An Excellent Catalyst for High Temperature Epoxy Cures |

Hycat™ SM3
One major problem encountered with some catalysts used in high temperature (>200 OC) epoxy cures is the tendency to form a rough surface, bubbles or voids due to the volatilization of low boiling components contained in the catalyst or decomposition of the catalyst. Hycat™ SM3, produced by Dimension Technology Chemical Systems, Inc., has effectively eliminated this problem. For example, in a formulation containing a cycloaliphatic diepoxy (Lindride 190) and MHHPA (Lindride 52D) catalyzed with 4% DBU (1,8-Diazabicyclo [5.4.0] Undec-7-ene) the reaction completely decomposed at 200 OC and bubbled over the test pan.
Although using Hycat™ 3000S in the same formulation gave quick cures that were under 3 minutes at 200 OC, bubbles were formed on the surface and the weight loss of the cured product was substantial at 2%. But using the newly developed Hycat™ SM3 catalyst these problems were eliminated. As can be seen in the photos below, the cure (<3 minutes) results in a smooth surface and is free of entrapped bubbles. Using Hycat™ SM3 the weight loss of the product was less than 0.2% and gave a Durometer-D hardness of 86.
Hycat™ SM3 is an excellent catalyst where high temperature quick cures are needed.
