ANTI CORROSION COATING SYSTEM

  

 

Rounded Rectangle: Information on coverage, costs available upon request.

 

DESCRIPTION:

 

Protecto-Corogard is a two component Polyurethane based protective coating system with a unique organo-metallic ingredient. It is specially designed to protect a wide range of substrates from grease, acids, alkalis, coolants and other chemicals.

  

Protecto-Corogard's excellent adhesion and unmatched scratch and corrosion resistance makes it ideally suited for protecting machinery and equipment in chemical, plastic, textile, cement and marine industries. It also protects steel reinforcement rods, metal pipes and tubes and aluminium extrusions.

   

Environmental pollution due to nitrates and sulphates from vehicular emission has a highly corrosive effect on steel and concrete structures. This is further compounded by sodium chloride in the air especially in coastal regions. Protecto-Corogard can effectively guard against such factors and prevent premature collapse of RCC structures such as buildings, flyovers, bridges, water tanks, etc.

COATING SYSTEM

 

 

  

SALIENT FEATURES:

  

Outstanding Corrosion Resistance

It is resistant to various substances as illustrated in Table 1.

Excellent Adhesion

Protecto-Corogard strongly bonds to steel, aluminium, copper, brass, concrete, FRP and wood and will not peel off from the substrate even in severe environment.

Excellent Scratch and Abrasion Resistance

It withstands a high level of physical wear and tear as shown in Table 2.

Good Elasticity

Protecto-Corogard is very elastic and withstands expansion and contraction of the substrate without cracking.

Excellent Ultraviolet Resistance

Protecto-Corogard easily withstands ultraviolet rays when exposed to sunlight.

Excellent Antifungal Properties

Protecto-Corogard is highly resistant to fungal and microbial attack.

Good Temperature Resistance

Protecto-Corogard can withstand variations in temperature from - 25C to 130C.

Good Aesthetics

It comes in a wide range of colours and with a choice of glossy or matt finish. It can also be provided with an aluminized (silver) or Coal Tar (black) topcoat.

APPLICATIONS:

 

 

APPLICATION ON METALS

 

SURFACE PREPARATION: The surface is cleaned of oil, dirt and grease by means of solvents or emulsifiers. Rust and scales are removed by mechanical means like scrapping, wire brushing and rubbing with emery paper. Sand or grit blasting is used wherever possible to obtain a completely clean surface. Chemical methods using phosphating chemicals, rust convertors, etc. may also be used. Immediately after cleaning the surface a primer coat is applied.

 

PRIMER COAT: The primer coat which protects the substrate is available in a choice of anticorrosive pigments such as zinc phosphate, zinc chromate and red oxide. For highly corrosive environment a zinc rich primer is recommended. Protecto-Corogard 10 and Protecto-Corogard 40 are mixed thoroughly and applied evenly by brush or spray. Details of the primer coat are given in Table 3.

 

TOPCOAT: The primer coat is allowed to dry for 2-3 hours. Two topcoats are then applied over it keeping a gap of 2-3 hours between the coats. Details of the matt, glossy or coal tar modified (for underground structures) topcoat finishes are given in Table 3.

 

APPLICATION ON CONCRETE

 

Dirt and grease deposits are removed from the concrete surface by wire brushing and solvent/detergent cleaning. An acid wash using 5-10% hydrochloric acid is then given followed by thorough washing with large quantities of water. The surface is allowed to dry thoroughly. Small cracks and depressions in the concrete surface are filled up with a paste made by adding silica or talc to a mixture of Protecto-Corogard 10 and Protecto-Corogard 30. Three coats of Protecto-Corogard mixture (glossy or matt) are applied by brush or spray, keeping a gap of 2-3 hours in between coats. Details of these coats are given in Table 3.

 

APPLICATION ON F.R.P. AND WOOD

 

The surface is thoroughly cleaned and leveled with compatible leveling compound or with a putty made by adding silica or talc to a mixture of Protecto-Corogard 10 and Protecto-Corogard 30. Smoothen the surface with emery paper. Two or three coats of Protecto-Corogard mixture (glossy or matt) are applied by brush or spray keeping a gap of 2-3 hours in between coats. Details of these coats are given in Table 1.

Note: Use Protecto-Corogard 10G in place of Protecto-Corogard 10 for outdoor applications.
