Nuts N' Bolts® 431

Tuffbond® 305 is a modified epoxy adhesive that provides a very fast room temperature cure. Tuffbond® 305 exhibits very good moisture chemical and heat resistance. This very fast cure epoxy adhesive is specially formulated for rapid in-line assembly of loud speakers. Tuffbond® 305 is also recommended for bonding metals, wood, ceramics, etc., and can be used for potting and encapsulation of electrical and electronic components.

Tuffbond® 394 is a single component, high temperature resistant, heat activated epoxy. It cures to a high-performance thermoset system with excellent adhesion properties to a wide variety of substrates. Tuffbond® 394 will change from amber-yellow to a reddish brown upon cure. Bonding the voice coil to the cone has been a challenge for engineers, specifically when the adhesive temperature resistance requirement is above 200°F (93°C). Two component epoxy was commonly used for this application, but limitations such as mixing ratio, cure speed, potential solidification in equipment and the need for equipment flushing solvents have made Tuffbond® 394 more practical.

Dripstop® 923 is a single component, paste-like anaerobic pipe sealant compound, which contains Teflon®. The product cures when confined in the absence of air between close fitting metal surfaces. This industrial grade sealant develops controlled low strength to facilitate disassembly. Certified to NSF/ANSI Standard 61 for use in commercial and residential potable water systems not exceeding 82°C (180°F). Dripstop® 923 is recommended for sealing metal tapered pipe threads and fittings up to 2 inches (5cm) NPT for industrial applications in the chemical processing, petroleum refining, pulp/paper, waste treatment, textile, utilities/power generation, marine, automotive, industrial equipment, gas compression and distribution industries. It is also recommended for industrial plant fluid power systems.

Nuts N’ Bolts® 429 is a single component anaerobic thread locking adhesive. Nuts N’ Bolts® 429 is a high-strength adhesive for locking and sealing large bolts and studs 1inch and larger diameters. Curing occurs only when adhesive is confined between mating surfaces. The cured adhesive is suitable for temperatures up to 300°F (149°C) and exposure to most solvents. Nuts N’ Bolts® 429 meets the requirements of ASTM D5363 (AN0211) which replaced MIL-S-46163A (Type I Grade L) specifications.
