NEXTITE 501 Surface Insensitive, Porous Materials

NEXTITE 501 is a high performance surface insensitive instant adhesive meaning it delivers high strength, reliable bonds across a wide range of materials making it an ideal general purpose solution. With its medium viscosity and fast cure speed, it sets in seconds on most substrates, providing virtually instant bonding on a wide range of materials including plastics, metals and rubbers. The surface insensitive formulation ensures consistent results even on rough, porous and acidic surfaces. While its high temperature resistance of up to 120°C makes it suitable for demanding applications.

Product Overview

NEXTITE 501 is a surface insensitive instant adhesive which provides dependable bonding even on difficult substrates. It’s all around general purpose formulation makes it ideal for a wide range of applications including bonding plastics, metals and rubbers. Its surface insensitive formulation allows for bonding on rough, porous and acidic surfaces where other instant adhesives fall short. In addition to this, NEXTITE 501 offers excellent heat resistance, maintaining strong adhesion at temperatures up to 120°C. Perfect for both high strength bonding applications and any fast at home jobs or repairs.

NEXTITE 501 has a medium viscosity 90 – 110 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 501 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 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.

 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. 

Applications and Uses

NEXTITE 501 has been designed as a surface insensitive instant adhesive. It is ideal for industries and tasks that require a general purpose adhesive with instant bond and high strength. It is also ideal for surfaces that have a rough, porous or acidic surface making this adhesive a true allrounder.

Tools and Accessories

The 20g and 50g 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 501, we recommend either the 0.6mm or 0.8mm tips or nozzles.

Technical Highlights

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.
