Visco Elastic Coating


A unique viscous elastic technology

VISCOTAQ® is a worldwide patented viscous elastic pipeline technology coating that is used for corrosion prevention of pipelines, storage tanks, soil to air transitions, above ground fl anges, pipe crossings and in the ditch applications. VISCOTAQ® also offers a unique waterproofi ng line of products to stop water infi ltration at pipe casings, buildings, vaults, storm drains, sewer lines and more. VISCOTAQ® products have been tested extensively by external laboratories, international oil and gas companies as well as in fi eld trials. The VISCOTAQ® products differentiate from any other product by being a synthetic viscous elastic solid, combining excellent adhesion based upon the Van Der Waals bonding principle, while being a solid with no dripping behavior.

Serving the Industry

VISCOTAQ® is a unique viscous-elastic amorphous a-polar poly-olefi n for the protection against corrosion of underground and above ground substrates in the pipeline industry, petrochemical industry, utility and water industry. VISCOTAQ® has been devel-oped in cooperation with leading companies in the oil and gas industry and polymer engineering companies to meet the demand for new viscous elastic coating products with unique and better properties for the protection of shaped and non shaped substrates. The result is a product that offers the pipeline industry an unrivaled technology when it comes to corrosion prevention.

The philosophy behind VISCOTAQ®

The philosophy behind the development of VISCOTAQ® is that, unlike other coatings, VISCOTAQ® always has a permanent and intimate contact with the surface of the substrate. The viscous mod-ulus and the elasticity modulus of the material are designed in such a way that the viscosity modulus gives permanent wetting charac-teristics, forcing the material to fl ow into the pores and anomalies of the substrates, whereas the elasticity modulus gives the strength and elasticity of a solid. Moreover, VISCOTAQ® eliminates typical problems that occur during pipeline rehabilitation in the fi eld and the problems of different phenomena that occur in practice.

How VISCOTAQ® solves typical pipeline corrosion problems

Elimination of salt and osmosis problems

Due to the very low permeability of water, its a-polar behavior and extremely good adhesion on a molecular level, VISCOTAQ® inhibits water molecules from traveling to the surface of the substrate. In conjunction with its low viscous characteristics, no pressure can build behind the coating that could cause blisters and de-lamination.

Elimination of adhesion problems and surface preparation problems

VISCOTAQ® bonds on the principle of Van Der Waals bonding, creating an intimate contact with the substrate. VISCOTAQ® has a low surface tension and keeps “wetting” the surface. Due to the viscous-elastic state and its formulation, VISCOTAQ® will keep this bond permanently for decades to come. VISCOTAQ® bonds aggressively to almost any surface and is forgiving when it comes to surface preparation. The minimum surface preparation for use is ST-2 / SSPC3, although a blasted surface SA21/2/SSPC10 is strongly recommended.

Elimination of problems with aggressive soils, MIC and degradation

VISCOTAQ® is based upon low molecular weight amorphous o polar polyolefins with no reactive groups, free radicals or solvents. Therefore, the material is 100% inert and stable, safe and non-hazardous. With the elimination of water and no sulfide or nitrogen available in the polymer chains, all essential and necessary components for MIC are eliminated, Due to its inor characteristics and permeability for water, VISCOTAQ exhibits outstanding performance in oreos with aggressive soils, high and low pH and high sulfur and chloride contents.

Elimination of shear stress problems, sliding

To guarantee ultimate corrosion prevention, VISCOTAQ® remains in a pliable state during its lifetime. Therefore VISCOTAQ® has been extensively tested in conjunction with different protective outer layers to simulate shear stress. Unlike other products, VISCOTAQ® has shown excellent resilience against shear stress due to the combination of the appropriate outer layer os well as the viscous-elastic solid state of the material.

Manufactured under ISO 9001 and and stringent quality controls

VISCOTAQ® is manufactured under ISO 9001 standards from raw materials to end product During this process, many quality control checks are in place to guarantee the highest quality. In addition to in-house quality control, VISCOTAQ® has been tested thoroughly by independent accredited laboratories

VISCOWRAP-ST

VISCOWRAP-ST is a viscous-elastic self healing wrap coating for the protection of under- and aboveground substrates against corrosion. VISCOWRAP-ST can be used in environments or on substrates with an ambient or surface temperature up to + 71° C / + 160° F.

VISCOWRAP-HT

HTVISCOWRAP-HT is a viscous-elastic self healing wrap coating for the protection of under - and aboveground substrates against corrosion. The material can be used in environments or on substrates with an ambient or surface temperature up to + 100° C / + 212° F.

VISCOPASTE

VISCOPASTE is viscous-elastic self healing paste for the protection of under - and aboveground substrates against corrosion. The material can be used in environments or on substrates with an ambient or surface temperature up to + 71° C / + 160° F.

EZ-WRAP

EZ WRAP is viscous-elastic self healing wrap coating for the protection of under- and aboveground substrates against corrosion and water fi ltration. EZ-WRAP has a polyester top coating that can be painted. The material can be used in environments or on substrates with an ambient or surface temperature up to +65° C/+149° F. EZ-Wrap has been originally developed for the protection of tank chimes where it is combined with VISCOSEALANT.

PVC OUTER WRAP

VISCOTAQ PVC Outer Wrap is a Heavy Duty PVC in the form of a roll. The tape is used as an Outer Wrap for the mechanical protection of VISCOTAQ products against soil stress, back fill procedures and other forms of mechanical impact. Furthermore, it provides a continuous external pressure to the VISCOTAQ corrosion prevention inner material and accelerates the process of the formation of a homologue continuous inner coating. VISCOTAQ PVC Outer Wrap is produced from a High Quality PVC with an excellent resistance to hemicals and is wrapped with a 50% overlap onto the VISCOTAQ corrosion prevention coating. The material is applied onto the substrate by hand or by means of a tape wrap machine
