是的，互通有無啊，

你們家什么產(chǎn)品啊，搞得那么神秘？

哈哈，也沒什么，環(huán)氧聚氨酯都有，以前做銷售，現(xiàn)在轉(zhuǎn)技術(shù)了，

wu246246

想做一段技術(shù)了突然，產(chǎn)品照賣，樹脂什么的

liu123quan

可以理解的，環(huán)氧合聚氨酯有很多相似的地方，問題不大

liu123quan

ACCC了解過嗎，現(xiàn)在做這個(gè)得很多啊

昨天在上海跟張風(fēng)翻張總工一塊吃了個(gè)飯，說我的促進(jìn)劑也大有可為，現(xiàn)在也介紹一下
HYCATTM3000/3000S
低溫環(huán)氧固化和改性環(huán)氧促進(jìn)劑


產(chǎn)品名稱：HYCATTM3000/3000S

生產(chǎn)商及產(chǎn)地：DTCS,lnc.美國

產(chǎn)品簡述：
HYCATTM3000/3000S是一種基于Cr3+絡(luò)合物的高效促進(jìn)劑濃縮液。由于其獨(dú)特的改性配方，使得HYCATTM3000/3000S在酸酐固化配方中具有良好的溶劑性，從而保證了優(yōu)異的固化均勻性。在通常1%-5%加入量時(shí)，可以在低溫或略高于室溫的條件下（15-50° C）使得環(huán)氧基團(tuán)（如雙酚A或溴化雙酚A結(jié)構(gòu)）與酸酐、羧酸、羧基、環(huán)胺、酰胺等各種固化劑快速開環(huán)與固化。也可以在中高溫下快速固化，根據(jù)添加量固化時(shí)間可在幾十秒到幾分鐘內(nèi)完成。在使用HYCATTM3000/3000S時(shí)，極少發(fā)生環(huán)氧的自聚反應(yīng)，產(chǎn)品的副反應(yīng)被大大抑制，交聯(lián)固化體系的機(jī)械性能顯著提高。

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.
