ESTER VE

Anti acid- flexible coating

Description

ESTER VE is a two component product consisting of:

  •  component A: mixture of polyfunctional prepolymers and liquid additives.
  •  component B: polymerization catalyst.

 

Once fully cured, the material exhibits excellent chemical resistance and corrosion resistance, while maintaining an exceptional combination of temperature resistance and flexibility.

Also available:

  • ESTER PE/VE component C to accelerate the product when room temperature is below +15°C;
  • ESTER PE/VE component D as the necessary additive for the finishing layer realization.
  • ESTER VE is available in its transparent or coloured versions.

 

Usage field

ESTER VE is used in the production of acid-resistant floors and finish coatings for different types of building surfaces and equipment such as storage tanks, process vessels, pipes, conduits, etc.

Chemical Resistance:

  •  in contact with liquids up to a maximum working temperature of +105°C;
  •  in contact with gases up to +180°C.

 

These conditions may vary depending on the chemical nature of the liquid in contact. Please contact NORD RESINE technical department for further specification.

 

Packaging

ESTER VE is available in packs of 1, 5 and 20 kg.

Application

Substrate Preparation:

carefully check the substrate to make sure it is a suitable and structurally sound base;

the kind of treatment to be performed shall be chosen, depending on the actual state of the area, between the following:

  • hot water pressure washing;
  • washing by means of acids;
  • sanding;
  • diamond grinding;
  • blasting or scarification (only in case of floors).

In this way dust, dirt, grease, oil, old adhesive or paint, laitance, rust, mildew and other extraneous materials will be removed.

The depressions and inconsistencies of the surface must be evened out with GROVE RIPRISTINO or RASANTE 2000 2K.

Average Consumption
  • ESTER VE (A+B): variable depending on reinforcement type.
  • ESTER PE/VE component C: from 0.1 to 0.3% depending on working room temperature.
  • ESTER PE/VE component D: 4% by weight or volume only on the last final coat.

 

 

 

To achieve a coating with a thickness of approx. 1 mm it is necessary to apply 1.10 kg/m2 of product (A+B).

Warning and informations

Before applying the finishing layer for any kind of working method always add ESTER PE/VE component D to the product.

  • The product can be brought into contact with water starting from the day after application.
  • When used for liquid foodstuff containment tanks, ESTER VE shall be used only after is fully cured (after the transfer of styrene traces is completed).
  • To reach full cure in a short time, few days at +30°C or 24 hours at 60°C are needed. Vapour is the best curing method.
  • Use acetone to clean tools.
  • It is a flammable product. Protect respiratory tract with a mask for organic compounds.
  • Read the Material Safety Data Sheet (MSDS).

 

Preservation

Store in a covered place, at room temperature between +10 and +30°C
