HOW TO SPECIFY ANODIZED AND PAINTED FINISHES FOR ARCHITECTURE.
SAFINISH
A Designation System For Specifying Aluminum Finishes

Southern Aluminum Finishing Company (SAF), long recognized as an industry leader, has developed the "SAFINISH Designation System" for specifying exterior finishes used on architectural aluminum building products.

When architects specify SAFINISH, the resulting finish has the longest expected lifetime of any available for aluminum. SAFINISH coatings are available only on aluminum, because aluminum is the only metal with the longevity and resistance to corrosion equal to the quality implied by the SAFINISH designation. SAF recommends SAFINISH for long-term exterior use. Ask about our five and 20 year limited warranties for SAFINISH coatings.

Specify with Confidence...
SAF has been finishing aluminum for the construction industry since 1946. During these 60+ years, we estimate that we have processed over one billion square feet of aluminum used on thousands of projects worldwide. This unequaled experience in finishing aluminum allows us the unique position of being able to give you an objective selection of the most suitable finish for your application. And only the most durable finishes qualify for the SAFINISH designation.

Specify with Ease...
For many, specifying aluminum finishes is a difficult task, requiring references to specifications from many unrelated trade associations. Architects find the plethora of aluminum finishing specifications confusing at best. SAFINISH Designation System simplifies the specifying process, while maintaining a quality of finish suitable for commercial properties. For detailed information about recommended applications of SAFINISH coatings see SAF's Internet home page.

Specify for reputation...
Specifiers design their buildings to last a very long time. SAF designs their finishes to last equally as well and we stand behind our products. It makes no sense to apply an inferior aluminum finish to cut costs: aluminum finishing is typically less than 1% of a project's cost, but can be 100% of its appearance.

ANODIZING GUIDE SPECIFICATION
Anodic Finish on exposed aluminum components, (** denotes choice, Use Designation System Chart below for selections to fill in the blanks.)

1.	Type: All exposed aluminum shall be given caustic etch followed by an Architectural Class *(I or II)* anodic coating with color conforming to Aluminum Association Designation _______. The color shall be ___________ and shall meet standards set forth by AAMA 611.
2.	Designation: Southern Aluminum Finishing Co., Inc., SAFINISH "SAF____". (e.g. SAF 215 is Class I Clear)
3.	Appearance: coating shall be continuous, uniform in appearance, and free from scratches and other blemishes.
4.	Color variation: No more than 5E (CMC) when measured in accordance with AATCC 173-1989.

NOTES:

1.	SAFINISH coatings are recommended for long-term exterior use. Ask about our 5 and 20 year limited warranties for SAFINISH coatings.
2.	Limitations: Class II dyed finishes (SAF 804) are not exterior lightfast.
3.	Spectrocolorimeter conditions: integrating sphere specular included, 10 degree standard observer, D-65 Illuminant, CMC Ratio 1.50:1.00.

PVDF SPRAY PAINTED FINISH GUIDE SPECIFICATION
A. Finish on exposed aluminum components:

	1.	Type: two-coat, shop applied, high performance, 70% Polyvinylidene Fluoride (PVDF) coating based on Arkema Inc, Kynar 500 or Solvay Solexis Hylar 5000 resin, formulated by a licensed manufacturer and applied by manufacturer's approved applicator, to meet AAMA 2605. Applicator is to pretreat the aluminum with solutions to remove organic and inorganic surface soils, remove residual oxides, followed by a chrome phosphate conversion coating to which organic coatings will firmly adhere.
	2.	Designation: Southern Aluminum Finishing Co, Inc. SAFINISH, SAF 266.
	3.	Color: Standard or Custom color as selected by architect.
	4.	Touch-up paint: Provide matching touch-up paint for minor touch-up of small scratches, abrasions, and fasteners. Paint shall be applied with an artist brush and never spray applied.
	5.	Color variation: No more than 2E (CMC) when measured in accordance with AATCC 173-1989.
