Request InfoMaster Bond Inc.Master Bond Inc. has introduced a two-component epoxy adhesive, sealant and coating that provides good chemical resistance and high thermal stability. EP21ARHT-1 offers long-term resistance to fuels, oils, ethanol, lubricating compounds and active organic solvents. It can withstand long-term exposures to strong mineral acid solutions and vapors at temperatures of 200 °F and above. The epoxy is 100% reactive and does not include solvents or diluents. It also has a 2:1 mix ratio by weight and cures at room temperature. Designed to withstand thermal shock and abrasion, it acts as an electric...See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase April 2024 IssueIntlvac PARMS for Sputtered IR FilmsThe Nanochrome IV PARMS produces dielectric thin film layers by reactive magnetron sputtering with final reaction and film densification at the substrate surface using a high current, low energy ion...Photonics Showcase September 2023 IssueBullseye® Apodizing FiltersBullseye® Apodizing Filters radially modify beam distribution in optical systems.
