Adhesion promoter (transparent)
Designation:
  Adhesion promoter -ALO 822 000 10- (transparent)
Issued 06/2011
Product description
This transparent adhesion promoter is a versatile single-pack adhesion promoter for all plastic parts commonly found on vehicle exteriors.
This adhesion promoter is characterised by its excellent adhesion, high elasticity and easy application.
Technical data sheet
Substrate
Suitable substrates:
All plastic parts commonly found on vehicle exteriors.
  PP, EPDM, ABS, PC, PPO, PA, R-TPU, PBTP, PVC.
  PUR, PUR flexible foam.
  UP-GF (fibreglass).
   
Substrate pre-treatment:
The substrate must be free of release agents.
Before cleaning plastic parts, temper them for 60 minutes at +60 °C to “sweat out” the release agents.
–  Clean with anti-static plastic cleaner -LVM 001 001 A2- or with the milder slow-drying silicone remover -LVM 020 100 A5-.
  Note
  •   The effort required for the necessary cleaning depends on the type and quantity of the release agent used. It is recommended to use an emery pad to help in cleaning.
  •   Let the thinner evaporate completely (e.g. air-dry overnight at ambient temperature or for 30-40 minutes at +60 °C).
 

Priming plastic materials

–  Before priming, clean lightly once more with anti-static plastic cleaner -LVM 001 001 A2- or slow-drying silicone remover -LVM 020 100 A5- (with anti-static effect).

Application
Thinner:
–  Do not add any thinner!
Method of application: “spray”.
 

Priming plastic materials

–  Application viscosity 4 mm, +20 °C, DIN 53211
  Note
Do not add any thinner! The viscosity as supplied is identical to the application viscosity.
Application viscosity 4 mm, gravity-feed spray gun “compliant” and “HVLP”:
DIN 4 mm: 11 seconds
 

Priming plastic materials

–  Adjust spray nozzle following manufacturer's instructions to 1.2-1.4 mm for “compliancy”.
–  Adjust spray nozzle following manufacturer's instructions to 1.3-1.5 mm for “HVLP”.
–  Adjust spray pressure following manufacturer's instructions to 2.0-2.5 bar for “compliancy”.
–  Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.
 

Priming plastic materials

–  One full coat is 1-2 µm.

Recoating
 

Priming plastic materials

After flash-off period at +20 °C, may be resprayed with 2-pack HS surfacer elasticized with elastic additive -ALZ 011 001-.
It can then be overpainted with:
  Waterborne base coat and 2-pack HS clear coat
  2-pack HS top coat
