Siloxanes synthesized “in situ” by sol-gel process for fire control in wood of Araucaria angustifolia

The performance in laboratory tests can be explicated according the reactivity of the alkoxides. The results support the conclusion that the best fireproof efficiency was observed in woods treated with the alkoxide B, followed by those modified with the mixture C and the alkoxide A, in this order; the results also indicates that as weight gain increased the performance of impregnants against fire.
