MEKP Liquid Hardener

A:

I'VE GOT TO SAY IT IS ABOUT THE SAME AS WATER

A:

The viscosity of the MEKP is relatively low, not quite as thin as water but only as viscous as a very light oil.

Unfortunately, I was using this for waste treatment process and not for producing viable resin, so I can not help you with the ratio part of the question.

A:

This is not an easy question to answer. The number of drops per ounce depends on the volume of resin being mixed and the thickness of the pour. I use 5 drops per ounce when pouring 2 - 3 ounces of resin. If you want to pour a thin layer ( 1/8") the number of drops must be increased. Here is a guide of drops to thickness:
1/8" - 15 drops
1/4" - 8 drops
1/2" - 6 drops
3/8" - 5 drops
1 - 1/2" 4 drops

The viscosity of MEKP is water thin. Be sure to mix in a well ventilated area and wear a fume respirator if mixing in your shop.

Hope this helps. John

A:

The ratio is dependent of the temperature. Optimal temperature for applications is 70 deg F. At that temp, 1 oz resin to 2 drops of Hardener, with a cure time of 10 minutes. At 60 deg F, it should 4 drops per 1 oz resin and will take about 30 minutes to harden. Below 60 degrees, I have found it eventually hardens, but does not bind to the repair surface. At 80 and above I use 1 drop/1 oz resin, but have to work really fast. Its best to plan your work, and act when the temp is optimal. This is applicable for resin only, or resin/cabosil mix. The viscosity of MEKP is like water, so it turns the gel from pasty to wet..
