC are used in cationic polyelectrolytes, which show good affinity to hair keratin. They are also used for cationic adjustment by copolymerization of cationic monomers with hydrophobic, non-ionic ones, leading to polyelectrolytes whose films are elastic and less hygroscopic.

Soft contact lenses are hydrogels typically composed of hydroxyesters such as VISIOMER® UHP-HEMA, crosslinkers like VISIOMER® EGDMA, PEG200DMA and TRGDMA and other comonomers to increase hydrophilicity. 
VISIOMER® UHP HEMA (ultra-high-purity hydroxy methacrylate) enables the production of dimensionally stable soft contact lenses with high wear comfort.  This is achieved by combining high oxygen permeability with high water uptake.
Our newest specialty methacrylate, VISIOMER® Terra GMMA, is a partially bio-based monomer that adds superior product properties to contact lenses when used in lens formulations.
Low shrinkage, flexibility and increased water permeability all make VISIOMER® Terra GMMA lenses significantly more comfortable for the user to wear. 

VISIOMER® multifunctional methacrylates are also ideally suited for various dental applications: Artificial teeth and dentures are manufactured using the monomer/polymer method. Here, formulations typically contain a certain amount of multifunctional methacrylates, e.g. VISIOMER® EGDMA. Composites for crowns and bridges, fillings and adhesives contain high molecular weight multifunctional methacrylates that show minimum shrinkage during polymerization, e.g. VISIOMER® HEMATMDI, as well as low-molecular-weight multifunctional methacrylates for viscosity adjustment, such as VISIOMER® TRGDMA. Dental applications also require monomers that can be light cured. Due to its reactivity, VISIOMER® HEMATMDI is one of the methacrylate monomers that is specifically dedicated to this application.
