PRODUCT DESCRIPTION

DEDT H-1050 is a toughened , medium high viscosity , rapid curing industrial grade epoxy

structural adhesive with excellent strength. Once mixed , the two-component epoxy cures at

room temperature which provides high peel resistance and high shear strength to a wide variety

of materials including plastics , metals , glass and ceramics. It’s high transparency , high

permeability , and rapid curing at lower temperature characteristics , makes it suitable for many

bonding applications.

DIRECTION FOR USE

1. For best performance surfaces should be clean and free of grease. Removal of surface

contaminates such as paints , oxide films , oils , dust , mold release agents before bonding.

2. Use gloves to minimize skin contact and keep the work environment in an good air flowing

status.

3. Mix thoroughly by weight in the proportions. Mix vigorously approximately 1~3 minutes after

uniform color is obtained. Keep parts from moving during cure. Contact pressure is

necessary.

4. Excess uncured adhesive can be cleaned up with ketone type solvents.

STORAGE

Optimal storage is in a cool , dry location at a temperature between 8°C to 28°C. Shelf life can

be 1 year under 25℃ storage.
