Application And Performance:
XYlink311 is equal to Caytue®31 DA. It is a delayed action diamine curative primarily for use
with urethane prepolymers based on TDI (toluene diisocyanate), or
MDI (diphenylmethane diisocyanate) and polyether polyols. It
consists of a complex of methylene dianiline (MDA) and solium
chloride dispersed in dioctyl adipate. It has a very low free MDA
content. At room temperature, it is virtually non-reactive.
However, when heated to 120℃(After catalyst added, it can take the
temperature down to 70-80℃), the salt complex unblocks and the
freed MDA rapidly cures the prepolymer, forming a tough elastomer.
As a liquid with reasonable viscosity, XYlink311 can be mixed with
prepolymers at room temperature, and it is suitable for use with
conventional processing techniques such as: open casting, transfer,
compression or liquid injection molding and rotational casting as
well as other techniques such as dipping that require one pot
systems. In addition, it is uniquely suitable for specialty
applications, which require large surface areas; intricate design,
microwave curing or other situations that require essentially
unlimited work life and stability. The curing properties of
XYlink311 are similar to MOCA. When it mixes with prepolymers
without heated, it will not occur gelatin phenomena, it can be used
in MDI systematic prepolymers.
XYlink311 can be processed satisfactorily with hand mixing or
automatic mixing casting equipment for processing liquid urethane
