US Classification:

526 64, 526 88, 526918, 422132, 422135, 422137

Abstract:

A process for producing polymer and more particularly adhesive using a recirculating loop reactor. In one embodiment the reactor includes one or more mixers to mix feed stock with the polymerized material recirculating in the reactor. In another embodiment a planetary roller extruder (PRE) may be used for this purpose. In still another embodiment, a combination of one or more static mixers and one or more PREs may be used.

Appl. No.:

12/838085

Inventors:

Mark A. Lewandowski - Fort Gratiot MI, US
Deborah Anne Chrzanowski - Corunna, CA
Paul E. Rhude - Fort Gratiot MI, US

Assignee:

Intertape Polymer Corp. - Bradenton FL

International Classification:

B32B 7/12
B32B 15/01

US Classification:

428343, 428 401, 428354

Abstract:

Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a lipophilic agent, a flocculating agent, or combinations thereof. The edge coating provides the tape with enhanced masking ability by preventing paints, varnishes, paint strippers, and other coating compositions from infiltrating the tape substrate or the interface between the tape and an adherend.

Jul 29, 2003

Appl. No.:

10/629467

Inventors:

Mark Lewandowski - Marysville MI, US
Jeffrey Parker - East China Township MI, US
Daniel Fenner - St. Clair MI, US

International Classification:

H01J001/62

US Classification:

313509000

Abstract:

A method for screen or rotary screen printing EL lamps comprising front and rear electrodes, a phosphor layer and a dielectric layer. The layers are arranged in a pyramidal shape such that the front electrode has the largest dimensions and the rear electrode has the smallest dimensions. The phosphor layer and dielectric layer have smaller dimensions than the front electrode and the same or different dimensions as each other. The rear electrode has smaller dimensions than the dielectric layer. Preferably, the phosphor layer is screen printed on the front electrode before the front electrode is cured. Preferably, the dielectric comprises an ultraviolet curable solvent-based hybrid ink.

Assignee:

CENTRAL PRODUCTS COMPANY - Bradenton FL

International Classification:

C08F 118/02

US Classification:

526319000, 264211240

Abstract:

A process including the steps of: providing a planetary roller extruder having a plurality of compounding sections including a main spindle surrounded by and intermeshed with a plurality of planetary spindles; introducing monomers and initiator into a first compounding section; producing a homogeneous composition; heating the composition to initiate free-radical polymerization; introducing monomers and initiator into one or more of the remaining compounding sections and continuing the polymerization; discharging the polymerized composition; and optionally, taking a portion of the composition discharged from the planetary roller extruder and returning it to the first compounding section.

Abstract:

A pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing. A method for constructing a member for undersea deployment is provided, which comprises providing at least one tubular member, winding a wire reinforcement about the tubular member(s); and winding a corrosion-resistant filament-reinforced material over the wire reinforcement; and coating the filament reinforced member(s) with a layer of extruded polymer.

Inventors:

Mark A. Lewandowski - Fort Gratiot MI, US
Deborah Anne Chrzanowski - Ontario, CA
Paul E. Rhude - Fort Gratiot MI, US

Assignee:

INTERTAPE POLYMER CORP. - Bradenton FL

International Classification:

B05C 11/00

US Classification:

118504

Abstract:

Disclosed is a tape that includes a substrate having an adhesive layer applied thereto, and an edge coating applied to a masking edge of the tape. The substrate and the adhesive, together, define a first and a second masking edge of the tape. The edge coating includes a flocculating agent that is a polyvalent metal salt or an ionic polymer. The edge coating improves the ability of the tape to provide a sharp mask line after a paint, a varnish, a paint stripper, or other coating composition is applied to a surface where the tape is adhered.
