Elan-tech® ADH 891.892 NF from Elantas is a temperature resistant high performance adhesive based on epoxy resin for bonding CFRP and GFRP materials, wood, glass, ceramics, rigid foams, as well as FE and non-ferrous metals in automotive construction and sports equipment.
This high performance adhesive is an unfilled and stable 2 component epoxy resin adhesive. The adhesive complies with RoHS (EU Directive 2002/95/EC) and RoHS Directive 2011/65/EU (RoHS 2).
Due to its thixotropic formulation thick, uneven and even vertical adhesive joints can be achieved.
High lap shear strength (up to 39 MPa with CFK cured 2 h over 80 °C according to ASTM D 1002)
Very high impact and peel strength
Good thermal resistance
Thixotropic formulation
Low exothermic reaction and shrinkage
Solvent free
Processing:
Processing is very easy due to the application with a dosing gun. This also eliminates mixing errors. Elan-tech® ADH 891.892 NF cures at room temperature or elevated temperatures. Post-curing at elevated temperatures is required to achieve maximum temperature resistance.

*2 mm application at 25 °C with good wetting of the surfaces to be bonded. The processing time is reduced accordingly for thicker coatings and the resulting exothermic (reaction heat).
** Curing time until a minimum tensile shear strength of 1 MPa is reached on aluminium.
