To determine the protective coating spray drying (fog) characteristics of new ASTMD7868 standard practice
According to the China coating procurement network small make up to know, recently, a new ASTM international standards will be used as confirmed that the manufacturer claims such as paint, coating material inherent in spray drying characteristics. ASTMD7868 standards, to determine the protective coating spray drying (Fog) characteristic of practice (PracticeforDeterminingtheDryFall (Fog) PropertiesofProtectiveCoatings), industrial protective coating by D01.46 subcommittee (SubcommitteeD01.46 onIndustrialProtectiveCoatings) established, belongs to the ASTM international committee under this subcommittee D01 paint and coatings, materials and related applications committee.
According to the KTA - BillCorbett Tator company vice President, spray drying coating has been in use for decades, by the paint manufacturers produce and sell all over the world. Overly dry spray coating is designed to spray particles have been dry when landing to the horizontal plane through the air. This spray particle can not damage the surface of the case was brushed off, suck or wash away.
ASTMD7868 standard being developed in used in cannot be used to spray coating project prior to the start of the spray drying characteristic of coating quality evaluation. In addition, new practices will be used to assess when under the condition of higher temperature, the coating will shown the characteristics of spray drying, parked cars such as the sun.
