Glasurit® Air-Drying Additive
523-65
 
G / Z

Application:

 

Additive for accelerated air drying of Glasurit® 2 component standard VOC clearcoats on vertical and horizontal surfaces.

Using 523-65 will allow for a dust-free surface more quickly. Sandability, polishability and readiness for assembly will be significantly improved. 523-65 is particularly suited for bodyshops who want to save energy and dry the clearcoat at a panel temperature below 60°C. 523-65 can help to reduce the occupation times of the combi-booth and drying oven. 523-65 is particularly suited for small repairs.

Properties:

 

Shorter drying time at room temperature

Improved surface drying, curing and polishability

 

Remarks:

 

Use Glasurit 523-65 Air-Drying Additive at room temperature > 20°C only.

Ambient temperature and film build can greatly affect the drying behavior.

523-65 is intended for use only in 923- 610, -625, -630.

523-65 will reduce the potlife.
