UNIPLEX 400
(POLYPROPYLENE GLYCOL DIBENZOATE)
CAS NO. 72245-46-6
Uniplex 400 is a low volatility, moderately solvating plasticizer. The Uniplex 400 plasticizer is
an efficient, cost/performance alternative to higher alkyl benzyl phthalate plasticizers.
Uniplex 400 is particularly useful in premium sealant applications. The low volatility characteristics are of particular interest to formulators of polysulfide and poly urethane sealants.
Uniplex 400 is also useful in aqueous emulsion systems such as caulks and polyvinyl acetate adhesives. Uniplex 400 may be used to formulate adhesives that need to provide good adhesion between porous and polyolefin surfaces. In caulk formulations, the same excellent performance of other benzoate plasticizers can be expected in addition to providing lower volatility.
Uniplex 400 is an excellent plasticizer for acrylic coatings and acrylic foam coatings. Uniplex 400 in acrylic foam is more effective than higher alkyl benzyl phthalates and tends to volatilize less than those low volatility type phthalates.
