Primary Chemistry:
Phenothiazine (PTZ)
ALLESSAN® Protacryl B15 is WeylChem International’s phenothiazine (PTZ) polymerization inhibitor product offered in solution. This inhibitor functions as a free radical scavenger that optimizes reaction yields and increases the stability of acrylic monomers, derivatives, and chemical intermediate manufacturing. ALLESSAN® Protacryl B15’s ready-mixed solution formation offers the shortstopping of vinyl monomer polymerization, improving yield and helping stop runaway reactions.
Low yields or purity of monomers, derivatives, and intermediates
