Use for making Engine plenum. Call to Mfr they insist on post cure of 50F rise per hr until 300F, then back to room temp to get the full Hi Temp capability. Thick like honey, but still wets very well. Very slow to cure, need to have heat lamps or heater to help cure. Will take 24hrs for sure even with heat lamps. Get heat lamps from chicken section at TSC! They Work great!!!

HtR212/H386-99 Resin Quart
Great online catalog. Easy to use. Fast delivery.
I use this resin extensively throughout our mid-sized UAV. I have always preferred MGS 285, but HTR works great for most parts and wets out almost as well. Unfortunately no choice of hardeners. Pot life is just long enough to layup wing-skins or thick, complicated carbon components Maybe 1hr tops before closing the mold or pulling vacuum. I really love the high temp resistance of this resin compared to MGS. Need to debond a fitting or joint? Hit it with the heat gun and pull it apart. The HTR part is uneffected, while West sys, 3M DP420 and others turn to putty. Simply put A pleasure to work with!

This is a kit, which has the resin and hardener. It is a room temp cure epoxy system.
This kit comes with HTR-212 Resin and HT-386-99 hardener.
Per the supplier: This resin is very clear. Most people use it for aftermarket parts. A lot of racing people like it as well. Viscosity at room temperature is about 1200cps. It wets out very nicely.
