Tech Data

Product Description: Blastox^® is a granular, complex calcium silicate-based blasting abrasive additive.

Use: Typically used at a 15 percent weight ratio for stabilizing lead in lead-based paint blast removal operations, producing a non-hazardous waste suitable for disposal in a subtitle D landfill. Use is compatible with standard dry or wet blast equipment.

Chemical Reactions: Blastox^® produces lead silicates through chemical conversion of the lead in the paint. It is intended solely as a lead stabilizing additive, reducing leachable lead in untreated spent abrasive wastes from up to100 mg/1 to less than 5.0 mg/1 (RCRA limit for lead) according to TCLP.

Restrictions: Material must be kept dry until preparations are made for field application. Wet or otherwise contaminated Blastox^® does not carry a performance guarantee. For dry blasting operations, moisture separators are required and air dryers are recommend. Blastox^® is designed with cementious properties and may solidify in equipment, on substrates and around general work areas upon extended exposure to moisture. Care should be taken to avoid these situations or additional cleaning measures may be required.

Application Techniques: For dry blasting lead painted steel , six (6) to eight (8) pounds of a 15 percent weight ratio blended abrasive must be used per square foot of paint removed for adequate stabilization. For blasting lead painted wood substrates or for blast operation using less than six (6) pounds per square foot of paint removed, contact TDJ Group's Technical Service department for specific recommendations.
