Product Intelligence
Nitofill Accelerator - Technical Details, Specifications, and Features
Overview
Nitofill Accelerator is an optional additive specifically designed to hasten reaction times in Nitofill polyurethane injection resins. It functions as a chemical accelerant that allows users to modify and control the reaction profile of Nitofill products based on specific job site conditions.
Primary Applications
Nitofill Accelerator is used to accelerate reaction times in the following Nitofill products:
- Nitofill PU130 - Hydrophobic polyurethane injection resin
- Nitofill PU150 - Hydrophilic polyurethane injection resin
Typical applications include:
- Sealing against leaking cracks and joints in concrete and masonry structures
- Sealing against water infiltration in masonry and brickwork
- Void filling and back grouting in concrete structures
- Sealing fractures and failed joints in concrete
Key Advantages
- Variable reaction times - Allows customization of reaction profiles to suit job-specific conditions
- Optional use - Not mandatory; can be added only when accelerated curing is required
- Flexible dosing - Concentration can be adjusted based on environmental conditions and project requirements
Design Criteria and Dosage
Nitofill Accelerator is mixed with Nitofill PU130 or Nitofill PU150 at the following rates:
- Dosage range: Between 2% and 5% by weight per 20kg drum
- Maximum concentration: Up to 5% per 20kg drum, depending on required reaction time
- Application note: Each job will have varying conditions, so customers should perform their own trials to determine the optimum amount of accelerator for each specific application
Reaction Data - Nitofill PU130
The following reaction data is based on laboratory testing with 2.5% water addition at various temperatures and accelerator concentrations:
Temperature Performance (2.5% Accelerator)
| Temperature (°C) | Initiation Time (seconds) | Expansion Time (min:sec) | Foaming Ratio |
|---|---|---|---|
| 10 | 50 | 3:15 | >20x |
| 20 | 19 | 2:10 | >25x |
| 25 | 15 | 1:15 | >28x |
| 30 | 11 | 0:55 | >31x |
Variable Accelerator Concentrations (at 25°C)
| % Accelerator | Initiation Time (seconds) | Expansion Time (min:sec) | Foaming Ratio |
|---|---|---|---|
| 0.00 | 43 | 5:20 | >18x |
| 1.25 | 23 | 2:50 | >21x |
| 2.50 | 15 | 1:15 | >28x |
| 5.00 | 12 | 0:55 | >29x |
Product Supply and Packaging
Nitofill Accelerator 1kg: FC300901-1KG
The product is supplied in 1 kilogram containers, facilitating precise measurement and controlled addition to the polyurethane base product.
Storage Requirements
- Storage location: Keep in a dry store in original, unopened packs
- Conditions: Maintain dry storage conditions to preserve chemical properties
- Container integrity: Store only in original, unopened packaging
Application Instructions
Procedure:
- Nitofill PU130 or PU150 reacts with water to form polyurethane foam
- Add the accelerator to Nitofill PU130/PU150 before injection
- Maximum dosage: Up to 5% per 20kg drum, depending on required reaction time
- Mix thoroughly to ensure homogeneous distribution
Important consideration: As each job presents varying site conditions (temperature, humidity, concrete moisture content), customers must perform preliminary trials to identify the optimum accelerator concentration for their specific application.
Safety and Documentation
- Safety Data Sheet (SDS) is available from the Fosroc website
- Technical Data Sheet (TDS) must be read carefully prior to use
- Emergency contact: In emergencies, contact any Poisons Information Centre (phone 13 11 26 within Australia) or a doctor for advice
- Application or performance data may change from time to time
Product Disclaimer
The Technical Data Sheet summarizes the best knowledge of the product, including usage and application instructions based on available information at the time of publication. Users should read the TDS carefully and consider the information in the context of their specific application, including in conjunction with any other products and the type of surfaces to which the product will be applied.
