HMG Paints’ Monothane single-stage, 2k polyurethane topcoat is formulated to be applied directly onto a variety of substrates without the need for a primer. The single coat, gloss finish is suited for mild steel, aluminium, galvanized steel, castings and difficult-to-paint substrates such as uPVC, polystyrene, GRP and sheet-molded composites plastic.
According to the company, most paint jobs can be carried out in a single stage, reducing process times and product usage, and decreased force drying times can further increase paint shop productivity. The process is suited for a variety of applications, including agricultural and construction plants; office hardware and shelving; trailer frames and chassis; garage doors and metal frames; uPVC fascia panels, doors and windows; PVCu fencing; and bicycles. It can be used either as a direct-to-substrate OEM coating or as high-performance touch-up paint for use by distributors and end-users.
The topcoat features resin technology for improved durability and weathering. It also contains adhesion promoters and anti-corrosive pigments for improved bonding to a range of substrates and to prevent rusting on iron and steel. It is available in a high-gloss finish as well as other sheen levels, and in a range of colors.
The topcoat can be applied by airless, air-assisted, conventional gravity and HVLR spray guns, or brush applied, providing coverage ranging from 18 to 24 sq m/L at 25 microns film thickness, depending on color and finish. Surface preparation can be achieved by a solvent wipe or shotblasting, and, since no primer is required, application costs can be reduced and speed throughput increased.
