Waterborne paints for outdoor: the resistance to blocking and the film extensibility

Wood coatings play two basic roles: one is aesthetical as they improve the surface appearance enhancing the wood substrate pattern; the other is protective since wood is sensible to water, light, micro-organisms, insects and other factors and consequently needs surface treatments in order to improve the service life of wooden products.

Speaking about coatings for exterior use, one of the main properties they must develop after drying is the extensibility of the coating film.

Wood is subject to dimensional changes in consequence of the effect of humidity and water in general. These changes vary from wood specie to wood specie, but they last for all the life of the finished product depending on the climatic conditions where it is placed (read more).
