Hot Melt Adhesive Wire Rod Coater

The hot-melt adhesive wire-wound drawdown bar transfers coating material by means of a metal rod wound with stainless steel wire, with the wire diameter determining the wet film thickness. After heating to melt the solid colloid, it is evenly coated onto the substrate, used for simulating hot-melt adhesive coating processes and quality control in the laboratory.
Selection
Select the wire diameter specification based on the surface characteristics of the substrate, and consider the viscosity of the hot melt adhesive to match the winding gap of the wire rod. Maintain a stable coating speed and ensure the preheating temperature reaches the melting point of the adhesive. Clean and maintain the wire rod to avoid residue, as environmental temperature affects the curing effect of the coating.
