'Hot set" adhesives made with Methocel (left) remain on the surface to be bonded—without Methocel (right) the hot adhesive penetrates the board.
METHOCEL
HEAT GEL WITH KEEPS ADHESIVES IN PLACE Superior synthetic gum gels when heated to keep adhesives from penetrating laminate materials Methocel® (Dow methylcellulose) puts nature in reverse by gelling in heat, remaining viscous in cold. Even the temperature at which it gels may be determined by the viscosity type used—there are nine from which to choose. The value of this unique Methocel characteristic in adhesives is obvious. Leather pasting formulations, "hot set"'phenol-formaldehyde glues or any other adhesive used during hot pressing conditions need and use Methocel to advantage. Even cold-setting glues use Methocel for dependable viscosity control. Colorless, odorless, inert and remarkably stable solutions of this gum are also widely used as a stabilizer, thickener, suspending agent, hinder and film former.
