PRODUCT DESCRIPTION
Duracet 898 is a flexible self-crosslinking vinyl acrylic copolymer. This copolymer was designed for use as a binderfor nonwovens, bulk builders in textile finishing, as flock adhesives or in any adhesives application requiringexcellent water resistance.
Duracet 898 is stabilized with a cellulosic colloid and also contains carboxyl functionality for additional specificadhesion and compounding versatility.
PHYSICAL PROPERTIES
ADDITIONAL INFORMATION
Dry films are flexible, glossy and clear. The water resistance is excellent if the polymer has been adequatelycured. When immersed in perchlorethylene, the films will exhibit moderate swelling.
Duracet 898 should be thickened with cellulosic thickeners, although polyacrylate thickeners may be used if apot life of less than 12 hours is adequate. Depending on conditions, this emulsion will generally dry and cure infrom 1 to 4 minutes at from 275 to 300°F. If the cure time or temperature is marginal, catalysts such asaluminum chloride (0.5% on solution weight), diammonium acid phosphate (1.0%) or oxalic acid (0.1%) may beused. Water soluble melamine-formaldehyde resins (2% to 10%) will also co-react with this emulsion. The useof catalysts or reactive resins will shorten the useful pot life.
Duracet 898 conforms compositionally with FDA Regulation 175.105.
