SCOPE
This
specification establishes the priming, painting and topcoat
color requirements for
components in accordance with the customer contract specifications.
This procedure shall be complied with
invoked on appropriate
engineering drawings for the use of aluminum or steel sheet,
plate and shapes (tube, rod, channel, etc.)
1.1
Exceptions
1.1.1
Drawings with Undefined Finish Requirements for Aluminum
On Engineering drawings for fabricated aluminum parts that have no noted
finish requirements, it shall be inferred that MIL-C-5541 Alodine/Irridite
finish and a suitable surface preparation for said finish shall apply. (Ref.
3.1)

GENERAL
REQUIREMENTS
|
|
3.1 |
Surface
Preparation
All material substrate surfaces shall receive proper pre-treatment to ensure
subsequent application of primer/paint to the parent material per the applicable
MIL standard or OEM specifications and/or processes. Typical methods of surface
preparation for steel and/or aluminum include:
• Bead Blast, see A-A-59316 for abrasive materials
• Degreasing solution
• Mechanical Preparation such as sanding/grinding
• Alodine/Irridite per MIL-DTL-5541
Parts shall be cured and dried prior to additional processing
|
|
3.2 |
Primer
and Paint Application
All primer and paint shall be applied to the parent material per the applicable
MIL standard or OEM specifications and/or processes. If a conflict exists between
the primer listed in Table 1 and the corresponding primer identified in the
Top Coat specification listed in Table 1, the Top Coat specification/requirement
takes precedence.
|
3.3 |
Paint
Process and Part Quality
All material built to this specification shall adhere to the paint process
and part quality requirements identified on the purchase order, engineering
drawings and supporting documentation. The in process inspection, rejection
and rework requirements of the appropriate process specification shall be followed,
i.e., MIL-PRF-85285, as identified in Table 1.
The
vendor shall ensure that all material is processed in accordance
with ITW Military GSE IndustriesTIQAM02, Quality Assurance Manual.
|
| 3.4 |
Powder Coating
Powder Coating shall comply with MIL-PRF-24712 with tailoring as follows:
|
|
3.4.1 3.4.2 3.4.3
|
Type X, Polyurethane
(section 1.2.1) Use acceptable industry practice for resin and curing system
(section 3.2) For aluminum applications use MIL-DTL-5541 for surface preparation
with tailoring as follows: 3.4.3.1 Type I or Type II (section 1.2.1),
vendor shall select a type and not mix methods.
3.4.3.2 Class 1A (section 1.2.2)
3.4.3.3 Mechanically damaged areas may be
touched-up. (sections 3.4 and 3.5)
3.4.3.4 No inspection or testing required.
(section 4.1)
|
|
3.4.4 |
For steel application
use Federal Specification TT-C-490 with tailoring as follows: 3.4.4.1 Type II chemical conversion (section
1.2.2)
3.4.4.2 No inspection or testing (section
4.1)
|
|
3.5 |
Vendor shall forward
coating detail sheets and sample coupons for each shipment.
