Hi-Tec Spray’s two-pack polyurethane spray system technology and Graco’s Merkur 30 or 40:1 ratio pumps offer significant benefits to contractual joiners and furniture makers in particular.
The two-pack polyurethane spray system pump has the advanced feature of mixing clear, top and base coats or full pigments automatically with the catalyst hardener at a consistent ratio of 2:1, delivering a quality mix and only on demand.
As the mix occurs outside the main supply source, product only in transit to the gun (barely 200ml) is discarded when flushed through by solvent at the flick of a lever.
The pump also employs the more sophisticated air mix technology rather than air spray which provides greater transfer efficiency with less waste and an outstanding finish.
Graco’s Merkur pump is suitable for single component application whether the material be water based or solvent based. Using low pulsation with high output fluid delivery, the air-assisted, airless spray technology employed ensures excellent finish quality with high material transfer efficiency and fast production rates.
