Title (EN) ADHESIVE FOR ICE AND WATER BARRIER FILMS
(FR) ADHÉSIF POUR FILMS FORMANT BARRIÈRE À LA GLACE ET À L'EAU
Abstract:
(EN) Ice and water barrier films are provided which comprise an adhesive layer comprising a rubber blend of polyisoprene and a styrene-isoprene-styrene (S-I-S) block copolymer rubber. In some embodiments, the adhesive layer may comprise polyisoprene and the S-I-S block copolymer in a weight ratio of between 70:30 and 88: 12 and the total combined weight of polyisoprene and the S-I-S block copolymer may be between 36 wt% and 51 wt% of the adhesive layer. In some embodiments, the adhesive layer may comprise at least 10 wt% of a plasticizer and between 20 wt% and 60 wt% of a tackifier. In some embodiments, the adhesive layer has a low Tg, typically less than -20°C, more typically less than -40°C, and more typically less than -50°C. In some embodiments, the ice and water barrier film passes the Nail Seal Ability Test performed according to ASTM D1970.
(FR) L'invention concerne des films formant barrière à la glace et à l'eau qui comprennent une couche adhésive comprenant un mélange de gomme de polyisoprène et une gomme copolymère séquencé de styrène-isoprène-styrène (S-I-S). Dans certains modes de réalisation, la couche adhésive peut comprendre du polyisoprène et le copolymère séquencé de S-I-S dans un rapport pondéral compris entre 70:30 et 88:12, et le poids total combiné du polyisoprène et du copolymère séquencé de S-I-S peut être compris entre 36 % en poids et 51 % en poids de la couche adhésive. Dans certains modes de réalisation, la couche adhésive peut comprendre au moins 10 % en poids d'un plastifiant et entre 20 % en poids et 60 % en poids d'un agent poisseux. Dans certains modes de réalisation, la couche adhésive a une Tg faible, généralement inférieure à -20 °C, plus généralement inférieure à -40 °C, et plus généralement inférieure à -50 °C. Dans certains modes de réalisation, le film formant barrière à la glace et à l'eau réussit le test d'étanchéité autour des clous réalisé selon la norme ASTM D1970.
