BCAT-E16 is a wide applicable catalyst, with recommended to be used in 2-component polyurethane systems on almost all of CASE applications, without VOC concerns.


Features and Advantages:

BCAT-E16 is fine controlled synthetic bismuth carboxylate catalyst. The unique characteristics are as following:

◢ It can be used as a replacement for tin-based products like dibutyl tin dilaurate (DBTDL), in many cases yielding better properties than for systems catalyzed by DBTDL. Additionally, it can be used as a replacement for organic mercury or organic lead in some applications.

◢ Much better hydrolysis resistance than T9 (stannous octoate).

◢ Accelerating the reaction of NCO-OH, performing to reduce the reaction of NCO-H2O and decrease the CO2 bubbles compare with DBTDL. But for much better performance of reducing reaction of NCO-H2O, please select CUCAT series catalyst.

◢ Good compatibility, can be used alone or in combination with other metal carboxylate.


User’s Guide:

● Suggest adding in polyol component after vacuum degassing.

● Levels of 0.02-0.8% as supplied by weight on total polyol volume.

● No recommendation to add into isocyanate component. To avoid gel, please do test before adding in isocyanate component to make sure the storage stability.

● For coatings application, suggest separating packaged with supply form to get better catalytic properties.


Handling & Storage:

Exposure to atmosphere should be avoided. Please store in a cool, dry environment away from sunlight and excessive heat.


Package: 25kg/200kg in HDPE drum


Shelf Life: The unopened shelf life is 24 months from the date of manufacture.
