Anuchlor CZP 500 : High Build Chlorinated Rubber Primer  


Product Description :


Anuchlor CZP 500 is a high performance high build primer for structural steel surfaces based on plasticised chlorinated rubber and pigmented with zinc phosphate rust inhibiting pigment. It can be applied on manually cleaned steel surfaces where blast cleaning is either impractical or cost-restrictive. It can be overcoated with conventional and chlorinated rubber topcoats.

Features and Benefits :

Easy to apply and can be applied via airless spray, conventional spray and brush.

While inferior surface preparation can never be recommended, Anuchlor CZP 500 has shown to tolerate though with shorter life, power-tool and hand-cleaned steel.

Renders hard, inert film showing excellent resistance towards dilute acids, alkalis, certain salts, oxidizing agents, aliphatic hydrocarbons, alcohols, mineral oils, greases etc.

Extremely durable and weather resistant.

Non-toxic and cost-effective.

Has very low water and water vapour permeability.

Suitable for varied end applications i.e. ideal for high humidity, moisture, marine atmospheres, heavy rains, high temperatures, damp conditions, very dusty and fungus prone conditions.

Impart excellent inter-coat adhesion properties.


Recommended uses :


Fertilizer plants

Sewage farms

Concrete Storage Tanks

Water Treatment Plants

Structural Steel

Galvanized Iron

Bleacheries and laundries


Pulp and Paper Mills

Chemical Plants

Marine and shore installations

Swimming Pools

Food Processing Plants

Areas of excessive moisture

Petro-chemical Plants


  Surface Preparation :  

Steel - The surface should be blast cleaned to SSPC-SP 10-63T or NACE No. 2 i.e. loose rust and scales, dirt, grease, oil, paint, wax, weak oxide films and other contaminants should be removed. It means that at least 95% of any given square inch has the appearance of white metal and the remainder is limited to slight discolourations. Blast cleaning to SSPC-SP 5-63 or NACE No. 1 is recommended where heavy corrosive conditions exist. That means a surface with a grey metallic colour, slightly roughened to form a suitable anchor pattern for coatings. This surface is free of all oil, grease, dirt, mill scale, rust, corrosion products, oxides, paint and other foreign matter. In absence of blast cleaning, prepare the metal surface by wire brushing, sanding, grinding, scrapping or chipping with hand or power tools. Remove all the contaminants. Apply a coat of Anuchlor CZP 500 followed by 2-3 coats of Anuchlor 555 LB Chlorinated Rubber Enamel. Anuchlor - MIO can be used as intermediate coat depending on service requirements.

Galvanized Iron - Remove dirt, dust, oil, old paint etc. Degrease the surface with degreasing solvents like xylene or tri-chloroethylene. Apply one coat of Anuprime - 291 Wash Primer for obtaining maximum adhesion. Apply one coat of Anuchlor CZP 500 followed by 2-3 coats of Anuchlor 555 LB. Anuchlor - MIO can be used as an intermediate coat depending on service requirements

Product Limitation :

Anuchlor CZP 500 is not resistant to most solvents, animal and vegetable oils and fats common in dairies, packinghouses and sewage treatment facilities.
Do not use on floors.
Epoxy and polyurethane topcoats are not suitable.
Notes :-  
Brushes and spray equipments should be cleaned with Anusol - CRT Thinner.
The contents should be stirred thoroughly prior to use.

When overcoating the weathered or aged Anuchlor CZP 500, ensure that the coating is fully free from all contamination such as oil, dust, grease, stains etc.

This coating should always be thinned with Anusol - CRT Thinner. The use of alternative thinners can severely inhibit the curing mechanism of the coating.
