Method of Application

• Air spray

Note:

Adequate ventilation must be maintained during application and curing (please refer to Information Sheets 1433 and 1434 available on request).

In exceptional cases SigmaCover 555 may be applied at lower substrate temperatures (down to -15C (5F)) provided that the surfaceis free from ice and other contamination. In such cases special care must be taken to avoid thick film application as this may lead to checking/crazing or solvent entrapment. It should be clear that application at lower temperatures will require additional thinning to obtain application viscosity, however this will affect the sag resistance of the applied coating and can induce solvent retention. Optimal curing and designed product properties will only be achieved when minimum required substrate temperature is reached.
