PRODUCT DATA SHEET Sika® ViscoCrete® G-2 High-Performance Superplasticizer/ HRWR DESCRIPTION CHARACTERISTICS / ADVANTAGES Sika® ViscoCrete® G-2 is a high-performance superplasticizer and water reducer based on Sika® ViscoCrete® polycarboxylate polymer technology. Sika® ViscoCrete® works based on a combination of electrostatic forces and steric repulsion effects. Thus, solid particles can be effectively dispersed. The benefits of Sika® ViscoCrete® G-2 include, but are not limited to the following: ▪ High water reduction ▪ Excellent flowability ▪ Rapid adsorption ▪ Very low retardation ▪ Compatible with other additives ▪ Free of formaldehyde and ammonia USES Sika® ViscoCrete® G-2 is formulated for applications in systems with high calcium sulfate content or pure gypsum binders. The product is especially suitable for the manufacture of gypsum products like: ▪ Gypsum boards (also: plasterboards, wallboards), partition panels, ceiling tiles ▪ Gypsum fiberboards, building elements, blocks ▪ Building plaster, render, stucco, bonding/filling compound, molding plaster, dental and medical plaster Especially when utilized for gypsum board production the use of Sika® ViscoCrete® G-2 may result in: ▪ Short mixing time ▪ Reduced placing- and compacting efforts ▪ Shorter drying time ▪ Improved shrinkage and creep behavior ▪ Higher strength adjustable ▪ Reduced water consumption and less waste water ▪ Reduced energy consumption and CO2-emission ▪ Increased production rate and thus enlarged capacity PRODUCT INFORMATION Composition Aqueous solution of modified polycarboxylates IBC of 1000 kg net Bulk supply on demand Appearance / Colour Light yellowish liquid Shelf life 12 months shelf life from date of production if stored properly in undamaged, unopened, original sealed packaging. Storage conditions Storage at temperatures between 5 °C and 30 °C. Protect from direct sunlight, frost and contamination. PRODUCT DATA SHEET Sika® ViscoCrete® G-2

Conventional Dry Material Content Total Chloride Ion Content Equivalent Sodium Oxide TECHNICAL INFORMATION Specific Advice Differences in calcium sulfate binder type, raw material sources, calcining methods, age and storage conditions of the binder and other individual parameters at the plant and/or job site can influence the superplasticizer consumption of gypsum binders. At high dosage bleeding and/or segregation may occur as well as retardation of setting. Note: ▪ Preliminary testing is required to determine the exact dosage for your specific conditions.
