NEXTITE 550 High Viscosity, General Purpose Instant Adhesive

Product Overview

NEXTITE 550 is a high viscosity, high performance instant adhesive engineered for all round performance. It’s all around general purpose formulation makes it ideal for a wide range of applications including bonding plastics, metals and rubbers. Due to its thicker viscosity it allows for bonding on rough, porous and vertical surfaces where other instant adhesives fall short. Perfect for both high strength bonding applications and any fast at home jobs or repairs.

NEXTITE 550 has a high viscosity 1500 CPS at 25°C which provides excellent control during application and ensures precise placement of adhesive. Unlike lower viscosity instant adhesives, it does not immediately run or spread out once applied, allowing the user more working control and reducing mess. NEXTITE 550 cures rapidly, achieving strong bonds on most substrates in approximately 15 seconds. It allows for 0.15 mm of gap filling and is very high strength on close fitting parts.

NEXTITE 550 pairs great with NEXTITE CA-1 Cyanoacrylate Activator allowing you to instantly cure thick beads of adhesive on demand.

NEXTITE CA-1 Cyanoacrylate Activator

NEXTITE CA-1 can be used in conjunction with NEXTITE Cyanoacrylate Adhesives to promote a faster cure and to extend their gap-filling capabilities. Cyanoacrylate Adhesives naturally have limited gap-filling ability, but the use of an activator helps extend this capability by curing the adhesive almost instantly. Using a cyanoacrylate activator it also enables fillets of cured adhesive to be formed if required and can be used to reduce the effects of blooming, which can affect decorative surfaces. CA-1 is particularly effective when bonding porous materials, as the rapid curing prevents the adhesive from soaking in and ensures a stronger more reliable bond.

NEXTITE SP 901 Polyolefin Primer

NEXTITE SP 901 is a surface primer for making polyolefins and other low surface energy surfaces suitable for bonding with NEXTITE Instant Adhesives. It is suitable to prime the notoriously difficult to bond surfaces such as polyethylene, polypropylene and polytetrafluoroethylene (PTFE). NEXTITE SP 901 works well with all of our cyanoacrylate adhesives especially the faster fixture time ones.

Applications and Uses

NEXTITE 550 has been designed as an all round high viscosity instant adhesive. It is ideal for industries and tasks that require a general purpose adhesive with instant bond and high strength. Due to its thicker viscosity it is also ideal for surfaces that have a rough, porous surface as well as vertical bonding

Tools and Accessories

The 50g and 100g bottles are specifically designed to work with a variety of nozzles and tips, so users can adapt the application method without the need to transfer the adhesive into another container. The nozzles come in a variety of internal diameters and lengths for all types of applications. They easily press-fit directly onto the tip of the instant adhesive bottle. The benefit of using alternative tips is that it gives users greater control, allowing only a precise amount of adhesive to be dispensed. They also extend the reach of the bottle, making it easier to apply adhesive accurately in tight spaces or detailed applications.

For NEXTITE 550, we recommend either the 1.2mm or 1.6mm tips or nozzles.

Instructions for use

1.     Ensure all bonding surfaces are clean and free of grease. Use NEXTITE PROPREP or ACRI-BOND CLEANER (for delicate materials) and allow the surfaces to dry completely.

2.     For low surface energy plastics, apply NEXTITE SP 901 Primer to the bonding area. Use sparingly and avoid excess application. Let the primer dry fully. Do not use primer on plastics that are not low surface energy.

3.     If required, NEXTITE CA-1 Activator can be applied. Apply to one bonding surface only. If a primer has been used, do not apply activator to the same area. Allow the activator to dry before proceeding.

4.     Dispense adhesive onto one surface only (never on the surface treated with activator). Assemble the components quickly, as the rapid fixture time provides little chance for repositioning.

5.     To cure excess adhesive or fillets outside the bond line, apply NEXTITE CA-1 Activator by spraying or dropping directly onto the exposed adhesive.

6.     Keep the parts fixed or clamped in position until the adhesive has achieved fixture.

7.     Allow the bond to reach full strength before applying service loads, which typically occurs after 24 to 72 hours depending on the bond line, substrates and environmental conditions.
