Good application systems ... (cont.) such issues. Where the application is by spraying, the issue of what equipment to use has slowly resolved itself over the last few years. “Using dedicated waterborne spray gear has become the norm these daysâ€? comments Jason Lynch from Strouds, suppliers of Graco and Binks spray gear. “It is possible to use equipment previously used on solvent based paints but with extreme caution, plastic components such as pump seals, uid hoses and ďŹ lter components absorb solvents, using waterborne through these systems without neutralising or replacing these items may cause contamination issues resulting in post spray warranty issues. We recommend using a pump saver which helps save the spray gear from the corrosive eects water can have if left in the pump or pressure pot.â€? Some may be put off by the cost of shifting to waterborne systems. Using the best gear with
stainless steel parts is the best option. “Using waterbased paint is indeed a dierent system from solvent but it is not as diďŹƒcult as it sounds.â€? comments Chey Brown from DBNZ Coatings, NZ agents for the OECE brand from Sherwin Williams. “The key is a willingness to try out waterbased paint. It is not that hard and with a little practice most spraypainters will be asking what all the fuss was about.â€? This leads to the question of education. “Dealing
with the mental and possibly the dollar barriers (apart from equipment costs, water based vs solvent paint cost is competitive) will see the already huge shift to waterborne continue.� This need for education has seen a number of industry partnerships spring up to address this issue. Strouds for example have good working relationships involving training and R&D with most paint suppliers.
PPG’s Technical Sales Trainer Adrian Armstrong comments. “We have been running trials of recent and good preparation of the wood surface deals with grain raise and leads to good paint coverage and a lower cost per square metre with waterbased paint. Drying times are very good with good hardness as well. Long term water based is the future. It has been interesting to note that the popular look at the moment has been matt and flat finish which has ďŹ tted with the technical stage water based is at. Colour has been a challenge but is being addressed by the industry. After much research and testing we at PPG will soon be launching a new waterbased paint called 2K 500 Amerthane Pigmented to deal with coloured coatings.â€? In speaking with Andrew Hebden from Mirotone NZ Ltd, another leading paint manufacturer in the New Zealand market, he comments. “At Mirotone, we (cont. over page)
