Hydroxypropyl acrylate is a colorless and transparent liquid with a pungent odor and certain chemical activity. Its storage requires comprehensive consideration of various factors. The specific storage conditions are as follows:

Temperature and Light

Temperature: It should be stored in a cool environment, and the storage temperature is generally recommended to be maintained between -10°C and 25°C. Excessively high temperatures may accelerate the polymerization reaction of hydroxypropyl acrylate, causing product deterioration and affecting its chemical properties and usability.

Light: Direct sunlight should be avoided because exposure to light such as ultraviolet rays may trigger photochemical reactions, promoting the polymerization reaction. Therefore, indoor storage is generally adopted, and shading materials can be installed on the windows of the warehouse to reduce the impact of light on the product.

Container Selection

Material: Sealed containers that meet relevant standards should be used for storage, usually stainless steel containers or plastic containers (such as high-density polyethylene containers). Hydroxypropyl acrylate is corrosive to metals (such as iron), so ordinary iron containers should not be used, while stainless steel containers can better resist its corrosive effect; for plastic containers, it is necessary to ensure that they do not chemically react with hydroxypropyl acrylate, and high-density polyethylene containers are a more suitable choice.

Sealing: The container must have good sealing performance to prevent air from entering. Because hydroxypropyl acrylate is more prone to oxidation and polymerization reactions in the presence of oxygen, a well-sealed container can reduce contact with oxygen and extend the product's shelf life.

Environmental Requirements

Ventilation: The storage area needs to have good ventilation conditions, which can timely discharge the potentially leaked hydroxypropyl acrylate vapor, reduce the concentration of its vapor in the air, avoid reaching the explosion limit, and at the same time help ensure the health of staff in the storage environment and prevent excessive inhalation of harmful vapors.

Keep Away from Ignition Sources and Oxidants: Hydroxypropyl acrylate is flammable and can react violently with strong oxidants. Therefore, the storage warehouse should maintain a sufficient safe distance from ignition sources (such as open flames, electric sparks, etc.), and should not be stored together with oxidants (such as potassium permanganate, hydrogen peroxide, etc.).

Other Precautions

Clear Labeling: The name of "hydroxypropyl acrylate", hazards (such as flammable, harmful, etc.), storage precautions, and other information should be clearly marked on the storage container to facilitate management and identification.

Regular Inspection: Regularly inspect the stored hydroxypropyl acrylate to check whether the container is leaking and whether the product has signs of deterioration (such as color change, precipitation, etc.) to ensure storage safety.
