Ransom & Randolph Ultra-Vest with BANDUST Investment-44 Lb Box

Ransom & Randolph Ultra-Vest with BANDUST is specially formulated to significantly reduce total respirable dust from mixing and quenching silica-based investment — by up to 99% compared to Kerr Satin Cast and 97% compared to regular R&R Ultra-Vest.

BANDUST is not a new type of investment powder. It is a substance added to R&R investment that binds small particles to the investment material, reducing respirable dust at the source. First developed in Europe, Ransom & Randolph has refined its use to deliver a product that dramatically cuts dust without compromising casting performance. The BANDUST safety feature changes nothing about casting results — no adjustment to powder-to-water ratio or any other step in your investment process is required.

Ultra-Vest with BANDUST is an excellent investment for casting in gold, silver, and other alloys that cast at or below 2,200°F (1,204°C). It produces a very smooth surface finish and mixes much like original Ultra-Vest, with only minor changes to set-up time and no meaningful change in dissolving time during quenching or breakout. It is process-friendly and not as instruction-critical as some competing investments, though following mixing instructions consistently yields the best repeatable results. R&R investments are known for consistent batch-to-batch performance.

Notes

Health & Safety Warning: This product contains a blend of crystalline silica. Prolonged inhalation may be harmful. IARC reports sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica (quartz or cristobalite) from occupational sources. Symptoms may not appear until permanent lung damage has occurred. Users should have periodic physical examinations for silica exposure. Work areas should be periodically tested to determine airborne crystalline silica levels relative to OSHA and MSHA standards. Always wear NIOSH-approved respiratory protection for crystalline silica dust when working with this product or when dust exposure is possible. Users must comply with all applicable health and safety regulations for safe handling of crystalline silica. See SDS for complete safety information.

California Prop 65 Warning: This product contains crystalline silica, a chemical known to the State of California to cause cancer.
