Polyvinylidene fluoride (PVDF)-based topcoats have long been the choice of architects and specifiers who are seeking superior weatherability.Arkema, Inc. has developed water-based PVDF-acrylic hybrid dispersions to meet the need of resins applied in the field or over temperature-sensitive substrates.
In order to meet the Paris Agreement’s net-zero by 2050 target, wind and solar electricity generation needs to increase by between 72.97-74.7%, according to the 2021 State of Climate Action Report. In order to support this seismic growth, leading edge repair and protection systems play a critical role in extending the lifespan of wind turbine blades and, therefore, supporting a net-zero future for the planet.
Emergence of real-world testing of coatings products to validate the protection levels of assets worldwide is becoming a major issue. Here Sherwin-Williams reveals how the company is committing to a new level of these tests on behalf of its customers.
The ultimate goal of field testing is to evaluate and recommend the best performing preservatives that will offer protection of customer coatings across the widest range of potential environmental eventualities for their end-use products.
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.
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.
