Graco Inc.

M2K Proportioners  Fixed Ratio, Entry Level Mechanical Proportioner

Ideal for lower volume two component epoxy, polyurethane and polyester materials

Where to BuyRequest Info

Graco’s new M2K proportioning system eliminates hand mixing in an easy to use, compact design. This fixed ratio machine keeps your mix ratio consistent, minimizing flush time, material waste and clean up associated with hand mixing. Plus there’s a version specifically designed to manage split batch polyester materials.

  • Increase mix material accuracy to improve finish quality and reduce material waste, compared to hand mixing
  • Compact size makes it faster and easier to flush, saving you time and disposal costs
  • Ideal for lower volume two component epoxy, polyurethane and polyester materials
  • Proven reliability on key system components, including our Merkur air motor
  • Choose from air spray, air-assist and airless spray technologies
