I have a real excellent new product today. The German company Peter Kwansy has brought their Spray Max line of primers to the United States. The revolutionary step is Spray Max is real 2K primer in a spray can. We have been selling 1K urethane primer in a spray can for a while now and all though it is a major advance over lacquer primer it was still single component primer. With the Spray Max primer we are now able to a have real 2 component product in a spray can.
There are three different primers an epoxy, a direct to metal epoxy and urethane. The trick is in the can there is a smaller compartment in side the can and when you activate the two parts mix together.
These primers will give high build, good color hold out and great chemical resistance. Use the epoxy when you need the best adhesion, the urethane for maximum flexibility and the direct to metal when you are down to bare metal.
As you can see in the diagram the inner container is activated by taking the red plunger out of the cap and pushing on the bottom valve, this releases the second component and after shaking vigorously you have primer. The can says you have 8 hours to use it before it hardens.
They promise we will see 2K urethane clear soon. It's on the boat just over the horizon.
