PAINT SPECIFICATION NO. 25 BCS Zinc Oxide, Alkyd, Linseed Oil Primer for Use Over Blast Cleaned Steel Type I and Type II spreading rates can be significantly lower. On a calculated basis, the VOC content is 220 g/L (1.9 lb/gal).
1. Scope 1.1 This specification covers a French process zinc oxide, raw linseed oil and alkyd primer suitable for use over blast cleaned steel.
3. Referenced Standards
1.2 This is an alkyd/linseed oil primer containing 30% more alkyd resin than SSPC Paint 25. It is not recommended for hand cleaned steel.
3.1 The latest issue, revision, or amendment of the referenced standards in effect on the date of invitation to bid shall govern, unless otherwise specified. Standards marked with an asterisk (*) are referenced only in the Notes, which are not requirements of this specification.
1.3 This primer is suitable for exposures in Environmental Zones 1A (interior, normally dry) and 1B (exterior, normally dry), and is intended for brush, roller, or spray application over steel surfaces prepared in accordance with SSPC-SP 6/NACE No. 3, “Commercial Blast Cleaning,” or SSPC-SP 11, “Power Tool Cleaning to Bare Metal,” or better. (See Note 9.6.) It is suitable as a shop primer, field primer, maintenance primer, or intermediate coat and is to be applied in accordance with SSPC-PA 1, “Shop, Field, and Maintenance Painting of Steel.” If the primed part of the structure is to be exposed to the weather, it should be topcoated as soon as practical.
3.2 If there is a conflict between the requirements of any of the cited referenced standards and this specification, the requirements of this specification shall prevail 3.3 SSPC STANDARDS AND T STANDARDS: * Guide 7

2. Description 2.1 This specification contains requirements to ensure performance that is comparable to that customarily expected from paints containing lead and chromate pigments. It has fair wetting ability, about 18 hours drying time and good resistance to weathering before field coating. The wetting ability of this primer is the result of one third of the binder being raw linseed oil. Type II has a lower percentage of volatile organic compounds (VOC) thanType I. The reduced VOC content of Type II was achieved by replacing some of the mineral spirits with high flash naphtha and by making other minor composition changes. Details of the compositions are given in Table 1 for Type I and in Table 2 for Type II.
3.4 ASTM INTERNATIONAL STANDARDS:
2.2 The Type I primer contains approximately 65% by volume of nonvolatile film forming solids (pigment and binder). The theoretical spreading rate for a 50 micrometer (2.0 mil) dry film thickness is 12.8 m2/L (520 ft2/U.S. Gallon). Actual spreading rates can be significantly lower. On a calculated basis, the VOC content is 270 grams per liter (2.3 lb/gal).

6.4 PACKAGING: Material shall be packaged and labeled in accordance with the requirements of ASTM D 3951 unless otherwise specified. 6.4 DIRECTIONS FOR USE: The following directions for use shall be supplied with each container of paint:
7. Inspection 7.1 All materials (coatings) supplied under this specification are subject to timely inspection by the purchaser or his authorized representative. The purchaser shall have the right to reject any materials supplied which are found to be defective under this specification. (See Note 9.1.) In case of dispute, unless otherwise specified, the arbitration or settlement procedure established in the procurement documents shall be followed. If no arbitration or settlement procedure is established, then a procedure mutually agreeable to the purchaser and material supplier shall be used.
Directions for Use of Zinc Oxide, Alkyd, Linseed Oil Primer for Use Over Hand Cleaned Steel This paint is intended for use as a primer over steel surfaces cleaned at least to SSPC-SP 6, “Commercial Blast Cleaning,” or to SSPC-SP 11, “Power Tool Cleaning to Bare Metal” in atmospheric exposure. The surfaces shall be free of all visible oil, grease, dirt, dust, mill scale, rust and paint. Mix paint thoroughly before use. If the pigment has settled, pour off most of the liquid. Thoroughly mix the pigment with the remaining liquid, taking care to scrape all the pigment off the bottom of the can. Gradually add the poured-off liquid and mix thoroughly. Mixing may be made easier by transferring the contents to a larger container or by pouring the paint to and from another container. Examine bottom of container for unmixed pigment. Screen paint before applying. The thinning of paint may change the VOC class. For roller, brush, or airless spray application, no thinning should be necessary. A minimum amount of thinning may be necessary for conventional air spray. Apply by brush or spray to the specified film thickness or, if none is specified, to at least 50 micrometers (2 mils) dry. The surface to be painted shall be dry; the surface temperature shall be at least 3 C° (5 F°) above the dew point and the temperature
7.2 Samples of paints may be requested by the purchaser and shall be supplied upon request along with the manufacturer's name and identification for the materials. Samples may be requested at the time the purchase order is placed or may be taken from unopened containers at the job site. 7.3 Unless otherwise specified, the sampling shall be in accordance with ASTM D 3925.

6.4 PACKAGING: Material shall be packaged and labeled in accordance with the requirements of ASTM D 3951 unless otherwise specified. 6.4 DIRECTIONS FOR USE: The following directions for use shall be supplied with each container of paint:
7. Inspection 7.1 All materials (coatings) supplied under this specification are subject to timely inspection by the purchaser or his authorized representative. The purchaser shall have the right to reject any materials supplied which are found to be defective under this specification. (See Note 9.1.) In case of dispute, unless otherwise specified, the arbitration or settlement procedure established in the procurement documents shall be followed. If no arbitration or settlement procedure is established, then a procedure mutually agreeable to the purchaser and material supplier shall be used.
Directions for Use of Zinc Oxide, Alkyd, Linseed Oil Primer for Use Over Hand Cleaned Steel This paint is intended for use as a primer over steel surfaces cleaned at least to SSPC-SP 6, “Commercial Blast Cleaning,” or to SSPC-SP 11, “Power Tool Cleaning to Bare Metal” in atmospheric exposure. The surfaces shall be free of all visible oil, grease, dirt, dust, mill scale, rust and paint. Mix paint thoroughly before use. If the pigment has settled, pour off most of the liquid. Thoroughly mix the pigment with the remaining liquid, taking care to scrape all the pigment off the bottom of the can. Gradually add the poured-off liquid and mix thoroughly. Mixing may be made easier by transferring the contents to a larger container or by pouring the paint to and from another container. Examine bottom of container for unmixed pigment. Screen paint before applying. The thinning of paint may change the VOC class. For roller, brush, or airless spray application, no thinning should be necessary. A minimum amount of thinning may be necessary for conventional air spray. Apply by brush or spray to the specified film thickness or, if none is specified, to at least 50 micrometers (2 mils) dry. The surface to be painted shall be dry; the surface temperature shall be at least 3 C° (5 F°) above the dew point and the temperature
7.2 Samples of paints may be requested by the purchaser and shall be supplied upon request along with the manufacturer's name and identification for the materials. Samples may be requested at the time the purchase order is placed or may be taken from unopened containers at the job site. 7.3 Unless otherwise specified, the sampling shall be in accordance with ASTM D 3925.
