Neoproof® PolyureaBrushable Technology vs. Spay-applied

Neoproof® Polyurea

1) Brushable – Easily Applied by roller

→ Economical Application!

- Also Sprayable!

Spray-Applied Polyurea

1) Only sprayable

Requires: a) heavy & extremely expensive equipment, b) personnel trained specifically to operate it

Neoproof® PolyureaBrushable Technology vs. Spay-applied

Neoproof® Polyurea

2) Aliphatic

→ Extreme resistance to UV

→ Ideal solution for exposed roofs

→No topcoat required

3) Excellent adhesion strength

Spray-Applied Polyurea

2) Both components aromatic

→ Very limited resistance to UV

→When exposed, UV triggers chaulking effect (polymer decomposing)

→ Requires aliphatic topcoat!

3) Instant drying

→ Does not penetrate to the substrate

Neoproof® Polyureavs. solvent-based PU-1K

Neoproof® PolyureaAliphatic amine + Aliphatic isocyanate → Polyurea

- Consistency in the film of the cured membrane, without bubbles on the surface or in the mass

- The mechanical properties in practice are the maximum

- The water absorption is zero

Solvent-based PU-1KPU-1K + Moisture → Polyurethane + CO2 (gas)

- Gas is produced from the reaction with moisture, which creates bubbles-blisteringthroughout the mass of the PU material

- In practice the mechanical properties are

worse

- The water absorption greater than

expected


The quality of the final finish of a waterproofing coating is directly related to its

• water absorption

• tear strength (or tensile strength)

• adhesion strength

Neoproof® Polyurea systems offer a uniform and continuous surface without bubbles and micro pores, which are a major problem in

the case of solvent-based

PU 1K coatings


Accelerated Weathering Test (QUV)

Executed with a specially designed device which operates continuously by repeating the following steps:

i. UVΒ radiation at 60OC

ii. Spraying with water

iii. Vapor condensation at 50OC

→ 2000 hours, 3000 hours, 4000 hours…..

Mechanical Properties

Neoproof® PolyureaEarly-rain Resistance

All Neoproof Polyurea versions exhibit excellent early-rain resistance:

• As soon as the solvent evaporates, all versions are rain resistant.

• Even before the solvents fully evaporate, Neoproof Polyurea versions will only exhibit a slight tackiness
