Guangdong
Guyan Electronic Material Company
TECHNICAL DATA SHEET(TDS)
GY100A-U
DESCRIPTION
GY
100A-U is intended for use as
a latent accelerator for the dicyandiamide
cure of epoxy resins. It belong
to an aromatic substituted urea
compound without halogen element.
The addition of GY 100A-U to epoxy/dicyandiamide
formulations reduces the time
and/or temperature required to
cure these shelf stable one part
products. GY 100A-U Provides the
greatest degree of acceleration
to epoxy/dicyandiamide formulations.
Suggested use levels of GY 100A-U
are ¡Ü5 phr. Curing can be accomplished
in about 36 minutes at 100¡æ and
in less than 4 minutes at temperatures¡Ý140¡æ.Cure
times are dependent on the composition
of the formulated product and
the particular end application.
Room temperature(25¡æ) shelf lives(time
to double viscosity)of >3 months
can be obtained when¡Ü 1 phr is
used with epoxy/ dicyandiamide.
Some of the factors can effect
shelf life including formulation
ingredients and production process.
Insoluble ingredients to GY 100A-U
is suitable for prolonging shelf
lives. The most significant advantage
of GY 100A-U is rapid cure as
a latent accelerator. The cured
product is shiny, yellowish and
semitransparent.
APPLICATIONS
As a latent accelerator in the
dicyandiamide cure of
epoxy resins used in:
Adhesives
Coatings(liquid
or powder)
Encapsulations
Reinforcements
prepreg

HEALTH£¦SAFETY PRECAUTIONS
GY
100A-U is a micro powder. It will
cause respiratory irritation with
prolonged dust inhalation. It¡¯s
necessary to wear goggle and mask
in the process of production and
transportation. The dust explosion
may be caused if it is dispersed
into the air.
