A novel mathematical model is presented on the methylolation of melamine with formaldehyde at 48 ºC and pH 9.0. The model assumes an instantaneous hydration/dehydration of formaldehyde and the methylolation mechanism of ...

In this work, epoxy-loaded microcapsules were successfully synthesized by in situ polymerization in oil-in-water emulsion with poly(melamine-formaldehyde) as shell material and diglycidyl ether of bisphenol F resin as ...

The search for wood base panels more durable and sustainable over time give impulse to medium density panel producers to develop special products much more efficient in relation to humidity behavior. Cost impact is higher ...

Crosslinkable latexes aim to improve the physical properties of coalesced latex films, over levels attainable with thermoplastic latexes, which lackthermal, mechanical and solvent resistance. This work investigated the ...

Nowadays, crosslinkable polymers are highly demanded in applications where improved thermal, mechanical, and chemical strengths are required. Among crosslinkable polymers, those with film forming capability (e.g., coatings ...

There is a great concern about the indoor microbial colonization especially in places that should have high standards of environmental hygiene. Besides, due it shortened the useful life of the coating by discoloration and ...

The use of wood-base panels in humid environments, in general, presents low durability due to contact with water. In order to increase durability and reduce the attack of fungi, studies had been developed using resin with ...

According to ABIPA (2009), Brazil is currently among the major producers of reconstituted wood panels, with one of the main factors for this condition, its climate and its large land area, which allows the cultivation of ...
