Polyurethane primer outperforms traditional epoxy primers
Spectracron AdvantEdge HPP primer from PPG is a polyurethane primer that breaks new ground in the product category, capable of delivering greater corrosion resistance, edge performance and chip resistance than other available polyurethane and traditional two-component epoxy primers. For steel and ferrous substrates in heavy-duty equipment (HDE), general finishes and transportation applications, Spectracron AdvantEdge HPP primer offers improved performance capabilities while building new efficiency into your priming process.
How? Here we look at the benefits and explanation as to why Spectracron AdvantEdge HPP primer is different—a polyurethane primer like no other.
For years, two-component epoxy primers have been recognised as the industry standard for quality control and corrosion protection for heavy-duty equipment, general finishes and transportation applications.
The reliance on two-component epoxies by industry OEMs and their approved outsourcers has historically been driven by epoxy’s proven effectiveness in meeting industry standards for corrosion resistance, as well as their comparatively low cost and ease of use.
Polyurethane primers, meanwhile, have offered users a speedier alternative, typically with better topcoat compatibility and faster wet-on-wet application. But a trade-off was required, as polyurethane primers have traditionally offered less robust corrosion resistance.
