Instructions

When using BG-2577, solvents such as propylene glycol methyl ether acetate (PMA) and propylene glycol diacetate (PGDA) can be added for dilution. It is recommended to use ammonia ester grade solvents (with a water content of less than 0.05%) for dilution, with a solid content of no less than 40%. Conduct specific experiments before use and Stability testing. The mixture added with BG-2600-100 must be used during the activation period.

storage

The product should be stored in a sealed container to avoid freezing and high temperatures. It is recommended to keep the sealed packaging intact at a storage temperature of 5-35 ℃. The shelf life of the product is twelve months from the production date. After the shelf life is exceeded, it is recommended to conduct a performance evaluation before use.

The product is very sensitive to moisture and reacts with water to produce gases such as carbon dioxide and urea, which can cause container pressure to rise and pose a danger. After opening the packaging, it is recommended to use it as soon as possible.
