Busan11M1 -Multi Functional Paint Addtive Pigment
Busan11M1 -Multi Functional Paint Additive Pigment
Busan 11-M1 is the commercial form of barium metaborate mono hydrate.
The product is a multifunctional pigment manufactured using a unique process to provide quality performance for the coatings customer.
Busan 11-M1 is 90% active calculated as BaB2O4¢H2O.
Busan 11-M1 is manufactured by Buckman Laboratories, USA and the only EPA registered barium metaborate on the market today.
Busan 11-M1 performs well as a flame retardant in both solvent- and water-base coatings containing a halogen donor, such as chlorinated paraffin. Busan 11-M1 can replace 100% of the antimony trioxide present in most formulations. In certain systems the two can function synergistically. Use levels of 2.0â€œ9.0% for flame retardancy are recommended but will vary depending on the resin used and the halogen donor.
Corrosion/early rust inhibition
Use levels of Busan 11-M1, when used as a corrosion inhibitor, are dependent upon the formulation and performance required. For Industrial, solvent-based coatings, use levels of 2.0â€œ10.0% based on total formula weight are suggested. Use levels of 4.5â€œ9.0% based on the total formula weight are recommended for latex paints. Use levels below 4.5% of total formula weight provide excellent flash- and early-rust inhibition only. Busan 11-M1 is not a vapor-phase inhibitor and will require tipping the can to coat the lid and upper surface of the metal can to ensure protection.
Busan 11-M1 has performed well as a package preservative in latex paints when used at levels of 0.3â€œ0.5% on formula weight. Busan 11-M1 has been reported to Inactivate enzymes. Buckman recommends the formulator conduct ladder studies to determine the optimum use levels in the formulations.
Tannin stain blocking
Busan 11-M1 can be used as a tannin stain blocking agent in latex- and solvent based primers and topcoats. Use levels of 0.251.0% based on total formula weight are recommended for this application. Use alkyd modifier to provide additional wetting. This will be beneficial when formulating latex primers and stains.
Busan 11-M1 provides protection from mold in latex systems when used at levels of 4.513.3% based on total formula weight. Higher use levels are required to enable mold resistance for oil- and alkyd-based coatings, because oil- and alkyd-based coatings provide an excellent food source for mold. Use levels of 8â€œ10% based on total formula.
Weight are recommended. Busan 11-M1 is inorganic. Therefore, leaching from dry paint film is minimized versus competitive organic fungicides.
