Plasticizer Product Profile
Product Description
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.
In vinyl plastisols and organosols, Santicizer® 261 provides relatively low initial viscosity and adequate viscosity stability. It offers fast fusion at normal temperatures, low volatility and permanence in finished vinyl products.
In calendering and extrusions, Santicizer® 261 combines the efficiency of Monomeric Esters with permanence approaching that of low molecular weight polymerics, and offers the excellent processing characteristics of the Benzyl Phthalate type plasticizers. With Santicizer® 261, vinyl compounders can obtain oil, kerosene and gasoline resistance that is better than that obtainable with low molecular weight polymerics or high molecular weight monomerics.
In vinyl foams, Santicizer® 261 provides a good combination of fusion and rheology properties that produce excellent cell structure. Its low volatility helps maintain a permanent, dimensionally stable foam.
