Processing
WACKER® PASTE P 12 can be applied using a brush, spatula, or by screen printing. Best results are achieved when a uniform, thin layer is applied to the contact surfaces. Excess paste squeezed out during assembly should be removed.
Storage
The product should be stored in a cool and dry place. The best-before date for each batch is indicated on the label. Storing beyond this date does not necessarily mean the product is unusable. In such cases, the properties required for the intended use should be checked to ensure quality.
