Aluminum Paste Storage Guidness

Zhangqiu Metallic Pigment Co., Ltd is a professional metallic pigment manufacturer with 33 years experience.Below are some guidness of aluminum paste storage for your reference.

- Please store aluminum paste on a floor surface with a structure that is capable of preventing intrusion or penetration of water.

- Keep away from direct sunlight, rainwater, and excessive dampness. Store indoors in sealed containers, at no more than 40°C and preferably at 15°C–25°C. For special leafing grades which are subject to stearic acid separation, storage indoors 15 °C–45°C is preferable.

- For leafing grades, in the event of stearic acid separation (apparent as whitish powder or grain) heat the aluminum paste to 30 °C–45°C in its container without exposure to any direct flame or ignition source and then mix well to ensure a uniform dispersion before use. In such cases, particular caution is necessary in opening any container due to the possibility of solvent vapor formation as a result of the heating.

- In the event that bulging occurs in any container during storage due to abnormal internal pressure, before opening the container slowly relieve the internal pressure by opening the vent screw in the container lid if present or by gradually opening the lid clamp while applying downward force on the lid to hold it in place and prevent its violent release. Special caution is necessary in such cases to ensure that the working area is well ventilated and completely free of any ignition sources, because of a high probability of hydrogen gas being present in the container.

- If separation of the solvent and aluminium flakes occurs as an effect of vibration during transport or certain storage conditions, thoroughly mix the aluminum paste to obtain a uniform dispersion before use. Such separation generally does not involve any problem in the quality or performance.

- Please seal containers when not using aluminum paste in order to prevent it from being mixed with reactive substances which may result in alterations to the paste or transformation of the paste into a more dangerous state.
