100% SOLIDS
Purethane® coatings do not contain any solvents (zero VOC). They coat free of pinholes, holidays, blisters or craters and cure with no shrinkage.
HIGH CHEMICAL RESISTANCE
Purethane® is unaffected by nearly all acids and bases in dilute to medium concentrations. It is impervious to sea water, salt solutions, raw and oxygenated sewage, bleaches, petroleum, vegetable oils, salt solutions and many specialty chemicals. 
HIGHLY IMPERMEABLE
Purethane® is impermeable to most liquids and has very low water vapor transmission. Tests indicate that Purethane® completely prevents transmission of Oxygen at 1 Atm pressure. The highly impermeable nature of Purethane® coatings prevents corrosive gases or liquid from penetrating the coating and corroding metal surfaces or reinforcing bars in concrete.
ADHESION
Purethane® has excellent adhesion to steel. Concrete or wood substrates will break in tests with no effect on the Purethane® bond. High adhesion prevents mechanical damage and intrusion of corrosive liquids or gases under the coating.  
OUTSTANDING ABRASION RESISTANCE
Purethane® coatings have exceptional resistance to abrasion. Abrasive wear is 1/10th of mild steel. Purethane® is excellent for slurry lines, coal and aggregate chutes, in gas / liquid lines containing solid particulate, horizontal directional drilling and on hulls of icebreakers.
EXCEPTIONAL IMPACT RESISTANCE
Purethane® has unmatched impact resistance whether on steel or on soft substrates such as foam insulation. Purethane® coated pipelines can be buried with any backfill without causing any damage to the coating. The coating resists damage due to transport, handling and laying operations. Thus Cathodic protection currents are minimized leading to large savings in recurring costs.
CATHODIC PROTECTION
Cathodic protection voltages will not cause blisters or peeling of Purethane® coatings. Purethane® exceeds industry criteria for cathodic disbondment when tested according to ASTM G 8 / G-95 / DIN 30671.
 
 

ELONGATION AND FLEXIBILITY
Purethane® coatings are formulated to be sufficiently elastic while retaining high cross-linking and low permeability. Elasticity enables coatings to withstand thermal expansions and contractions of substrates. Tests show that Purethane® coatings will withstand cracks of up to 1.4 mm initiated in the concrete under the coating. A one-mm coating on a steel plate will bend over an 8mm mandrel without cracking.
EXCELLENT WEATHER RESISTANCE
Purethane® has excellent resistance to ultraviolet radiation as well as degradation by severe weather conditions. Accelerated weathering test for over 2,000 hours show no effect on the coating other than a change in color and slight surface chalking. The excellent weathering characteristics of Purethane® are confirmed by installations over 15 years old, practically unaffected by exposure.
UNLIMITED BUILD
Purethane® coatings can be applied from 0.5mm (20 mils) to 25mm ( 1000 mils ) thickness even on vertical surfaces in one application using multiple passes without sagging or distortion. Recommended thickness usually varies between 0.75mm ( 30 mils ) to 3.00mm (120 mils). 
RAPID APPLICATION AND CURE
Purethane® coatings are spray applied using plural component airless spray equipment offering high application rates. The applied coating cures rapidly and can be water immersed in 2 hours. Purethane® will cure at temperatures as low as (-) 40^oF/40^oC. Purethane® 385/9000 with a longer pot life is available for easy repair jobs by brush / squeegee and spray for self-leveling floors.
HYDROPHOBIC NATURE
Unlike most other 100% Solids Polyurethanes, Purethane® Coatings are hydrophobic in nature. Like Polyurea coatings, they are practically unaffected by damp environments during spray. They are much more applicator friendly and give fine finishes unlike the Polyurea coatings which are difficult to apply and have “orange peel” and flow / wetting problems. Adhesion to damp substrates (like Polyureas) requires specialized primers. 
RETARDS FLAME
Purethane® is certified by Lloyds Register Of Shipping as ‘Coating Having Low Flame Spread Characteristics’.
