Bluesil Primer PM 820 is a high-performance adhesion promoter primer for bonding silicone to polar plastics (polyamide, polyester, ABS, polypropylene) and composite materials.
Bluesil adhesion promoter primers prepare critical substrates (metal, plastic, glass, polyester) for bonding with silicone elastomers, resulting in significantly higher shear strength than untreated substrates. Primer PM 820 is tailored to specific applications—the most important properties and areas of use are listed below.
Bluesil Primer PM 820 is a specialized adhesion promoter for polar engineering plastics such as polyamide, polyester, ABS, and polypropylene—substrates that are otherwise difficult to bond with silicone. It is proven effective for bonding composite components with 30% glass fiber content.

Frequently asked questions about Primer PM 820
Practical application and design questions — answered by SILITECH.
Bluesil Primer PM 820: High-performance adhesion promoter primer for bonding silicone to polar plastics (polyamide, polyester, ABS, polypropylene) and composite materials. Main applications: polyamide bonding, polyester components, ABS bonding.
First, prepare the substrate to be clean, grease-free, and dry (degrease with acetone, sand if necessary). Apply the primer thinly and evenly using a brush or dipping method. Allow to dry for at least 30 minutes at 23°C, then apply the silicone (RTV/CAF/Bluesil) to the primed area. For polyaddition silicones, the primer must not contain inhibitors.
Store in the unopened original container in a dry, cool place — typically between +5 and +30 °C, see TDS for exact values. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging — Elkem guarantees the product's specifications only until the date shown.
