Tec-Bond® 240 & 261 Water Based Fastener Adhesives and Threadlockers

Tectorius Tec-Bond® water-based thread adhesives are unique products that directly replace traditional solvent-based chemistry. They have been designed specifically to transition long proven reliable epoxy performance into state of the art, environmentally friendly chemistry. The combination of a solvent free, REACH and RoHS compliant composition with tight physical performance character make them the perfect match for progressive, global manufacturing.

Tec-Bond 240 is the water-based alternative to Tec-Bond 235.

Tec-Bond 261 is the water-based alternative to Tec-Bond 251.

Tec Bond 240 Water Based Fastener Adhesive and Threadlocker

DESCRIPTION:

 Tectorius Tec-Bond® 240 and 261 are unique water-based thread adhesives that directly replace traditional solvent-based chemistry. These products have been designed specifically to transition long-proven reliable epoxy performance into state of the art, environmentally friendly chemistry.  The combination of a solvent free, REACH and RoHS compliant composition with tight physical performance character makes it the perfect match for progressive, global manufacturing. 

The properties built into Tec-Bond 240 and 261 address many shortcomings of past generation competitors, including resistance to humidity and extended storage. 

Tec-Bond thread adhesives are microencapsulated, room-temperature curing adhesives that bond threaded fasteners in place.     Pre-applied fastener adhesives are designed to be coated on the fasteners in bulk at Tectorius service centers ready for future assembly. In any application, Tec-Bond will remain dormant until the shearing action of installing the fastener breaks the specialized microcapsules and triggers the adhesive to react. 

 

Tec-Bond 240 and 261 are available in two grades:

· Industrial Strength: (Tec-Bond 240-IN and 261-IN) are suited for general-purpose use.

· Precision Strength: (Tec-Bond 240-PR and 261-PR) were developed with precision assemblies in mind where performance on titanium, stainless steel, special alloys, or plastics is needed.
