AGOCEL® AC 1115

AGOCEL® AC 1115 optimizes important criteria in water-based paints and synthetic resin plasters such as storability, processing, yield and adhesion on critical substrates.

Within the total activity spectrum of AGOCEL® AC 1115, the following properties stand especially out:

• Easy incorporation into aqueous systems due to controllable hydration
• Very distinct water retention capacity
• Very good suspending power and protective colloid effect
• Excellent cost effectiveness

• The development of new paints and plasters facilitating an easy processing, high productivity and yield requires the use of very suitable hydrocolloids.
• AGOCEL® AC 1115 is largely applied for controlling the viscosity, rheology and water retention when producing:
  • Indoor paints
  • Outdoor paints
  • Full-tone paints
  • Powder paints
  • Synthetic resin plasters
  • Dispersion adhesives for tiles
• A special surface treatment of AGOCEL® AC 1115 facilitates an easy, homogeneous introduction of the powder into prepared, neutral or acid reacting aqueous phases when producing paints and plasters. The moment of hydration and as a consequence the beginning of the viscosity development can be controlled, if necessary, through a change in the pH value.
• Should the swelling be retarded over a longer period of time due to the selected production technology, we recommend adjusting a slightly acid pH range (pH 4.0 – 5.0). Furthermore, we recommend regulating the pH value at about 9.0 in case a quick swelling is required after the powdery components have been dispersed. A further change in the pH value in a wide range after swelling has no further influence on the hydration properties.
• If AGOCEL® AC 1115 is added to aqueous phases with an alkaline reaction, an immediate swelling starts together with the risk of a lump formation and a more complicated homogenization. Therefore we recommend using powerful stirrers at high speed or a preblend with powdery pigments or fillers in case the working method cannot be changed.
• The multifunctional properties of AGOCEL® AC 1115 facilitate the reduction of recipe components and cost in many cases.
• The optimal application concentration of AGOCEL® AC 1115 varies depending on the application field and the selected product recipe.
• AGOCEL® AC 1115 does not contain any preservatives.
• We highly recommend adding sufficient amounts of preservatives to aqueous ready to use products.

• Colloidally soluble in cold or warm water with retardant swelling.
• Changes in the pH value influence the swelling speed; pH values < 7.0 retard the hydration, pH values > 7.0 accelerate it.

• After hydration AGOCEL® AC 1115 is stable within a wide pH range and has a stable viscosity.
• Boron ions lead to a reversible gel formation at pH values > 7.0.

* Measured in a 2% aqueous solution at a pH value of 8.5, 20°C and 2 hours hydration time with Brookfield RVT, 20 rpm.

• Store in cool and dry conditions in closed original containers.
• We recommend not exceeding a storage time of six months.
• Higher storage temperatures lead to an irreversible drop in viscosity.
