The products having
hygroscopicrty stored in hermetic container have the stability.Please keep
away from light and wet.It's color will change when heated and dissolves in
allohol¡¢ketone and avomatic hydrocarbon.
MOCA is curing agent of casting model polyurethen wear-resisting rubber
polyucathen clastomer classified as the scope of half common rubber is one
of the specific rubber developing in the near future.It has excellent wear
sising ability 1.5-10time as much as natural rubber .The products still have
good elasticity and clongation under the high intcnsity(first to forth as
much as rubber)and hardness,meantime have goood buffering ability,oil-resisting.ozone-resisting,ageing-reststing,radiation-resisting,low
temperature-resisting and good insulating ability.
It is extensively applied to machine building industry concluding engineering
industry,cars and planes making industry.mining industry,sports facilities(plastic
cement track and plastic cement floor)and kinds of light industry and so on.It
is still used to connecting agent of polyurethen paint and binder solidify
agent of epoxy resin and to make electronic-resistant prodeucts.
