8. Environmental conditions
The coating temperature range is 10-30℃, the relative humidity is
below 85%, the surface temperature of the substrate is more than 3℃
higher than the dew point, and the temperature and humidity should
be measured near the substrate. When the surface temperature of the
substrate is higher than 40℃, it is recommended not to carry out
painting construction. Rain, snow, sand and other bad weather, can
not be painted.
9. Packaging specification
A=20kg/drum B=20kg/drum
10. Storage
This product should be stored in a cool, dry, ventilated indoor
warehouse, storage period of half a year.
11. Statement
1) The protective effect of any coating depends to a large extent
on the coating construction, surface treatment, film thickness and
other construction factors will directly affect the service life of
the coating, the user should meet the agreed construction
conditions when using this product.
2) The data in this manual are theoretical values or accumulated
through experiments. With the continuous improvement of the
product, some data may change without prior notice.
3) When the company's technicians are not at the painting site, the
company is only responsible for the quality of the coating product
itself.
