Saytex RB-7980 flame retardant is a blend of Saytex RB-79 flame retardant, polyol and a liquid phosphate ester. The mixture of the diester/ether diol of tetrabromophthalic anhydride and phosphate results in a lower viscosity liquid than neat RB-79 flame retardant. Key customer advantages are improved processing and storage characteristics. Lower viscosity at room temperature eliminates the need for heated, insulated storage tanks and drum heating facilities. - Reactive diol for rigid polyurethane foam - Urethane elastomers and coatings |
