New DTM Coating Offers Corrosion Resistance
A new one-layer direct-to-metal coating launched by PPG (Pittsburgh) was reportedly designed to perform in the manner of primer-topcoat systems.
Its SPECTRACRON SPM Series DTM monocoat is described as a one-component coating meant to help prevent corrosion on heavy-duty, transportation, agricultural and construction equipment.
According to the manufacturer, the Spectracron SPM coating was engineered for direct application to pretreated metal substrates while providing corrosion resistance said to be comparable to traditional two-component primer-topcoat systems.
The proprietary high-solids, high-gloss formulation also enables the coating to be applied over pretreatment chemistries such as iron-phosphate, zinc-phosphate and zirconium at supplier-recommended weights, it said.
Scott Laney, PPG product manager, liquid coatings, touted the coating's ability to protect metal with a single-component coating while offering several other benefits for original equipment manufacturers (OEMs).
“Spectracron SPM coating can help OEMs cut production space requirements, inventories and labor costs while improving throughput by eliminating the need to apply primer during the coating process,” he noted.
Laney added that flash times and cure temperatures for the new coating are similar to those commonly associated with current urethane topcoats, which should eliminate concerns about fast wet-on-wet application times and enable the coating to work without constraints on existing paint lines.
