Sunrez Corp, founded in 1986, specializes in the formulation and application of ultraviolet (UV) cure composite materials. These single component systems- available as resins, putties, or pre-impregnated fiberglass repair patches- remain workable indefinitely and cure only upon exposure to UV light. This enables easy handling across a wide range of temperatures, humidity levels, and field conditions, followed by rapid, on-demand curing.

Sunrez Corp has focused on infrastructure rehabilitation efforts and has led the way in UV cure resin systems in both Cure-In-Place-Pipe (CIPP) and the Wind energy sector. Sunrez has increasingly applied its knowledge of composite materials, coatings, and fabrication technologies to programs in support of the US military that range from increased weather resistance, lightweight armoring materials and down-range. Our formulations are no VOC, no HAP and non-flammable for improved worker safety, easy shipping and reduced emissions.

NAVSEA has evaluated Sunrez UV cure materials and issued drawing NAVSEA 630-9014545 “Repair Patch Composite Ultra-Violet Cured, Installation and Details” to guide proper handling and installation under the Phase 1 drawing package. Additional drawing packages and expanded use cases are expected to be released soon.

Sunrez materials provide end users with a versatile solution for repairing corrosion, cosmetic damage, cracks, sealing, pipe wrap, bulkhead repair, and more. They bond effectively to a wide range of substrates including aluminum, steel, copper-nickel, composites, and some plastics.

Problem Statement:

Coast guard assets experience damage and corrosion and fast, straightforward repairs not requiring hot work and corrosion protection are needed
