Polynt POLYCOR® 945GA104 Green Polyester Tooling Gel Coat
Categories: Polymer; Thermoset

Material Notes: Polynt Composites Korea tooling gel coats are formulated specifically for mold making. These precision-formulated gel coats utilize selected resins that exhibit high heat distortion to withstand the repeated molding of FRP laminates. None of these products contain lead. They provide a high gloss and hard durable surface. These tooling gel coats are formulated ready-to-spray after the addition of the proper amount of an appropriate methyl ethyl ketone peroxide catalyst. They are formulated to be low in hide so that imperfections can be easily spotted. Read application instructions carefully, because even though manufacturing precautions are used to make tooling gel coat, a misapplication of these products can produce unacceptable results
