What Hapco does

Hapco, Inc. is a privately held specialty chemical and equipment manufacturer founded in 1969 and headquartered in Hanover, Massachusetts. The company formulates thermoset polymer systems — including polyurethanes, epoxies, and silicones — marketed under nine proprietary brands (Di-Pak, Filter-bond, Hapflex, Hapsil, Steralloy, Sympoxy, Tuffalloy, Ultralloy, and Ultraclear), and it designs and builds proprietary metering, mixing, and dispensing equipment under the RAPIDFIL, MINIFIL, RAPIDSHOT, X-series chamber, and X-VAC product names. Its core technical competence is the co-development of formulations and dispensing hardware, sold as an integrated system to industrial OEMs.

Hapco's commercial focus is B2B direct sales to manufacturers in industrial, medical, military, filtration, and food processing end markets. The company's most visible customer base sits in life-sciences filtration, where it is a long-tenured (40+ year) preferred supplier to MilliporeSigma, Pall Life Sciences, and Koch Membranes, principally through its Filter-bond product line used in membrane module assembly. Hapco also serves a broader long tail of customers across its other branded materials and custom formulation engagements. Quality and regulatory positioning includes ISO 9001:2015 certification, RoHS compliance, and TURA (Toxic Use Reduction Act) compliance, supporting qualification for regulated end uses.

The business model is direct B2B sales with quote-based pricing tied to formulation specification, batch size, and equipment configuration. The company supplements direct sales with a distributor network, offers a custom formulations service for tailored compounds, and is led by General Manager Fred DeSimone. Hapco is privately held with 11–50 employees and has not disclosed external funding, acquisition activity, or financial results.

Core offering

Hapco manufactures and formulates thermoset polymer materials (polyurethanes, epoxies, silicone rubbers, epoxy powders) and portable meter-mix dispensing equipment for casting, coating, bonding, potting, and encapsulating applications. The company sells materials under branded sub-product lines (Di-Pak, Filter-bond, Hapflex, Hapsil, Steralloy, Sympoxy, Tuffalloy, Ultraclear, Ultralloy) along with custom formulations, and also designs and assembles dispensing and molding equipment (MINIFIL, RAPIDFIL, RAPIDSHOT, X-Series chambers, X-VAC).

Product overview

Hapco is a manufacturer and formulator of thermoset polymers and dispensing equipment, operating since 1969. The product portfolio consists of three main categories: (1) Materials - thermoset polymer formulations including flexible, semi-rigid, and rigid polyurethanes; epoxies; clear urethanes; silicone rubbers; and epoxy powders. These are sold under branded sub-products including Di-Pak (potting/encapsulation), Filter-bond (filtration adhesives), Hapflex (flexible urethanes), Hapsil (RTV silicone rubbers), Steralloy (flexible/food-grade), Sympoxy (epoxy powders), Tuffalloy (rigid urethanes), Ultraclear (water-clear casting), and Ultralloy (rigid urethanes). (2) Equipment - portable meter-mix dispensing systems (MINIFIL manual, RAPIDFIL digital, RAPIDSHOT handheld gun) and heated pressure/vacuum molding chambers (X-11, X-20, X-60, X-VAC) that eliminate time, waste, and mess in two-component material processing. (3) Accessories - additives, color dispersions, primers, and release agents. All formulations are 100% mercury-free and the company is ISO 9001:2015 certified.
