Application Conditions For Applying Sur-Prep® AP-1 To Conventional Paint Systems and Notes About Conventional Paint Systems

Application Conditions For Conventional Paint Systems

Sur-Prep® AP-1 should be applied when application temperatures are between 65°F and 90°F (18°C and 32°C) with a relative humidity of less than 70%.

The table below shows the topcoats cured between 65°F and 90°F (10°C and 32°C) that can be chemically reactivated with Sur-Prep® AP-1.

Application Conditions for Conventional Paint Systems Notes

Note 1: Previously applied topcoat shall be overcoated within 72 hours after its application.
Note 2: The volume of TR-112 thinner used shall not exceed one part of TR-112 to four parts of TR-109.
Note 3: Applicable to Desothane HS CA 8000 series only.
Note 4: Applicable to Eclipse ECL-G series only.
Note 5: Application of Sur-Prep® AP-1 over CA 8000 Clear may result in poor adhesion of the subsequent topcoat (Color or Clear).
Note 6: Application of Sur-Prep® AP-1 between Eclipse (Color or Clear) topcoat and subsequently applied Eclipse Clear topcoat may result in hazing appearance issues.  No appearance defects, such as hazing, occur when Aerodur 3002 clearcoat is applied over Sur-Prep® AP-1.
Note 7: Once applied, the surface coated with Sur-Prep® AP-1 shall not be touched or disturbed prior to application of any subsequent coating.

The table below shows the topcoats cured above 90°F (32°C) that can be chemically reactivated with Sur-Prep® AP-1.
