Kujioo Laboratory provides a wide range of testing services. All of our standard tests follow strict guidelines layed out in ISO, ASTM, NACE or CSA standards. Our lists of standard tests are:
Adhesion to Steel/Existing Coating (ISO 21809-3): Used to evaluate the adhesion of a coating system to the underlying steel substrate or the adhersion of a new coating system to an existing coating.
Adhesion Pull off (ASTM D4541 or ISO 4624): Used to evaluate the adhesion strength of a coating system when being pulled off from the metal substrate.
Autoclave (NACE TM 0185): Used to evaluate performance of an internal lining by exposing coating systems to test consitions similar to field conditions including pressure, temperature and gases.
Cathodic Disbondment (CSA Z245.20, CSA Z245.30, ASTM G8, ASTM G42): Is used to evaluate adhesion loss of a coating caused by electrochemical reactions when a negative electrical potential is applied to coated steel structures in cathodic protection systems.
Coating Porosity (CSA Z245.20 Clause 12.10): Used to examine microstructure of a coating to determine if a coating is too porous that may compromise coating performance.
Corrosion Rate Measurment:
Corrosion Under Insulation (Houston Pipe Method): To evaluate coating performance when being exposed to heat, moisture and salt under an insulation.
Differential Scanning Calorimetry (DSC) (CSA Z245.20 Clause 12.7): Used to measure glass transiion temperatures of a coating and monitor coating cure percentage.
Electrochemical Impedance Spectroscopy (EIS) (ISO 16773): To evaluate the barrier property of a coating when being exposed to a bring solution.
Falling Sand Abrasion Resistance (ASTM D968): Test is performed to evaluate the resistance of organic coating to abrasion produced by abrasive sand falling onto coating applied to a plane regid surface, such as metal or glass panel.
Flexibility (CSA Z245.20, CSA Z245.30, ASTM D522): Covers the determination of the resistance to cracking of attached organic coating on flexible substrates, such as sheet metal or rubber-type material. It is used to determine stress on an exterior pipe coating and the chance of cracking under cold temperatures.
Fourier Transform Infrared Spectroscopy (FTIR) (ASTM E1252 & ASTM E168): This test is used to identify different types of coatings for coating analysis and monitor curing process for some specific coating systems.
Holiday Detection (NACE RP0188 & ASTM D5162): A method to determine discontinuities or holidays in coating material which are typically invisible to visual inspection.
Impact Resistance (CSA Z245.20, CSA Z245.30, ASTM G14, ASTM D2794): Evaluation of the resistance to little rocks during backfill or mechanical impact during handling for pipeline exterior coatings, to evaluate the resistance to a dent for automotive exterior coatings.
Interface Contamination (CSA Z245.20 Clause 12.9): To estimate the percentage of non-steel contaminations on a steel substrate, which may affect the adhesion of a coating to the steel substrate.
Peel Adhesion (CSA Z245.21 Clause 12.5): Used to determine the adhesion of a coating to a metal substrate by the application of a constant force (weight).
Pencil Hardness (ASTM D3363): Used to evaluate the resistance of a coating to scratches.
Shore-D Hardness (ASTM D2240): Used to measure the hardness of a cured coating, could be used as an indication of curing in the field.
Solvent Rub (ASTM D4752): Used to evaluate the resistance of a cured coating to a certain solvent, could be used as an indication of curing in field.
Taber Abrasion (ASTM D4060): The purpose of the taber abrasion test is to evaluate coating resistance to mechanical abrasion in accordance with ASTM D4060 "Standard Test method for Abrasion Resistance of Organice Coating by the Taber Abraser".
Weathering Testing (ASTM B117 Salt Spray, ASTM D4587 QUV): Used to evaluate coating performance when being exposed to conditions in nature such as humidity, UV light and salty water.
Wet Adhesion (CSA Z245.20, CSA Z245.30): A hot water soak used to determine the adhesion of coating to substrate while submerged in hot water.
