phenolic adhesives are 170 to 230 C. The pressing time is 18 to 12 s/mm for standard PF. resins but today PUFs , and ester-accelerated [31,32], tannin-accelerated , and urea-. drowned PF
Cold-adhesive 5988 R. Special adhesive on the basis of an aqueous styrene acrylic dispersion, which develops a high adhesive power by removing water. Suitable for cold bonding of polystirol foam model and mould parts, is used for the lost foam process and full mould casting. Mask adhesive. Ashland Arofene phenolic resins and adhesivesArofene phenolic resins are used as media saturants providing heat, chemical and water resistance as well as other specialized properties such as a frictional coefficient. They are also used as prepreg resins for laminating applications, as base resins or fortifiers for adhesives or as a resin used to adhere sizing to paper in abrasive applications.
Manufacturers using the shell molding process experience excellent dimensional accuracy, surface smoothness and high production rates using phenolic resin coated foundry sands. The shell molding process involves first creating mold cavities and cores by shaping sand coated with phenolic resin over a not metal form.
