AL COAT is primarily a tried and true automotive molding stretching inhibitor.
Generally, in the process of profile extrusion molding, molten resin is extruded through a die with a required cross-section shape and cured to continuously make molded parts with a certain cross section. Molten resin shrinks when it is cooled and cured, leaving molding distortion in the finished molded products. To remove this molding distortion, annealing is required.
Thus, conventionally, this required extrusion → rough cutting → annealing → precision cutting, necessitating a substantial amount of man-hours.
AL COAT allows precision cutting at the time of extrusion molding thanks to its stretching inhibiting effect, achieving a reduction in total costs.
Also, steel or other flat plates were applied with adhesive and dried then inserted into molten resin when extrusion molding with conventional stretching inhibitors. This required adhesive application and drying facilities with substantial man-hours. Also, the use of solvent caused environmental concerns.

For AL COAT, adhesive is applied on both sides of hard aluminum in advance.
At the time of extrusion molding, a cross head die is used to insert this product into resin while extruding it. The heat of molten resin melts an adhesive layer, allowing it to be fused with resin. As molten resin cools and cures, the adhesive layer also cools and cures, enabling its adhesion to molding. In this cooling process, this product prevents resin from stretching and distortion when molding.
