Low-Expansion Epoxy for Semi-Precious Stone Seam Filling – 5090 / D30M-BS
Overview
Product Description
Low-Expansion Epoxy for Semi-Precious Stone Seam Filling – 5090 / D30M-BS is specially engineered for agate, onyx, and composite semi-precious stone slabs. Its low expansion and low internal stress formulation prevents panel warping while delivering seamless joint filling with no tactile feel after curing.
Product Description
5090 / D30M-BS is a professional epoxy system developed for seam filling and bonding of semi-precious stone slabs. The formulation focuses on dimensional stability, extremely low expansion, and uniform curing behavior to avoid slab deformation. Once cured, the filled seams remain smooth and undetectable by touch, meeting the high aesthetic standards required for luxury stone applications.
