The market’s type taxonomy separates adhesive fillers into epoxy‑based, polyurethane, silicone, acrylic, and hybrid families, each with distinct performance envelopes. Epoxy‑based systems dominate with an estimated 45 % share, owing to superior shear strength, chemical resistance, and the availability of two‑component formulations that enable tailored cure schedules. Within this family, two‑component epoxy accounts for the bulk, while single‑component epoxy offers rapid set‑up for field repairs. Polyurethane fillers, representing roughly 25 % of volume, are valued for flexibility, impact absorption, and excellent adhesion to low‑energy substrates; they are further divided into moisture‑curing and isocyanate‑based variants. Silicone fillers, contributing about 15 %, provide high temperature stability and low modulus, making them suitable for sealing and vibration damping in electronics and aerospace. Acrylic fillers, at 10 %, are chosen for quick‑drying, low‑odor applications such as interior trim and consumer goods. The remaining 5 % comprises hybrid blends that combine epoxy and polyurethane chemistries to balance strength and elasticity, reflecting ongoing R&D aimed at niche performance gaps. This type‑based market taxonomy clarifies competitive positioning and informs product‑development roadmaps.
