AUCAT Series of Anti-hydrolysis Polyurethane Catalysts

AUCAT Series of Eco-friendly Tin Free Anti-hydrolysis Polyurethane Catalysts can be used in all fields of polyurethane, such as foam, coating, leather, elastomer and so on.

Description

Most organic metal catalysts such as bismuth, zinc and tin catalyst commonly used in polyurethane have hydrolysis failure in varying degrees. When premixed into aqueous raw materials, the catalytic activity gradually decreases until it is lost within a few days or even just a few hours. For example, the hydrolysis resistant tin catalyst with special structure has a stable storage period of only more than one month, and ordinary bismuth quickly hydrolyzes and loses catalytic activity within a few hours. As an important functional assistant, the hydrolysis failure of catalyst not only leads to inconvenient use, but also greatly hinders the innovation and development of polyurethane in some fields.

After years of unremitting efforts, Yunrun has pioneered the development of AUCAT series of hydrolysis resistant eco-friendly organometallic catalysts, which can be used in all fields of polyurethane, such as foam, coating, leather, elastomer and so on. Typical characteristics are as follows:

◆ Hydrolysis resistant. Stable storage in aqueous system, hydrolysis resistance, long-term storage, catalytic activity does not decay.

◆ Targeted catalytic feature. It selectively catalyzes the reaction of hydroxyl and isocyanate, with high strength, no bubbles and high gloss.

◆ Strong gel and high catalytic activity. Substitute for Tin catalyst, be used in all PU fields such as foam, coating, adhesive, PU leather, elastomer, etc. It is especially suitable for foam as strong gelling catalyst.

◆ Eco-friendly and tin free. Meet the needs of toys, shoe materials, clothing, coatings and other export products.

Product TypeProduct ModelCatalytic Features Application Field
Conventional functional typeAUCAT-101101 similar to strong gel bismuth, 201 is similar to organic zinc with long flow time. They can collocate freely, and can meet various  processing requirements such as fast curing, slow curing, slow before and fast after, ect.Various general purpose polyurethane fields, such as coatings, resin synthesis, PUD, elastomer, foam, etc.101 is used for soft foam, eco-friendly and non hydrolysis. It is widely used for foam of toys, clothing, shoes, automobiles, etc.
AUCAT-201
AUCAT-101WIt has good compatibility for water-based system and does not affect the gloss.101W is the main catalyst for strong gelling, 201W is used as the post forming catalyst, and they can collocate freely to meet the requirements of various processes. For water-based coatings, directly added to water-based emulsion for long-term storage without failure. The coating film does not lose gloss.  It resolves the problems of barrel swelling, yellowing, viscosity increase and even curing, which are caused by the present catalysts that can only be added into the isocyanate curing agent component.
AUCAT-201W
AUCAT-1001EIt is not sensitive to moisture and does not foam, and substitutes for mercury, lead and tin catalystUniversal type, mainly used in non foaming CASE field; Stronger gel than 101.
AUCAT-T62It is used as post forming catalyst to accelerate the post curing, which has no effect on the flow time.CASE field, particularly for coating, the curing in winter is faster than Tin catalyst
AUCAT-1301High activity is equivalent to that of tin catalyst and has thermal activity. It is recommended for resin synthesis.Used for synthesis of aliphatic non yellowing resin, such as shoe glue, etc
Heat sensitive functional typeAUCAT-RM301Heat sensitivity, high activity, long flow time, fast curing and forming;The activity at room temperature is low, and the catalytic activity increases geometrically after the thermal mutation point.It can be used for back glue of carpet or artificial lawn, low deformation foam of electronic products, mine screen, etc. it is suitable for the whole PU field. In MDI + Polyester / polyether + BDO system, it has the characteristics of long flow period and fast post curing.
