You can adjust the hardening time of polyester resin somewhat by altering the amount of MEKP hardener you add. The more hardener, the faster it sets. You can add too little hardener and it will never set. However, there is a wide range of hardener concentrations that work fine. If you have a piece that isn't setting due to cold weather or short hardener you can set the piece in direct sunlight. UV radiation will set off this resin seems like no matter how much hardener is used. Be careful with this though, the resin setting chemistry gives off a lot of heat and too thick a part, too much hardener and/or solar acceleration can get the thing smoking and even start a fire! | You can adjust the hardening time of polyester resin somewhat by altering the amount of MEKP hardener you add.

Made with orthopthalic acid, ortho is what you get if you don't specify anything else. Fine for most everything in hotrodding. | Made with orthopthalic acid, ortho is what you get if you don't specify anything else. Fine for most everything in hotrodding. | ||
