Frequently Asked Questions about Primer PM 811 B
Practical application and design questions — answered by SILITECH.
Bluesil Primaire PM 811 B: 2K adhesion promoter primer (Component B) of the Bluesil PM 811 A+B series — reactive component, mixed with PM 811 A for the most demanding bonding applications. Main applications: Combine with PM 811 A, special industry, aerospace bonding.
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.
