是的，互通有无啊，

你们家什么产品啊，搞得那么神秘？

哈哈，也没什么，环氧聚氨酯都有，以前做销售，现在转技术了，

wu246246

想做一段技术了突然，产品照卖，树脂什么的

liu123quan

可以理解的，环氧合聚氨酯有很多相似的地方，问题不大

liu123quan

ACCC了解过吗，现在做这个得很多啊

昨天在上海跟张风翻张总工一块吃了个饭，说我的促进剂也大有可为，现在也介绍一下
HYCATTM3000/3000S
低温环氧固化和改性环氧促进剂


产品名称：HYCATTM3000/3000S

生产商及产地：DTCS,lnc.美国

产品简述：
HYCATTM3000/3000S是一种基于Cr3+络合物的高效促进剂浓缩液。由于其独特的改性配方，使得HYCATTM3000/3000S在酸酐固化配方中具有良好的溶剂性，从而保证了优异的固化均匀性。在通常1%-5%加入量时，可以在低温或略高于室温的条件下（15-50° C）使得环氧基团（如双酚A或溴化双酚A结构）与酸酐、羧酸、羧基、环胺、酰胺等各种固化剂快速开环与固化。也可以在中高温下快速固化，根据添加量固化时间可在几十秒到几分钟内完成。在使用HYCATTM3000/3000S时，极少发生环氧的自聚反应，产品的副反应被大大抑制，交联固化体系的机械性能显著提高。

Hycat™ SM3
An Excellent Catalyst for High Temperature Epoxy Cures
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.
