Title
(EN) SPRAYABLE POLYURETHANE BASED PROTECTIVE COATING
(FR) REVÊTEMENT PROTECTEUR PULVÉRISABLE À BASE DE POLYURÉTHANNE
Abstract
(EN)
A sprayable polyurethane based reaction system for forming a protective coating in industrial containers includes a first component and a second component, each having a viscosity less than 1500 cP at 25 ºC. A difference between the viscosities of the first component and the second component within a temperature range of 60 ºC and 80ºC is from -150 cP to 150 cP. The first component is a reaction product of a polyol component that includes a first butylene oxide propylene oxide copolymer polyol having a polyoxybutylene content of at least 50 wt% and an isocyanate component that includes at least one polyisocyanate. The second component has a second butylene oxide propylene oxide copolymer polyol having a polyoxybutylene content of at least 50 wt%. At least one selected from a group of the polyol component and the second component includes a primary hydroxyl containing polyol.

Cette invention concerne un système réactionnel pulvérisable à base de polyuréthanne destiné à former un revêtement protecteur dans des conteneurs industriels comprenant un premier composant et un second composant, ayant chacun une viscosité inférieure à 1500 cP à 25°C, la différence entre les viscosités du premier composant et du second composant dans une plage de températures de 60 à 80°C étant de -150 à 150 cP. Le premier composant est le produit réactionnel d'un composant de polyol qui comprend un premier polyol de type copolymère d'oxyde de butylène-oxyde de propylène ayant une teneur en polyoxybutylène d'au moins 50 % en poids et d'un composant isocyanate qui comprend au moins un polyisocyanate. Le second composant comprend un second polyol de type copolymère d'oxyde de butylène-oxyde de propylène ayant une teneur en polyoxybutylène d'au moins 50 % en poids. Au moins un composant choisi dans le groupe du composant de polyol et du second composant comprend un polyol contenant un hydroxyle primaire.
