Filed:

May 18, 2006

Appl. No.:

11/436823

Inventors:

Ruth Bennett - Erie PA, US
Mark Pressley - Cary NC, US

International Classification:

C08L 63/00
C08L 33/00
B65D 83/00
B32B 27/00

US Classification:

525107000, 206229000

Abstract:

Two-part, elastomeric sealant coatings curable at ambient temperature. The sealant contains a radical polymerizable component, an oxidizing agent and a reducing agent, and optionally an epoxy component, polar wax, and/or rheology modifier. The radical-polymerizable component contains 25 to 45 weight percent of alkacrylate monomer and unsaturated phosphorous monomer and 55 to 75 weight percent of an ethylenic unsaturated liquid elastomer polymer having a number average MW of from 3,000 to 9,500 and a backbone Tless than −30 C. The elastomer polymer makes up 32 to 55 weight percent of the sealant and epoxy component makes up 2 to 15 weight percent. The elastomeric sealant coatings provide corrosion protection over the seams and maintain a crack-free surface over a broad temperature range. The sealant coatings are useful for applying over seams of joined metal parts, especially weld seams in the manufacture of automotive unit bodies, doors, floors, hoods, trunks, and trunk lids.

Assignee:

Lord Corporation - Erie PA

International Classification:

C08F27902
C08L 6300

US Classification:

1563314

Abstract:

A two-part, heat stable, peroxide-free adhesive that can be mixed in equal parts with rapid cure for the bonding of plastics and metals has been discussed. Part A of the adhesive contains a polymeric material, an olefinically unsaturated monomer, an acid material, a compound containing a sulfonyl halide group, and a compound containing a transition metal; and Part B contains a polymeric material (preferably a phenoxy resin) and monomer of the same class and a Zn, Cu or Cd metal powder.

International Classification:

B32D 3500
B05D 302
C08L 6302

US Classification:

427140

Abstract:

A primerless method for repairing a substrate surface that includes applying to the surface a curable filler composition that includes (i) an epoxy compound, (ii) a polythiol curing agent, and (iii) a catalyst and then curing the composition. The filler composition can also include a polyamine in addition to the catalyst.

Assignee:

Lord Corporation - Erie PA

International Classification:

C09J 502

US Classification:

1563073

Abstract:

A one-component heat stable, adhesive for metal surfaces such as iron, zinc, copper, cadmium and their alloy will cure upon contact with the metal surface. The adhesive composition includes olefinically unsaturated monomer; at least one phenoxy resin together with other reactive or non-reactive polymers; an acidic material; a compound containing sulfonyl halide group; and a compound containing a transition metal, in particular TiO. sub. 2. The adhesive composition cures rapidly upon contact with a metal surface to form an adhesive bond between the surfaces. The adhesive composition is especially useful as an adhesive for galvanized steel parts subjected to elevated paint curing temperatures.
