Title
(EN) ADHESIVE AND METHODS OF USE
(FR) ADHÉSIF ET PROCÉDÉS D'UTILISATION
Abstract
(EN) An acrylic adhesive formulation that can be used for various building envelope applications. The adhesive can be coated onto various substrates such as flashing, vapor permeable membranes, vapor impermeable membranes and roofing underlayment's to make them self-adhering. The adhesive can be applied in cold temperatures from 0 degrees Fahrenheit (-18 degrees Celsius) but will maintain integrity at high temperatures without sacrificing the bonding to common construction/fenestration surfaces. The adhesive can include a blend of a plasticizer and an ultra-violet (UV) curable acrylic base polymer, which can be crosslinked upon exposure to a narrow wavelength range of ultra-violet light.
(FR) L'invention concerne une formulation adhésive acrylique qui peut être utilisée pour diverses applications d'enveloppe de construction. L'adhésif peut être appliqué sur divers substrats tels qu'un solin, des membranes perméables à la vapeur, des membranes imperméables à la vapeur et des sous-couches de couverture pour les rendre auto-adhésifs. L'adhésif peut être appliqué à des températures froides de 0 degrés Fahrenheit (-18 degrés Celsius) mais conserve son intégrité à des températures élevées sans sacrifier la liaison à des surfaces de construction/fenestration communes. L'adhésif peut comprendre un mélange d'un plastifiant et d'un polymère de base acrylique durcissable aux ultraviolets (UV), qui peut être réticulé lors de l'exposition à une plage de longueurs d'onde étroite de lumière ultraviolette.
