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.
