Apply at 15 °C to 30 °C. Do not apply to surfaces above 66 °C.

It cures under water and will adhere to most damp surfaces. It can be applied to wet surfaces, but bond strength will be lower.

The cure time of 10 minutes is at 25 °C. Henkel's strength figures are measured after one week at 23 °C.

Storage and handling

Store unopened in a dry place. The optimal storage temperature is 8 °C to 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.

Limits and safety

Henkel lists non-structural defects in castings among its applications. The data sheet states no cured service temperature, so check with Henkel before using it where heat is a factor. Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidisers. Read the safety data sheet before use.
