SR214

A full range of specialty methacrylates for tailoring performances

 

  • Monofunctional (meth)acrylates for good elongation and impact resistance, low shrinkage
  • Alkyl difunctional (meth)acrylates for low viscosity with good solvency and outdoor performance
  • Alkoxy difunctional (meth)acrylates for high elongation and filler/pigment wetting
