Detailed Product Description:
Touch-N-Prep Alodine 871 is a no-rinse non-hexavalent chromium
conversion coating chemical in a magic marker-type applicator for use
on aluminum, and its alloys for industrial maintenance and treatment
applications.
Touch-N-Prep Alodine 871 effectively phosphates most metals including
aluminum, ferrous and galvanized substrates. It doesn’t require rinsing,
and can be air-dried or force-dried with something as simple as a hair
dryer or an infra-red lamp.
Key Features:
- Ideal for touch-up and field repair on aircraft—convenient, fast, reduced labor costs.
- Full 2-year shelf life (compared to 1 year for other Alodine Compounds).
- No rinsing required.
- Usually dries in 5 minutes or less.
- Meets Mil Spec requirements for aluminum conversion coating.
- Cost Effective—though initially expensive, when total costs are considered significant savings can be realized.
History:
First developed by Hughes, the applicator was originally filled with
Alodine 1200 which still required water rinsing. Henkel bought the rights
to the pen applicator for which they subsequently developed this unique
no-rinse Alodine formulation.
The coating produced is significantly different from a typical conversion
coating and was specifically developed for this type of dry-in-place application.
Specification & Certifications:
Alodine® 871 methods and properties are applicable to the requirements
of Mil-C-5541-F (Now AMS-C-5541) and AMS-A-2473. The composition
conforms to MIL-DTL-81706B and is listed on QPL-81706. The resulting
coating meets both Class 1A and Class 3. Note that these specifications
approve this product for aluminum alloys only.
Application Notes:
The high density acrylic tip of the Touch-N-Prep applicator can be modified
With a single edge razor blade to form any shape. The application method
controls the amount of coating applied to the surface.
Pre-warm the surface (with a blow dryer, for example) and allow the heated
Metal to flash off the coating chemicals. This also gives the most pleasing
appearance.
Surface Preparation:
Aluminum surfaces must be chemically clean—they produce a water-break-free
surface. The preferred cleaning method is to use a Bear-Tex or ScotchBrite Pad
wet with Alumiprep 33 or Metalprep 79 to chemically abrade the surface and
remove all traces of surface oxides. Please refer to Technical Process Bulletin
for further cleaning details.
Precautions:
As with most Alodine compounds, contains chromium and fluoride compounds.
Avoid eye and skin contact. See MSDS available below.
Packaging/Size:
Comes packed in a marking pen type applicator.
