Technical Information

DESCRIPTION

The Vortex Material comprises of a Plural Component, Polyurethane / Polyurea blended base, a low viscosity, non-temperature sensitive isocyanate catalyst formulation.

This unique and exclusive blend of materials results in an incredibly durable surface coating of extremely high impact resistance and durability, normally found in very expensive Polyurea blends normally 4 to 8 times the cost.

High chemical resistance, abrasion resistance and wear ability lend to a long lasting, industrial coating known as Vortex.

MECHANICAL BEHAVIOR

When investigating the property of a material with potential industrial application, it is normal to subject it to a number of standard and bespoke tests. In the case of Vortex, it was decided that the appropriate tests will have to include those which indicate its mechanical performance and its ability to resist water/moisture permeability.

TENSILE TESTS

These are in accordance to BS2561. Consisting of prepared narrow strips of material to be load-tested to failure while being pulled.

These tests are standard where both the pull action and elongation are 'normalised'. Force normalisation is by expressing the tensile action (or force in units of Newton) per unit area, i.e. square mille-metres (or mm2).

Hence there is normalised force in Newtons/mm2 = a (stress) and normalised deformation, namely stretch for unit length therefore stretch per unit length (in mm) is known as e (strain).

A third parameter is formed through dividing: This is known as Young's modulus of Elasticity E.

PERMEABILITY TESTS

This is the ability of Vortex to withstand water pressure from penetrating through it.

The study was intended to establish whether a specific thickness of Vortex, properly applied, could behave as a sheet of waterproof membrane, when sprayed on structural components, designed to perform under dry conditions.

ENVIRONMENTAL CHAMBER

This is a sophisticated piece of equipment which accelerates the peaks and troughs of temperature as judged to prevail within the British Isles.

A twenty year hot (+40 degree C) and cold (-10 degree C) cycle was simulated in order to investigate Vortex response under service extremes of temperature.

Test Outcomes Vortex successfully resisted high hydrostatic pressures equivalent to a water head of 46KN/m2 (approximately head of 45m of water) without any observed leaks through the material.

This included successful pressure resistance by 2-3mm thick spray which had even been subjected to temperature cycles in the Environmental Chamber.

Tensile testing showed results with consistency in mechanical behaviour.
The stresses under all conditions were not less than J=8.0 N/mm2. material distinctively reduced as exposure to environmental conditions increased. Nevertheless the ultimate strain... all=5.5% at the worst condition of freeze/thaw for 20yrs. Young's modules (material stiffness) increased progressively with prolonged exposure to environmental action.

The values progressed from E=265 N/mm2 (pristine material to E=331 N/mm2 at the end of 20yrs. simulated temperature extremes.
