MasterGlenium® SKY 8587 
High-performance super plasticiser based on PCE (polycarboxylic ether) for concrete.

DESCRIPTION: MasterGlenium SKY 8587 is an admixture of a new generation based on modified polycarboxylic ether. The product has been primarily developed for applications in high performance concrete where the highest durability and performance is required. MasterGlenium SKY 8587 is free of chloride & low alkali. It is compatible with all types of cements. 

RECOMMENDED USES: • Production of Rheodynamic concrete  • High performance concrete for durability • High early and ultimate strength concrete • High workability without segregation or bleeding • Precast & Pre-stressed concrete • Concrete containing pozzolans such as microsilica, GGBFS, PFA including high volume fly ash concrete.

FEATURES AND BENEFITS: • Elimination of vibration and reduced labour cost in placing • Marked increase in early & ultimate strengths  • Higher E modulus • Improved adhesion to reinforcing and stressing steel • Better resistance to carbonation and other aggressive atmospheric conditions • Lower permeability - increased durability • Reduced shrinkage and creep.

TEST CERTIFICATION/APPROVALS :• ASTM C494 Type F &G • EN 934-2 T3.1/3.2 • IS 9103: 1999 

STORAGE /SHELF LIFE: MasterGlenium SKY 8587 must be stored where temperatures do not drop below +5°C. If product has frozen, thaw at +5°C or above and completely reconstitute using mild mechanical agitation. Do not use pressurized air for agitation. Store under cover, out of direct sunlight and protect from extremes of temperature. Shelf life is 12 months when stored as above. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging.  For specific storage advice consult your local BASF representative. 

PRECAUTIONS: As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until product fully cured or dried).  Treat splashes to eyes and skin immediately. If accidentally ingested, seek immediate medical attention. Keep away from children and animals. Reseal containers after use.

DESCRIPTION: MasterPolyheed 8632 is an economical admixture based on modified polycarboxylic ether. The product has been primarily developed for applications in ready mix and site-batched concrete. MasterPolyheed 8632 is specially designed to allow considerable reduction of mixing water while maintaining control on extend of set retardation.  MasterPolyheed 8632 is free of chloride & low alkali. It is compatible with all types of cements.

RECOMMENDED USES: ??? Ready mixed concrete ??? Long-distance transporting ??? Pumped concrete ??? High workability without segregation or bleeding ??? High performance concrete for durability ??? Congested/complex reinforced sections ??? Mixes requiring >20% water reductions.

FEATURES AND BENEFIT: ??? Good dispersion even in mixes with high fines ??? High workability for longer periods ??? Lower pumping pressure ??? Resistance to segregation even at high workability ??? Extended setting with longer workability ??? Reduced water content for a given workability ??? Higher ultimate strengths ??? Increased ease in finishing concrete.

STORAGE /SHELF LIFE: MasterPolyheed 8632 must be stored where temperatures do not drop below +5°C. If product has frozen, thaw at +5°C or above and completely reconstitute using mild mechanical agitation. Do not use pressurized air for agitation. Store under cover, out of direct sunlight and protect from extremes of temperature. 

 PRECAUTIONS: As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapor until product fully cured or dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek immediate medical attention. Keep away from children and animals. Reseal containers after use. Do not reuse containers for storage of consumable item. 

DOSAGE: Optimum dosage of MasterPolyheed 8632 should be determined with trial mixes. As a guide, a dosage range of 400 ml to 1200ml per 100kg of cementitious material is normally recommended. Because of variations in concrete materials, job ite conditions, and/or applications, dosages outside of the recommended range may be required. In such cases, contact your local BASF representative

Effects of over dosage: A severe over-dosage of MasterPolyheed 8632 can result in the following: ??? Reduced permeability ??? Long extension of initial and final set ??? Increase in air entrainment ??? Bleed/segregation of mix, quick loss of workability ??? Increased plastic shrinkage.
A slight overdosing may not adversely affect the ultimate strength of the concrete and can achieve higher strengths than normal concrete, provided it is properly compacted and cured. Due allowance should be made for the effect of fluid concrete pressure on form work, and stripping times should be monitored.
