rheology

Rheology modifier for mortar, gypsum-plaster and concrete, improving their properties in both the fresh and hardened state. Properties CIMSIL A55 is a chloride-free thixotropic additive specifi cally developed to act as an anti-sagging/anti-slipping agent, CIMSIL A55 fully develops its rheological properties by activation in the presence of cement or gypsum. It improves workability and visual fi nish in the systems to which it is incorporated. CIMSIL A55 gives mortar, plaster and concrete the following properties: • Thixotropy • Workability • Improves adherence to the substrate • Improves pumpability • A voids both tile slipping and mortar sagging • Decreases bleed and segregation • Gives homogeneity and cohesiveness to the finish product • Improves the surface finish Fields of applications • Pumpable concrete • Decorative concrete • Precasted concrete • Rendering mortar • Tile adhesive mortar • Waterproof mortar • Fill-in mortar • Self-levelling mortar • Repair mortar • Gypsum-based spray plaster • Gypsum-based thin layer plaster • Gypsum-based adhesive plaster Dosage Dosage of CIMSIL A55 varies according to the type of application. However, dosages between 0.25 and 1%, referred to the weight of the cement are recommended.

A readily biodegradable modified amine oxide used to produce clear, stable, colorless sodium hypochlorite or hydrogen peroxide gels. Soluble in water, alcohol and glycols. Insoluble in most solvents and oils.

Rheological additive for intermediate polarity systems. PANGEL B20 is a powdered additive with a high thickening and anti-settling capacity for intermediate polarity systems, particularly recommended for systems based on aromatic and unsaturated polyester type solvents. Properties PANGEL B20 is particularly recommended to provide thixotropic, suspension and sagging-resistance properties to systems based on aromatic and unsaturated polyester type solvents, PANGEL B20 does not require the use of a polar activator for its dispersion. PANGEL B20 provides a strongly pseudoplastic character, producing high consistency levels without affecting viscosity during application. It exhibits its high effectiveness as anti-settling additive in formulations with high solid contents. Use of PANGEL B20 has the following advantages against other conventional additives: •Coatings and paints: Prevents settling of pigments and fillers; controls sagging without aggravating leveling; high stability during transportation and storage. •Printing inks: Improves consistency and prevents settling of pigments. •Unsaturated polyester putties: Improves consistency and workability. •Paint strippers: Improves stability and facilitates stripping action.•Greases based on vegetal oil: High thickening capacity; good stability at high temperature. •Asphalt coatings: High thickening capacity; application in thicker layers; sagging control. • Sealants and joints: Improves wetting and suspension properties; controls sliding. •Others: Control of sagging and dripping; improves stability
