Questions & Answers
Is this suitable for setting firearms optic ring screws? Expert Answer

No. I would recommend using Blue Loctite. Unfortunately, we do not carry it, but it would be the best option for securing scope rings.

Product Info for Loctite 3gm Prism 411 Clear Toughened 442-41104

Our 3M White Prism 411 Acrylic Sealant is made from acrylic copolymer and has a molecularly cross-linked structure. This ensures that the adhesive performance remains unchanged when exposed to great pressures and great heat. The low viscosity and excellent tensile strengths allow it to be used in a broad temperature range, making it suitable for use in a wide variety of applications. It exhibits excellent separation properties, making it suitable for sealing around holes and apertures. It also provides a broad temperature resistance, making it useful in seal, gasket, and vibration repair applications. Its unique two-part construction avoids the disadvantages of single-component sealants, such as the long cure times and poor impact resistance of single-component sealants, such as those used in gas cylinders.image
