Alcogum SL-78 Acrylic National Starch and Chemical-Alco Chemical Rheology Modifiers / Thickeners >> Alkali-Swellable Acrylic polymers (ASE/ HASE) Acrylics/ Acrylates Rubber - Elastomer (Chloroprene, Butyl …) PU - Prepolymers ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Water-based ALCOGUM™ polymers are pre-activated high molecular weight rheology modifiers used to viscosify a wide range of adhesive compounds. ALCOGUM thickeners provide stable viscosity over a broad pH range and are resistant to biological degradation. ALCOGUM SL-78 is an alkali activated rheology modifier. ALCOGUM SL-78 is a member of the ALCOGUM SL-SERIES line of rheology modifiers covered by U.S. Patents. This polymer is an acrylic associative emulsion polymer formulated to give structure to filled compounds for use in a wide range of applications. For neutralization purposes, ALCOGUM SL-78 has an equivalent weight of 20.6(a). ALCOGUM SL-78 can be used to viscosify water-based compounds. Optimum performance is achieved between pH 8 and 10. When added to alkaline pH systems, pre-dilution may allow better mixing. The water solutions of associative acrylic polymers have been shown to undergo an increase in viscosity when used in conjunction with nonionic surfactants. Alkali activated rheology modifier. Acrylic associative emulsion polymer formulated to give structure to filled compounds for use in a wide range of applications. Can be used to viscosify water-based compounds. Provides stable viscosity over a broad pH range. Offers resistance to biological degradation.
