Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Wettability and bonding quality of exterior coatings on fast-growing wood surfaces were studied. Samples of air-dried flat-grained (tangential surface) and edge-grained (radial surface) pattern of jabon (Anthocephalus cadamba) and sengon (Paraserianthes falcataria) woods were used. Before application of exterior coatings, the surfaces of the lumber samples were sanded. To provide wood surfaces with various degrees of roughness, abrasive papers of 120, 240, and 360 grits were used for the surface preparation. The wettability of two exterior coatings (water-based acrylic and oil-based alkyd varnishes) on the sanded wood surfaces was measured using a sessile drop contact angle method. The Shi and Gardner (S/G) model was used to evaluate and compare the wettability of the surface coatings on the wood. The sanded wood samples were coated with the two coatings (two layers each). Bonding quality of the coating layers was measured using a crosscut tape test method. Experimental results show that constant contact angle change rate (K value) of the S/G model decreased as the grit number of abrasive paper increased. This indicates that the wettability decreased as the roughness of the surface decreased (surface becomes smoother). There was no evidence of differences in wettability between tangential and radial wood surfaces. The oil-based alkyd coating generated better wettability compared to the water-based acrylic. The crosscut tests showed that the bonding quality of the coating films on both jabon and sengon wood decreased as the surface became smoother. The sengon wood compared to jabon wood provided better coating wettability and bonding quality. Wettability in terms of the K values was a good indication for determining the bonding quality of the two varnish layers.

These joints are the most important bonds in a product because failure can be catastrophic to the product’s structure and function. When a product is exposed to vibration, shock, chemicals, temperature deviations, or other types of weakening or destructive agents within specified tolerance levels, a properly applied structural adhesive should remain securely bonded.

RevêtementsIndex. décimale : 667.9 Revêtements et enduits Résumé : Many challenges face today's coatings formulators. Some of these challenges involve removing cost from a coating formulation or improving performance but many are related to producing coatings with improved environmental profiles. Lowering volatile organic compound (VOC) levels in architectural and industrial coatings is a chief concern in many new product development and reformulation projects. Balancing good performance and low VOC is critical, as a low-VOC coating with poor performance is of little value. Coatings formulators and end-users are provided with several technology options to address the desire for lower VOC including the use of solventborne coatings with high solids or VOC-exempt solvents (such as acetone or t-butylacetate), powder coatings, and waterborne technologies. Waterborne acrylic latex technology, in particular, offers a number of advantages such as low toxicity, lower risk of fire from handling flammable solvents, easy one-component use, easy and safe cleanup with water, and less hazardous disposal. However, many latex coatings still utilize a significant level of coalescing solvents to aid in film formation, so the challenge of going to even lower VOC levels is still present in many applications currently using or moving towards waterborne latex coatings.
