Santicizer 261 Plasticizer is a monomeric plasticizer that offers good performance, yet still retains the easy processing features of monomeric plasticizers. It finds application in Polyurethane and Polysulfide caulks and sealants, film and sheeting, coated fabrics, plastisols, organosols, vinyl foams and acrylic lacquers.
In polyurethane, Santicizer 261 has excellent compatibility, provides good viscosity control and, due to its low volatility, excellent permanence. High filler loadings are possible because of the excellent wet-out characteristics of Santicizer 261.
In acrylic coatings, Santicizer 261 imparts excellent durability, anti-fogging properties, better adhesion to metal undercoats, improved weatherability and good solvent-craze resistance. It imparts excellent gloss, resists water spotting, provides good flow characteristics and flexibility without brittleness for a long, handsome coating life. The low volatility and greater permanence makes it the preferred modifier for acrylic coatings that must have a long service life and/or must endure under high-temperature exposure. |
