The melted viscosity is the viscosity of a hot melt adhesive that has been melted. The melted viscosity is measured with a B-type rotational viscometer (made by Brookfield Engineering Laboratories) by measuring the viscosity at the optimum usage temperature. Generally speaking, this indicates the viscosity between 140 and 160°C for a product with a low viscosity and the viscosity between 160 and 180°C for a product with high viscosity.
