What Sunrez does

Sunrez Corporation is a privately held specialty chemicals manufacturer founded in 1986 and headquartered in El Cajon, California, that develops and sells light-curing (UV-cure) resin compositions for the composites industry. The company's core technology centers on proprietary photo-initiator systems that polymerize polyester, vinyl ester, urethane, and acrylic resin formulations upon exposure to UV-A light in the 380-410nm wavelength range, achieving cure in seconds at ambient temperatures from -20°F to 120°F. Its product portfolio comprises UV cure resins (including styrene-free, non-hazmat formulations), thickened UV cure putties for repair, custom UV cure prepregs combining thickened resin with fiberglass sheets (2-60 inch widths, unlimited lengths, multiple fiberglass architectures), and a dedicated LED Cure product line.

The company serves industrial composite manufacturers and repair operators across a horizontal set of verticals, including wind turbine blade repair, marine restoration, pipe relining, ballistic panel fabrication, and consumer composite products such as bathtubs and surfboards. Performance claims versus traditional MEKP peroxide curing include up to 95% reduction in styrene emissions, up to 10% improvement in physical properties in laboratory tests, and thick-wall fiberglass parts fully cured in under five minutes. The one-part system design eliminates metering, mixing, and pot-life constraints associated with two-part peroxide systems.

Sunrez operates a direct-sales, contact-based commercial model with no public pricing, custom order configuration, and worldwide shipping enabled by non-hazmat formulations. The company is bootstrapped with 1-10 employees, no disclosed institutional funding, and no parent company; it appears to be founder- and management-owned. Distribution is single-channel direct to industrial buyers, with marketing conducted primarily through the corporate website (sunrez.com).

Core offering

Sunrez manufactures and sells UV-cure (light-cure) resin compositions — polyesters, vinyl esters, urethanes, and acrylics — formulated to polymerize rapidly under UV-A light exposure at ambient temperatures. The portfolio also includes UV-cure putties for repair applications and custom-built UV-cure prepregs combining thickened resin with fiberglass reinforcement. Products are sold as finished chemical goods to industrial composite manufacturers and repair operators.

Product overview

Sunrez offers a unified portfolio of light cure products centered on UV cure technology for composite manufacturing and repair. The core offerings include UV cure resin (in polyester, vinyl ester, urethane, and acrylic formulations), putty, prepreg (fiberglass-reinforced sheets), and LED cure products. These products share a common UV-A light curing mechanism that enables rapid cure at ambient temperatures ranging from -20°F to 120°F, with cure times measured in seconds to minutes. The portfolio serves diverse applications including renewable energy repair, pipe relining, marine restoration, and industrial composite fabrication.
