Product Description
Bluesil Primaire PM 811 A is a 2K adhesion promoter primer (component A) of the Bluesil PM 811 A+B series — for demanding Bluesil bonding applications with an activated 2K primer system.
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 811 A is tailored to specific applications—the most important properties and areas of use are listed below.
Bluesil Primaire PM 811 A is the activator component A of the PM 811 A+B 2K primer system — it is mixed with component B and applied to the substrate. Proven in demanding industrial bonding applications.

Frequently asked questions about Primer PM 811 A
Practical application and design questions — answered by SILITECH.
Bluesil Primaire PM 811 A: 2K adhesion promoter primer (component A) of the Bluesil PM 811 A+B series — for demanding Bluesil bonds with an activated 2K primer system. Main applications: Demanding Bluesil bonds, specialty substrates, industrial OEMs.
First prepare the substrate clean, grease-free and dry (degrease with acetone, sand if necessary). Apply the primer thinly and evenly with a brush or by dipping. 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 any inhibitors.
Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
