In the 1960s a coating system formed by overcoating a molten hot-melt coating with a latex paint was conceived as an answer to a search by the wood siding industry for a primer to improve paint performance on its product. Performance testing, including weather exposure, had a positive outcome, but circumstances prevented commercialization. Thirty years later, the originator of the concept undertook a more thorough investigation. This article is a public a report on coating system composition and performance.
A water-cooled, rotating rack instrument, the Ci4400 Weather-Ometer® has an assortment of common pre-programmed test methods as well as custom test slots.
Dow recently hosted a two-day media event at their Spring House Paint Farm and Collegeville, PA, sites where we toured the exposure farm and testing station, and had exclusive access to the R&D facilities where coatings research projects are underway.
Xenon arc instruments provide realistic weathering testing to determine the long-term effects of sunlight, heat and moisture on the efficiency and functionality of rotor blade coatings.
A team of coatings industry experts worked together for as many as 10 years on the testing and adoption of this standard. The methodology in this new cycle applies not only to automotive coating systems with steel and plastic substrates, but can also apply to aircraft coatings as well as coatings for other industries.
Atlas has announced the 2013 dates for its global Client Education program, with workshops and seminars scheduled throughout the United States and Europe.
Although silicone-modified polyester (SMP) and super-polyester coatings are well-suited for specific applications, they cannot provide the same proven long-term performance as 70% polyvinylidene (PVDF) coatings due to the latter’s superior chemistry.
Atlas Material Testing Technology, a leader in accelerated weathering instruments and weathering testing services, has entered into an alliance with SGS, a leading inspection, verification, testing and certification company, allowing for the expansion of the Atlas 25+ PV module durability test program.
