ABSTRACT:
A process for chemically bonding a screen fabric material to a frame structure for serigraphic printing purposes. The bonding or fastening process includes, providing a screen fabric material in taut communication to peripheral portions of a frame structure. A cyanoacrylate based adhesive is applied to the screen fabric portions in communication with the frame periphery. A chemically basic catalyst is then brought in contact with the applied cyanoacrylate adhesive to activate or accelerate the anionic polymerization of the applied adhesive for quick curing thereof. The use of methylcyanoacrylate, ethylcyanoacrylate and isopropylcyanoacrylate adhesives are provided for specific end-use purposes. A basic catalyst, in a spray mixture, consisting of aromatic amines is used for quick and easy anionic polymerization of the cyanoacrylate based adhesive. And, a compatible dye for use in conjuction with the cyanoacrylate adhesives is provided for distinguishing the various cyanoacrylate adhesive structures, and to aid in the proper application of the cyanoacrylate adhesives to the screen fabric portions in communication with the frame structure.
