Different properties – a multitude of uses:

The versatility of the methacrylate backbone chemistry opens up a variety of chemical and physical properties that add performance in different application fields. The flexible and low viscous EBECRYL® PEG200DMA is the material of choice for anaerobic adhesives or liquid cure in place gaskets. While the high crosslink dense EBECRYL® TMPTMA is suitable as hardener in PVC plastisols or as crosslinker in rubber vulcanization or MMA based composite marble.
 
In addition, our EBECRYL® TMPTMA (or trimethylolpropane trimethacrylate) and EBECRYL® PEG200DMA (or triethyleneglycol dimethacrylate) are preferred diluting monomers for radical curing systems such as peroxide cured formulations. Next to UV/EB curing where typically the acrylate analogues are preferred, TMPTMA and PEGDMA are excelling in peroxide based crosslinking. 


Why use MFMAs in a nutshell?

In radical curing, such as peroxide curing, methacrylates are a preferred technology. In general, methacrylates are thermally resistant, harder, less toxic and more abrasion resistant. Multi-functional methacrylates are low viscous, stable molecules with potentially very high or low Tg (backbone design dependent).
