Ⅸ. Cautions

1. Cautions in use

a)        Part A should be agitated before use to disperse sufficiently the settled filler.

b)       Part B may be crystallized when it is stored at low temperature, in this case, heat it to 40-50℃ until it is completely dissolved.

c)        Weigh both A and B respectively, into specified amounts and mix them uniformly.

 

2. Cautions in handling

a)        Work place should provide a ventilator for performing sufficient ventilation

b)       Protective garments, gloves, goggles are necessary to workers to avoid direct contact of the materials.

c)        In the event of the agent contacting the skin wash it off immediately with warm water and alkali-free soap. Medical treatment is needed if skin is seriously imitated.

d)       Avoid breathing vapors, which can cause respiratory damage.

 

3.Cautions in Storage

a)        Store it at the cool and dark place (preferably between 15℃ and 25℃)

b)       Seal the products to avoid mixing of water into the products.

c)        Keep to the first-in first-out

d)       Once the container is opened, the material should be used as fast as possible, to prevent properties from deterioration by foreign substance and moisture absorption
