DR-ADTX / DH-AD: Thixotropic Adhesive Paste

 


 

 

 

General Description:

DR-ADTX is a thixotropic adhesive with fillers and fibers to allow excellent bondline control when bonding composite and metal structures. 

This two phase resin along with its internal coupling agents allows excellent adhesion to both fiberglass and metal parts.

 

Applications:

Applications include: Honeycomb panel fabrication where low sag and good fillet formation is needed.  Bonding of metallic and fiberglass

reinforced composites.

 

Processing:

Mix resin and hardener thoroughly at specified ratio.  Resin can be heated slightly to lower viscosity.  Do not expose resin or hardener to excessive moisture conditions until fully cured.  Post-cure adhesive to 140oF to achieve maximum cure and composite strength.  In cases of free standing post-cures, the part should be heated slowly (20-30oF per 30 minute steps) to prevent warpage.
