QUALICOAT Requirement for Natural weathering test
Exposure in Florida according to ISO 2810 , The natural weathering test should start in April. Class 1 organic coatings Samples shall be exposed facing 5° south to the horizontal and facing toward the equator for 1 year. 4 test panels per colour shade are required (3 for weathering and 1 reference panel) Class 2 organic coatings Samples shall be exposed facing 5° south for 3 years with an annual evaluation. 10 test panels per colour shade are required (3 per yearRead More …
Tape Test for evaluating coating adhesion
By far the most prevalent test for evaluating coating ”adhesion”is the tape-and-peel test, which has been used since the 1930’s. In its simplest version a piece of adhesive tape is pressed against the paint film and the resistance to and degree of film removal observed when the tape is pulled off. Since an intact film with appreciable adhesion is frequently not removed at all, the severity of the test is usually enhanced by cutting into the film a figure XRead More …
Rapid Testing Methods for Production Control
For some years now, special time-compressed corrosion tests based on recommendations made by European quality associations have become more established. The following are worthy of mention: condensation test, acid and neutral salt spray test, filiform corrosion tests and specific automotive test standards. Despite the demand to speed up tests, testing times of between 40 and 60 days are typical, thus rendering the tests irrelevant as far as real-time production control is concerned. In this regard, rapid innovative corrosion tests areRead More …

Hazardous chemicals in powder coating activities
Triglycidylisocyanurate (TGIC) TGIC is classified as a hazardous chemical and is commonly used in powder coating activities. It is: a skin sensitiser toxic by ingestion and inhalation genotoxic capable of causing serious eye damage. You should check SDSs and labels to determine if the powder coat colors you are using contains TGIC. Electrostatic powder coating containing TGIC are applied by electrostatic process.Workers who may come into direct contact with TGIC powder coatings include persons: filling hoppers manually spraying powder paint,Read More …
Two common types of ventilation in spray painting
Two common types of ventilation used in spray painting are: Local exhaust ventilation captures the overspray and solvent vapour as close to the source of release as possible by drawing the contaminants into a capture hood. They should be fitted with a particulate filtration system to filter overspray. Wherever possible, local exhaust ventilation should be used when a spray booth cannot be used. It may be necessary to use it in combination with other control measures. Information on local exhaustRead More …
Maintenance of spray equipment
You should ensure that the plant and spray equipment used in spray painting or powder coating activities is well maintained, operational and clean. This includes: regular visual checks of equipment and plant, including engineering controls and ventilation systems regular monitoring and testing of ventilation flow rates regular servicing of all equipment and plant procedures for reporting and repairing faulty equipment records of servicing, maintenance, repair and testing of plant and equipment should be kept for future reference. When undertaking maintenanceRead More …

Conditions for Dust Explosions
During powder coating application , the conditions for dust explosions must be paid attention highly to avoid any problem occur . A number of conditions must exist simultaneously for a dust explosion to occur. The dust must be combustible (as far as dust clouds are concerned, the terms “combustible”, “flammable” and “explosible” all have the same meaning and could be used interchangeably). The dust must be dispersed (forming a cloud in air). The dust concentration must be within the explosibleRead More …
