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
Applications & Uses
- Applications
- Adhesive & Sealant Type
- Coating Type
- Use Level
- 0.3 - 0.6% (Synthetic resin plasters), 0.3 - 0.8% (Dispersion adhesives), 0.4 - 0.9% (Powder paints), 0.5 - 1.0% (Full-tone paints), 0.5 - 1.0% (Water-based paints for indoor and outdoor applications)
- Application Technique
- 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.
Properties
- Physical Form
- Typical Properties
- Solubility
- 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.
- Stability
- 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.
- Note
* 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.

Storage & Handling
- Shelf Life
- 6 months
- Storage Conditions
- 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.
