PERAMIN SRA
Antishrinkage additive
DESCRIPTION OF PRODUCT
Peramin SRA – antishrinkage additive for cement, dry building systems and liquid solutions. Peramin SRA reduces the shrinkage of the material as plastic stage and at the stage of solidification. In the hardening process, the product expands and reacts on a chemical level, changing the mechanisms of shrinkage reaction. Through the use of Peramin SRA можно to reduce shrinkage up to 50% in the initial stage and after 28 days. The probability of cracking of the material, respectively, is significantly reduced.
ADVANTAGES
The reduction of shrinkage in the plastic stage up to 50%
- reduction of shrinkage at the stage of drying up to 50%
- reducing the alkali content of up to 30%
- uniform quality of the product
Application
Peramin SRA suitable for dry mortars, liquid mortars and dry construction mixtures, especially based on Portland cement and cement systems with a high content of alumina. Where required, extended working condition of the mixture, Peramin SRA reduces the critical plastic shrinkage.
Peramin SRA can also be used for self-leveling compounds, dry mortars and dimensionally stable liquid solutions. These properties are described in detail in the Instructions for use Paramin. Peramin SRA is compatible with almost all existing redispersible powder systems, accelerators, retarders, and superplasticizers powder Peramin series. However, we recommend testing the product for best use.

DOSAGE
Depending on the scope of dose Peramin SRA may vary within a range of
Of 0.3-0.5% relative to weight of dry components. Peramin SRA low temperature or a small overdose can cause a mild effect of slowing down the process.
Excess dosage will lead to a slower setting.
METHODS OF CLEANING
A small amount Peramin SRA may be removed with a brush.
S. H. E. (Safety, health, environment)
Perstorp industrial group is currently working on the application of systems for Safety, Health and environment based on ISO 14001 and EMAS (Scheme of environmental management and audit). Several companies within the group were ISO 14001 certified and registered in EMAS. Annually environmental report group.
Additional information on the Safety, Health and environment is located in a separate Specification on Safety.
PACKAGING AND STORAGE
Peramin SRA is supplied in bags weighing 500 kg in waterproof paper bags with plastic coating inside. The net weight is 20 kg/bag. We can provide other packing upon reservation.
Peramin SRA should be stored in a dry place as it absorbs moisture. In closed bags industrial packaging can be stored year. Opened bags should be tightly repackaged and used in a short time.
