Performance characteristic numbers are used, with the following definitions for chemical resistance and wear index - abrasion resistance:Ĥ - Minimal effect or slight change and little repair required.ģ - Some effect noticeable change, and the coating will recover with minimal repairs.Ģ - Moderate effect, performance adversely affected and repairs required.ġ - Poor performance and film failure is imminent and repairs are difficult. Water-borne coatings must be cured in a dehumidified atmosphere and can be assisted with infrared light and good air movement.
45-55% humidity at 70-80 degrees Fahrenheit.Testing was evaluated in an ISO 9000-certified laboratory using the following ASTM test criteria: Chemical Resistance Testing - ASTM D1308 (latest edition), Wear Index - Abrasion Resistance Testing - ASTM D4060 (latest edition).īaseline data for application prior to testing: As a side note, an AWI Letter of Licensing is not a valid term.
If this additional certification is not necessary, all references to AWI QCP Labels, Certificates, or Letter of Licensing, should be removed from the specification. Notes for Performance Characteristics table: 5 of the sell price, whichever is greater. Furthermore, it is intentional that the revised reagent list in CR-1 test method varies from the list above in order to collect and establish new data, allowing for emerging technologies. * Denotes finishing technologies identified by the Window and Door Manufacturing Association (WDMA) as applicable to doors addressed in ANSI WDMA I.S.1A and I.S.6A standards.ĪWI acknowledges the table above as historical data established through industry use of previous AWI standards.
