Adhesive/Sealant bonds most plastics.

Press Release Summary:

MRC 04-1348 UV/Visible light curing adhesive/sealant is based on aliphatic urethane acrylate chemistry. It cures in 2 to 5 seconds with UV light to form bonds that are optically clear and resistant to yellowing, moisture, and some solvents. MRC 04-1348 is semi-thixotropic at 25 deg C, cures to 40 to 50 Shore D, and has operating temperature of -40 to 130 deg C. Transparent liquid is suitable for clear bonds to glass or clear plastic.

MERECO MRC 04-1348

UV/Visible Light Curable Adhesive/Sealant for Bonding Most Plastics


Mereco MRC 04-1348 is a part of a new class of Mereco UV/Visible Light curing adhesive/sealants designed to form very high strength bonds to plastics such as polyethylene, polypropylene, polyester, polycarbonate and ABS. It is particularly suited to
plastic laminating applications. Mereco MRC 04-1348 bonds are optically clear, resistant to yellowing, to moisture and some solvents. The light sensitivity of Mereco MRC 04-1348 allows it to be used with UV stabilized, translucent, or colored substrates.
