Water-based paint so safe environmental protection, but why is it so hard to promote?

Water-based paint with water as diluent, do not contain harmful material such as formaldehyde, is a kind of environmentally friendly coatings.
As the strictly on national and local environmental policies, the related technical challenges gradually be rent asunder, and consumer awareness has increased, water-based paint market environment significantly improved, usher in huge opportunities for development.
Newspapers media said more than once, water-based paint is the new trend of future development, in terms of the situation, however, water-based paint market is still not optimistic.
Why is water paint promote up so difficult?
Sum up a number of reasons:
1, the price is high,
water paint the current price is generally higher than the oil paint, many enterprises in order to control the cost, and thus lead to coating of ability in utilization rate is not high.
2, high construction requirements
waterborne wood paint need eight - 35 ℃ temperature, relative humidity - 50 75% of the environment construction. Under normal circumstances is about 20 ℃ temperature and humidity no more than 70% of construction effectively. Too high or too low temperature may cause the coating effect is bad, orange peel, bubble.
3, construction high cleanliness requirements
water paint surface cleanliness requirements of construction materials is very high, because the water's surface tension, make the film produces shrinkage, if can't clean up very clean, non-aqueous impurities mixed with oil, grease, wax, etc, will greatly influence the effect of water-based coating, however.
4, equipment demanding
coating on corrosion coating equipment is big, need to adopt anti-corrosion lining or stainless steel, high equipment cost. Water-based coatings for pipeline corrosion, metal dissolution and scatter particles precipitate, pitting coating, also need to use stainless steel tube.
these reasons largely limits the promotion of water-based paint. But the momentum of development is still rapidly water-based paint. As future policy and technical factors such as push, we believe, water-based paint market share will continue to expand, become the leading coatings market.
