EGE Kimya offers a range of metal-based catalysts to be used in polyurethane industry. These catalysts can be divided into two groups; first class of which are used in PIR (Polyisocyanurate) application and rest are developed to be used in CASE (Coatings, Adhesives, Sealants, Elastomers) application, high density foam, spray applications, microcellular and rigid foam.
EGECat® 239 and EGECat® 2269 are potassium acetate and potassium octoate solutions in diethylene glycol. Having been known as isocyanate trimerization catalyst, both catalysts promotes isocyanurate reaction and are used in a wide range of rigid foam applications.
The rest of the series are designed to be used in a wide range of applications like CASE (Coatings, Adhesives, Sealants, Elastomers) application, high density foam, spray applications, microcellular and rigid foam.
EGECat® DBTDL-S, DBTDL is the tin catalyst which is used for widest range of applications. Hydrolysis resistance is low when it is compared with the alternative catalyzers.
EGECat® Tin-S, is used especially for flexible foam applications which provide the high gelling effect in the reaction.
EGECat® Bismuth Octoate, is the environmental friendly gelling catalyst which is used in polyurethane applications.
EGECat® Bismuth-S is a selective urethane gelling catalyst, which accelerate the reaction rate and cause rapid gelling. It is a bismuth based catalyst which is more selective than tin and provides better mechanical properties. It can be used as a co-catalyst with a tertiary amine to accelerate the urethane reaction and presents a gradual increase of the viscosity (no induction period of low viscosity as mercury).
EGECat® Zinc-S is another catalyst that accelarates the reaction between polyol and isocyanate component, providing the optimal control of the drying properties, both during forced-drying and curing at room temperatures. It is a cross-linking catalyst which enables the modification of the final network, affords tack-free surface. It exhibits synergistic activity with bismuth catalyst, improve solvent resistance, increases film hardness. It is offered as an alternative to DBTL an in many cases yielding better properties than DBTL. Use of this product often provides a prolonged pot life at comparable drying times.
EGECat® Zircon-S has high selectivity and show less gassing and foaming, longer pot life and higher gloss than dibutyl tin dilaurate (DBTL). It exhibits synergistic effect with zinc and bismuth based catalysts and it supports NCO/OH reactions.
EGECat 8-S is a combination of Bi/Zinc carboxylates. It presents a good balance between efficient croos-linking, tack-free surface, less gas bubles, fewer pin-holes higher gloss and longer pot life.
EGE Kimya has the technical capability and know how to produce individual and combined catalyst systems for the performance profiles such as different pot-life and curing time according to customer requirements.
