General Description
UVALAM Hybrid HA20 is two-component 2:1 hybrid flexible adhesives with a unique combination of high elongation, high peel and shear strength.
UVALAM Hybrid HA20 provides a flexible bonding with feature of a wide range of dissimilar materials, including metals, engineering composites, thermoplastics (PMMA, ABS, PA66 and PC), glass, etc.
UVALAM Hybrid HA20 is supplied in 400ml side-by-side 2:1 cartridge.
Features:
• Withstand severe thermal shock.
• Good ageing resistance and low moisture absorption.
• Does not contain solvent.
• Be particularly suitable for bonding materials with different CTE.

TYPICAL CURING PROCESS
The cure of this adhesive can be affected and accelerated by elevated temperatures,
typical curing process recommend as curing for 24 hours @25ºC followed by 4 hours @60ºC.
STRENGTH AFTER AGING
The lap shear strength of bonded aluminum and aluminum will retain ≥7 MPa after cured for 168 hours at 25ºC and then aged by thermal shock from -40~80 ºC.
STORAGE & SHELF LIFE
The product is sensitive to moisture in the air.
Store the unopened product in a cool, dry, well ventilated location, away from sources of moisture and heat.
Optimal storage temperatures should range between 10 ºC and 30 ºC.
Product removed from the containers during use should not be returned to original containers in order to avoid potential contamination.
The shelf life of Part-A and Part-B is 6-9 months.
