Alcogum SL 920

Highly efficient viscosity build.; Synergistic interaction with nonionic surfactants.; Liquid for ease of handling and metering.; Provides clear solutions and gels.

ALCOGUM SL 920 is listed on the TSCA confidential inventory. Contains no alkylphenol ethoxylate components.

ALCOGUM SL 920 is available in bulk, intermediate bulk and 55-gallon drums. Storage tanks should be plastic, fiberglass, or 316 stainless.; Pumps should be low-shear type, such as diaphragm or peristaltic type with all wetted parts and lines being stainless steel, plastic or Teflon . Mild steel, copper, brass and aluminum should not be used.; Filtering should be under low shear and volume flow conditions. Freezing should be avoided as it destabilizes the emulsion. The recommended storage temperature is 5-50°C (40-120°F). Dilution or pH adjustment of the product may require additional preservative to prevent biological growth.; Keep containers tightly sealed to the prevent emulsion from air drying and forming a film.

Add the emulsion slowly to the solution with good agitation, preferably as the last ingredient prior to neutralization. Dilution of the Alcogum® SL 920 with water can facilitate incorporation in viscous and/or alkaline formulations.. Optimum viscosity build occurs at or above pH 8. For consistent performance avoid partial neutralization and poor mixing. 0.219 parts Ammonium Hydroxide (28% ) to 1.0 part Alcogum® SL 920 (as received)0.130 parts Sodium Hydroxide (50%) to 1.0 part Alcogum® SL 920 (as received) High efficiency rheology modifier, surfactant synergy.
