- Application Method:
Quantify the two Constituents A and B as per blending ratio and
they can be used after being stirred uniformly. A two-time or more
embedment method is recommended for a smooth and bright surface.Thereafter,
the embedded product is placed in the dry and dust-free environment.
When room temperature is lower than 20oC, it would be the best to
pre-heat the Constituent A properly to 40~55oC and it would show
a better performance.
- Attentions:
The two constituents should be quantified strictly per proportion.Either
excessive or insufficient
B constituent will affect the performance of the cured epoxy resin.
Make sure to stir uniformly after the two constituent of A and B
are mixed up, to avoid the negative influence over curing effect.
Long-term storage of Constituent A will lead to a small quantity
of sedimentation.Should stir uniform before use.
Constituent Bmust maintain insulated after use, to avoid negative
influence over curing effect arousing from moisture absorption.
Pay attention to ventilation in the working environment. Avoid the
material from spattering into mouth and eyes at use.
Storage must conform to basic requirements of normal chemicals:
Shade,dry and ventilation.The storage perild is 6 months.
