Elastometric Polymer

Elastometric Polymer

General Description
Sigmacheme's ferro Prime is an elastomeric formulation specifically formulated for the protection of steel surfaces form corrosion. At the same time it provides excellent adhesion between old and new concrete as well as steel. As cement is brittle in nature and has poor tensile and flexural properties with the result it tends to come out form the steel surface on the slightest impact. Sigmacheme's ferro prime helps gaining the crucial bond between steel and cement and thus creates an alkaline medium around steel so as to prevent it from corrosion.

Advantages

• It is highly alkaline elastomeric polymer.
• It is mixed with cement forming a co matrix of cement and polymer. The high compression property and alkalinity of cementitious are tremendously increased by high alkalinity, high flexural strength and extra adhesion of polymer thus giving long term protection to steel against corrosion.
• The treatment can be provided at site which is particularly useful for repair jobs.
• It being cement coated, do not suffer any bond loss, when embedded in concrete where as epoxy coated bars are known to suffer substantial bond loss with concrete.

Use

• Protection to M.S. structures in exposed as well as marine environment.
• Rebars in new R.C.C. structures.
• H.T. wire in pre stressed concrete pipes.
• Pre stressed cables / strands. etc.
• Bonding coat between old and new concrete.

Application Guidelines

• Clean the steel surface. Make it free from any loose dust, rust scale etc. using wire brush, steel wool, etc.
• Apply sigmacheme,s rust ceaser by following the procedure given in its literature.
• Prepare a homogeneous mix of Ferro prime and fresh cement in a ratio 1:1 by weight. Apply another coat in full surface of the steel by brush.
• After the first coat is set, apply another coat in the some way.

Coverage
Approximately 90 sqft. -110 sqft., per kg. of ferro Prime per coat depending upon steel surface.

Shelf Life
Upto 6 months when kept in cool, dry place in tightly sealed containers.

Packing
Available in 1 kgs., 5 kgs. and 20 kgs. Packing.
