Performance of wood impregnated with alkoxysilanes
(REHABEND, 2016-05-24)
The wood, very heterogeneous and complex material, changes its volume by water absorption or desorption causing swelling or shrinkage and also it can be degraded both by action of microorganisms and fire; the above-mentioned ...
Barnices antifúngicos hidrorrepelentes para la protección de maderas de baja densidad
(SAM CONAMET, 2016)
Se formularon barnices, en los cuales se dispersó sílice de diatomeas de bajo índice de refracción, para la protección de paneles de Pinus ponderosa estacionados durante 6 meses a 25±1 ºC y 65±2% HR; los barnices estuvieron ...
Dimensional stability, fire performance and decay resistance in wood impregnated with alkylalkoxysilanes
(2013-11-20)
The wood, very heterogeneous and complex material, changes its volume by water absorption or desorption causing swelling or shrinkage and also it can be degraded both by action of microorganisms and fire; the above-mentioned ...
Decay resistance and dimensional stability of Araucaria angustifolia using siloxanes synthesized by solegel process
(Elsevier, 2013-05-16)
Solid wood specimens of Araucaria angustifolia were impregnated with alkoxysilanes hydrolyzed and
condensed “in situ” by the solegel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane and aminopropyl ...
High solids, one coat paints based on aliphatic epoxi resin siloxanes for steel protection
(Elsevier, 2014-05-01)
This research involved the design of high-solids, one-coat paints for the protection of metal structures
with low maintenance requirements. The main paint components were: (i) an aliphatic epoxy resin
cured with an ...
Impregnación de maderas de baja densidad con hidrofugantes organosilícicos
(2017)
En este trabajo se estudiaron las propiedades de madera de Araucaria angustifolia modificada químicamente por impregnación con alquilalcoxisilanos con diferente longitud de cadena hidrocarbonada, hidrolizados y condensados ...
Uso de nanopartículas para la protección contra el deterioro de madera patrimonial
(Coibrecopa, 2017)
La madera, por su composición química, es muy susceptible a la acción de agentes bióticos y abióticos: se pueden mencionar como los tres principales, hongos xilófagos, humedad y fuego. La intensidad de las alteraciones ...
Pinturas híbridas de terminación sobre fondos anticorrosivos de zinc modificados
(Atipat, 2013-10-01)
Las pinturas basadas en zinc metálico presentan una mayor eficiencia contra la corrosión en relación con otros recubrimientos. Sin embargo, éstas necesitan generalmente una pintura de terminación ya sea para conferirle al ...
Siloxanes synthesized in situ by solgel process for fire control in wood of Araucaria angustifolia
(Elsevier, 2013-10-10)
Panels of Araucaria angustifolia were chemically modified with alkoxysilanes, hydrolyzed and condensed
“in situ” by the sol–gel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane (A),
aminopropyl ...
Hybrid finishing coatings applied on laminar zinc primers
(American Chemical Society, 2013-05-29)
Hybrid finishing coatings were formulated with several film-forming materials and reinforcement fibers. In all cases, the same tri-pigmented epoxy-polyamide coating based on laminar zinc was used as primer. The results ...
