System Three Slow Hardener is a No-Blush hardener that works well in a temperature range of 65 to 90 degrees Fahrenheit. At 65 degrees, you will have a 10 hour green cure stage that will allow you to recoat without sanding or washing. The next coat will chemically bond to the uncured epoxy.
When selecting a hardener consider the minimum temperature expected during application and cure time in relation to pot life. Combine System Three hardeners to create a continuous range of cure times within the parameters of the Fast, Medium and Slow.

Questions & Answers about System Three Slow Hardener:
2011-10-18A shopper asked: What is the ratio of hardner to resin? Thanks
+Expand Answers
2011-10-18CHRISTOPHER CARLSTROM: This is a 2 to 1 ratio, 2 parts resin to 1 part hardner, curing works well if the curing temperature is elevated to ~150F
2011-10-18SCOTT MOSHER: The ratio for system three epoxy is 2 parts resin to 1 part hardener, whether you use the slow, medium, or fast hardener.
2011-10-18HENRY RUSSELL: The ratio is 1 to 2, hardener to resin. The speed that the resin sets is controled by the type of hardener used. I hope this helps.
2011-10-18JUDD FULLER: 2:1. Resin to hardener. It's in the directions on the label. Only way I know.
2011-10-18PAUL DENK: The recommended proportion is two parts resin to one part hardener. Since the manufacturer says the ratio is critical, I never experimented with changing it.
2011-10-18HENRY HALL: One part hardener to two parts resin.
2011-10-18TOM HORNKOHL: Two parts resin to one part hardner. Graduated disposable measuring cup recommended.
2011-10-19DAN MCINTYRE: 3:1 for normal use. if you need a shorter pot time because it cold you can use 4:1 but do not leave it in the pot after mix more that 5minute
2011-10-19JAMES LAWSON: 1 part hardner to 2 parts resin.I bought the 2 pumps that measure the right ratio.They worked well,but make sure they have time to refill.I pump one part hardner and then pump one part resin.That makes the mixing easier because of the layers and gives the pump time to reload.
2011-10-19PATRICK BARMES: 1 part hardener to 2 parts resin. You can always contact System Three and they will give you specific information relating to the type of hardener you have purchased to the resin you intend to use...

Measuring Part A and B by weight produces extremely good results. If you use pumps to remove the product from the jugs, prepare for a small amount of dripping after each use. 100% isopropyl alcohol cleans up messes very well.
