8. ATTENTION
Check the Material Safety Data Sheet (MSDS) before using the
product.
Sealant products are not toxic after fully cured, but should avoid
contact with eyes before curing. If contact with eyes, rinse with
plenty of water and consult a doctor. uncured products should be
kept out of contact with children. The product will release small
molecular substances during the curing process, and ventilation
should be paid attention to in the construction and curing areas to
prevent the concentration of small molecular substances from being
too bad for people.
