Preparation of the removed rearscreen

2. Thoroughly clean the housing for the rearscreen using an air jet and degrease fully with heptane. In the case of sticking operations more than 60 minutes after the sealant has been cut and levelled, the surface of the sealant must be treated using PUR activator and 15 minutes must elapse before the rearscreen is fixed.
3. Position and stick the new seal along the entire perimeter of the rearscreen housing.
4. Remove the adhesive tape from the perimeter of the rearscreen housing.

NOTE: As either the removed rearscreen or a new rearscreen can be refitted, the procedures for preparing both rearscreens are described below.

Preparation of the removed rearscreen

• Check that the rearscreen is not damaged.

1. Using a suitable tool, cut and level the sealant on the rearscreen, so that the thickness is between 0.25 and 1 mm, without scratching the serigraphy. The thickness of the sealant remaining on the rearscreen will act as a support for the new sticking process.
2. Thoroughly clean the housing for sticking the rearscreen using an air jet and degrease fully using heptane.

In the case of sticking operations more than 60 minutes after the sealant has been cut and levelled, the surface of the sealant must be treated with a special PUR activator and 15 minutes must elapse before the rearscreen is fixed.

Preparation of the new rearscreen

• Check that the new rearscreen is not damaged.

1. Degrease the serigraphed area involved in the sticking using heptane.
2. Apply PRIMETER 5100 (green cap) to the degreased surface.

Wait for around 15 minutes before carrying out the next operation to allow the solvent to evaporate.
