3M Scotch-Weld DP100 Plus Clear – 4 Minute Flexible Fast Set Epoxy

Description

3M Scotch-Weld Epoxy Adhesive DP100 Plus Clear is a fast setting, two-part, 1:1 mix ratio mercaptan-cured epoxy adhesive. It is unique among fast setting mercaptan cure epoxies in that it combines high shear strength with good peel performance properties. Scotch-Weld epoxy adhesive DP100 Plus Clear is transparent and slightly flexible when cured.

Features:

• 4 Minute Work Life
• High Shear & Peel Strength
• Slightly Flexible When Cured

Overlap shear (OLS) strengths were measured on1 in. wide 1/2 in. overlap specimens. These bonds were made individually using 1 in. x 4 in. pieces of substrate. The thickness of the bond line was 0.005-0.008 in. All strengths were measured at 70F (21C) except where noted. (Test per ASTM D 1002-72.)

The separation rate of the testing jaws was 0.1in. per minute for metals, 2 in. per minute for plastics and 20 in. per minute for rubbers. The thickness of the substrates were: steel, 0.060 in.; other metals, 0.05-0.064 in.; rubber, 0.125 in.; plastics, 0.125 in.

13 T-peel strengths were measured on1 in. wide bonds at 73F (23C). The testing jaw separation rate was 20 inches per minute.

The substrates were 0.020in.thick.(TestsperASTMD 1876-61T.)

14 Solvent resistance was determined using cured (24hrs. RT + 2 hrs. 160F [71C]) samples (1/2 in. x 4 in. x 1/8 in. thickness) immersed in the test solvent for 1 hour and 1 month. After the allotted period of time, the sample was removed and visually examined for surface attack as compared to the control.

Key: A – Unaffected – no change to color or surface texture.

B – Slight attack – noticeable swelling of surface.

C – Moderate/severe attack – extreme swelling of surface.
