Non-pigmented, solvent-based primer for metals Sika® Primer-210 is a solvent-based colourless to slightly yellow primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives. Sika® Primer-210 is specifically formulated for the treatment of bond faces prior to application of Sika’s 1-component Polyurethanes. |
Usage Sika® Primer-210 is used to improve adhesion on many metals such as aluminum, steel and non-ferrous metals. The primer might also be used to enhance the adhesion of Sikasil® sealants and adhesives. Seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-210 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility. |

Technical Information IMPORTANT NOTE Sika® Primer-210 is a moisture reactive system. In order to maintain product quality it is important to reseal the container with the inner plastic liner immediately after use. Once the surface pre-treatment operation is completed, the cap has to be screwed on. Dispose of product approx. one month after opening if used frequently or after two months in case of infrequent use. If gelling, separation or a significant increase in viscosity is noted, discard the primer immediately. Never dilute or mix this product with any other substances. If used on transparent or translucent substrates such as plastics, etc., an adequate UV protection is mandatory. |
Application Information METHOD OF APPLICATION Surfaces must be clean, dry and free from grease, oil, dust and contaminants. Adhesion on substrates might be improved by adding and/or combining pre-treatment processes such as scuffing, cleaning and activating prior the primer application. Primer Application Apply a thin but covering coat of Sika® Primer-210 with a brush, felt, clean lint-free cloth or foam applicator. Sika® Primer-210 exhibits a thermo-plastic behavior up to 3 days after application, therefore higher temperature or early stress to the bond line have to be avoided. Ideal application and surface temperature is between 15 °C and 25 °C. Sika® Primer-210 has to be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Consumption and method of application depend on the specific nature of the substrates. Tightly reseal container immediately after each use. |
