Some notes on using Apollo Silicone Sealant A250

When purchasing the Apollo A250, essential information about the product is surely provided on the packaging. Before usage, customers should read and thoroughly understand the necessary details.

Product expiration date and storage conditions

The shelf life of Apollo Silicone is 12 months from the manufacturing date printed on the packaging. After use, the sealant bottle needs to be stored in a way that prevents air from getting inside. Furthermore, the product should be kept at temperatures below 30°C.

Therefore, distributors of the sealant should also take care to keep the product in a dry place below 30°C. For used sealant tubes, customers need to tightly seal the tube mouth to avoid any air getting inside. If air infiltrates, the quality and adhesion capability of the sealant might alter.

Product limitations

Here are some limitations that customers need to understand before using the product:

  • Avoid using the product to bond materials affected by oils, plasticizers, solvents, or incompletely cured rubber pads or linings.

  • Material surfaces might corrode or change color when exposed to acid vapors during the silicone curing process (such as zinc-plated steel, copper, brass, or other metals, concrete surfaces, cement panels, tiles, limestone, quartzite, or high porous stone surfaces, etc.).

  • Sealing waterproof joints on premium facades.

  • In locations where the sealant does not come into contact with air.

  • Porous quartzite and high porous stone surfaces.

  • Joints requiring an elongation greater than +15.

  • Overpainting after curing as paint cannot adhere to silicone.

  • Plastic sheets.
