Ethyl Silicates with Different Hydrolysis Degree like Non-flammable Impregnating Material for Wood Silicatos De Etilo Con Diferente Grado De Hidrólisis Como Material Impregnante Ignífugo Para Maderas

The wood, like other materials, cannot indefi nitely resist the action of the fi re without undergoing deterioration. In this work, low-density wood panels were impregnated with partially hydrolyzed ethyl silicates The results obtained in laboratory, with different degree of penetration and retention of the impregnant material, showed through tests in a Horizontal-Vertical Cabinet, a LOI Chamber and an Inclined Tunnel a high fi re retardant effi ciency.
