Title
(EN) A ONE COMPONENT MOISTURE-CURABLE POLYURETHANE ADHESIVE COMPOSITION FOR ROOFING APPLICATIONS
(FR) COMPOSITION ADHÉSIVE DE POLYURÉTHANE DURCISSABLE À L'HUMIDITÉ À UN CONSTITUANT POUR DES APPLICATIONS DE TOITURE
Abstract
(EN)
A liquid, one component moisture-curable polyurethane adhesive comprising the reaction products of a polyisocyanate with a hydroxyl-terminated polybutadiene, and optionally additives and one or both of a polyester polyol and a polyether diol. In some embodiments the adhesive can be solvent free and have a high solids content of 85% or greater. The adhesive finds use in bonding roofing membranes to roofing deck substrates. It is effective and does not require specialized equipment to apply. It can be applied to only the roofing membrane, only the roofing substrate or to both as desired. In some applications the adhesive initially cures forming a thin skin with liquid adhesive below which permits for easy manipulation of the roofing membrane on the roof substrate. Once properly positioned light pressure breaks the skin and spreads the adhesive between the roofing membrane and the roofing substrate bond the membrane to the substrate.
(FR)
Un adhésif de polyuréthane durcissable à l'humidité à un constituant comprend les produits de réaction d'un polyisocyanate avec un polybutadiène à terminaison hydroxyle, et éventuellement des additifs et un polyol de polyester et/ou un polyéther diol. Dans certains modes de réalisation, l'adhésif peut être exempt de solvant et avoir une teneur en solides élevée supérieure ou égale à 85 %. L'adhésif trouve une utilisation dans la liaison de membranes de toiture à des substrats d'accueil de toiture. Il est efficace et ne nécessite pas d'équipement spécialisé en vue de son application. Il peut être appliqué uniquement sur la membrane de toiture, uniquement sur le substrat de toiture ou sur les deux selon les besoins. Dans certaines applications, l'adhésif durcit initialement en formant un revêtement mince sous lequel se trouve un adhésif liquide, ce qui permet une manipulation aisée de la membrane de toiture sur le substrat de toit. Une fois correctement positionné, une légère pression rompt le revêtement et étale l'adhésif entre la membrane de toiture et le substrat de toiture lie la membrane au substrat.
