Mycropast -AR 6557 Concrete Repair Agent

MYCROPAST -AR 6557 (Multipurpose) is a modified acrylic emulsion specially designed for use as a bonding aid and gauging liquid for cementitious systems. It is resistant to hydrolysis and can therefore be used for external applications. Mycropast AR 6557 is the recommended primer for the Mycro-primer cementitious repair system. It cures mortars using to prevent rapid drying out also Protect uncured mortar from frost and rain.

The incorporation of Mycropast AR 6557 in mortars and concretes improve the tensile strength, flexural strength, corrosion resistance and provides greater flexibility for crack bridging, better bonding, excellent water resistance, improved chemical resistance, and reduced shrinkage. The durability of Mycropast AR modified cement-based materials is higher due to the flexible butadiene chains. The improved workability induced in concrete by Mycropast AR is  associated with entrained air and scattering effect of surfactants used in polymer production. An increase in the flexural strength is associated with the presence of polymer membrane around and between cement particles and to the contribution of the intrinsic characteristic of rubber polymer.

Where to use:

➢ Toppings

➢ Repairs

➢ Levelling

➢ Under tiles waterproofing

➢ Repair of spelled concrete-floors, columns, beams, parapets, etc.

Features of Mycropast AR Compounds:

➢ Bonding agent: Mycropast AR is used as a bonding agent for cement mortar, concrete, and cement bond coats.

➢ Admixture: Mycropast AR is used as an admixture in cement slurry to improve its properties.

➢ Waterproofing: Mycropast AR is used in waterproofing preparatory works like bore- packing and V-groove packing.

➢ Cementitious pressure grouting: Mycropast AR is used in cementitious pressure grouting.

➢ Screeding works: Mycropast AR is used as a bonding agent for screeding works.

Advantages

➢ Prevents leakage & dampness

➢ It prevents cracking by improving flexural strength

➢ Reduces drying & aging shrinkage cracks

➢ Bonds strongly to concrete, masonry, stone work, plasters, steel, asphalt & most of the building materials

➢ Improvers erosion resistance & prevents corrosion

➢ Improves abrasion resistance of cement mix

➢ Enhances strength of a repair mortar & provides durability

Precautions & Limitations

➢ Do not add Mycropast AR directly to dry cement & aggregate mix.

➢ Maintain water-cement ratio as low as possible.

➢ Do not increase the dosage of Mycropast AR than the recommendation.
