2-Component SIP

Information 

Use the primer within 8 hours. Apply a thin, even coat to the bonded flanges and remove excess primer. Protect surfaces you have already primed from dirt and soiling. Otherwise, the bonded joint may be defective.

Information 

• Primed surfaces can be stored in the open for a maximum of three days before undergoing further processing. When doing so, make sure that the surfaces are not soiled by the surrounding environment. After standing in the open for more than three days, the primer must be removed and reapplied. For this reason, body parts must be stuck immediately after the primer has been applied  .

8. Check primer application.

   Adhesive flanges are coated evenly with primer:

   result is OK.

   Remove excess primer with a clean, dry cloth.

   A thin, violet-coloured coating of primer is sufficient for the adhesive flanges.

   Adhesive flanges are not evenly coated (droplet formation):

   result is not OK.

   Using wet sandpaper (approx. 200 grit) or a sanding fleece, rub the primer film, which is still damp, around the flange area until an even application of primer is achieved. If an even application of primer is not obtained, the adhesive flange must be completely cleaned, sanded and primed once again.
