Sika® Stabilizer-4 R IN
Biopolymer viscosity-modifying admixture (VMA) for stable concrete
Product Overview
Sika® Stabilizer-4 R IN is a biopolymer-based viscosity-modifying admixture (VMA) that increases the stability and cohesiveness of concrete and mortar. By thickening the mix and binding the paste, it controls bleeding and resists segregation even where water content runs high or the fines content is low, while improving pumpability and producing a homogeneous, robust mix that is far less sensitive to small batching variations. It is typically combined with a superplasticiser such as SikaPlast® or Sika® ViscoCrete® to deliver flowable yet stable self-compacting concrete. Ready-mix producers, pumping contractors and shotcrete teams rely on it to keep mixes uniform from batch to batch. Space Arc Engineering, an Authorized Project Distributor for Sika in India, supplies Stabilizer-4 R IN with mix-design guidance for SCC and pumped-concrete projects.
Features & Benefits
- Increases internal cohesion for a stable, robust concrete or mortar
- Controls bleeding and resists segregation, even at higher water content
- Makes the mix less sensitive to minor batching and material variations
- Improves pumpability for easier placement over distance and height
- Delivers a homogeneous mix that stays consistent batch to batch
- Compatible with all cement types and Sika superplasticisers for SCC
Technical Highlights
| Coverage | Dosed at 0.2% to 1.0% by weight of cement or binder; confirm via project trials. |
| Strength | Functions as a stabiliser rather than a strength enhancer; mechanical data — refer to TDS. |
| Performance | Raises cohesion, suppresses bleeding and segregation, and improves pumpability of the mix. |
| Application Conditions | Store dry between +10°C and +40°C, protected from sunlight and frost; stir well before use. |
| Packaging | Supplied in 50 kg or 230 kg containers; hazy viscous liquid, approx. 1.00 kg/l at 25°C, pH ≥ 6. |
Applications
- Self-compacting concrete (SCC) for congested or architectural elements
- Pumped concrete placed over long distances or heights
- Shotcrete and sprayed-concrete mixes requiring cohesion
- Site-batched concrete with variable aggregate quality
- Low-fines-content mixes prone to bleeding and segregation

Frequently Asked Questions
What does Sika Stabilizer-4 R IN do?
It is a viscosity-modifying admixture (VMA) that increases the cohesion and stability of concrete and mortar. It controls bleeding and segregation and improves pumpability, which is especially useful in self-compacting and pumped concrete.
Can Stabilizer-4 R IN be used with a superplasticiser?
Yes. It is designed to work alongside superplasticisers such as SikaPlast or Sika ViscoCrete, combining high flow from the superplasticiser with the stability and segregation control provided by the VMA.
What is the dosage of Sika Stabilizer-4 R IN?
The typical range is 0.2% to 1.0% by weight of cement or binder. The exact dosage should be finalised through trials, as it depends on the mix design, fines content and required stability.
Does Sika Stabilizer-4 R IN need to be stirred before use?
Yes. As a viscous biopolymer liquid, it should be stirred thoroughly before use and stored in dry conditions between +10°C and +40°C, protected from sunlight and frost. Shelf life is 6 months from production.
