Abstract

ADESIVO TERMOFUSÍVEL. A presente invenção se refere, de uma maneira geral, a adesivos termofusíveis úteis em aplicações industriais, tal como artigos que se ligam, por exemplo, a caixas de papelão, peças, plásticos, encadernação, fabricação de móveis e para aplicação em embalagens próprias para o congelamento de alimentos. A formulação compreende uma resina, um oligômero (cera) com ponto de amolecimento entre 100 e 120°C e um copolímero de etileno e acetato de vinila (EVA), possuindo, preferencialmente um teor de acetato de vinila igual ou superior a 28% e índice de fluidez igual ou superior a 800g/10 mm. Considerando-se que a adesivo termofusivel da presente invenção apresenta temperatura de amolecimento entre 100 e 115°C, e que a temperatura de aplicação do adesivo da presente invenção varia entre 120 - 140°C, a diferença entre a temperatura de aplicação do produto e seu ponto de amolecimento é entre 20 e 30°C.THERMOFUSE STICKER. The present invention relates generally to hot-melt adhesives useful in industrial applications, such as articles which bind, for example, to cardboard boxes, parts, plastics, binding, furniture making and for application in packaging suitable for the freezing of food. The formulation comprises a resin, a softening point oligomer (wax) between 100 and 120 ° C and an ethylene vinyl acetate (EVA) copolymer, preferably having a vinyl acetate content of 28% or greater and fluidity index of 800g / 10 mm or more. Since the hot melt adhesive of the present invention has a softening temperature between 100 and 115 ° C, and the application temperature of the adhesive of the present invention is between 120 - 140 ° C, the difference between the application temperature of the product and Its softening point is between 20 and 30 ° C.
