Difference between Alodine 1200 and Alodine 1132 touch-N-Prep
2004
Dear Sirs,
Can Alodine 1132 touch-N-Prep. be used as an alternate of Alodine
1200. I know that Alodine 1200 is used for aluminum AND its alloy. Does this apply as well for Alodine 1132?
Best Regards,

Approved MIL-DTL-81706
[on DLA]
for Class 1A and Class 3 coatings. Class 3 approval is not listed on the current MIL-DTL-81706A (2/18/2002 or
QPL-81706
[on DLA]-16 (9-28-2001)but it has military approval. You can contact the supplier for a copy of the approval letter (for Class 3). This can be used until these publications are updated. Do not rinse the coating. Let it dry in place.

What is the difference between Alodine 1201 [on eBay or Amazon] and Alodine 1132
Chuck Pinney- Woodland Hills, California
Although these products may be listed in QPL's, it is important to remember that they are trade names for proprietary products and they mean no more and no less than Henkel says they mean, Chuck.
A Thunderbird is a 2-seat sports car, a 4-seat luxury car, a 6-seat family car, or a 2-seat luxury car depending on how Ford Motor Co. decided to use that trademark in a given year; and although Alodine 1201
[on
eBay or
Amazon] hopefully has a more fixed meaning than that I would not rely on a differentiation offered by anyone but Henkel. Good luck.

It is reported that anodizing aluminium alloy reduces its fatigue life (for example: CREE A.M. and WEIDMANN G.W., Effect of anodised coatings on fatigue crack growth rates in aluminium alloy, Journal of Surface Engineering, 1997, vol. 13, no 1, pp. 51-55).
Is there any evidence to suggest that the application of Alodine
(specifically Alodine 1132) has any impact on the fatigue life of aluminium alloys typically used in the aircraft industry?
