Rapidstick™ 8-411 Structural Adhesive

Rapidstick™ 8-411 Structural Adhesive is a two-component, 100% reactive toughened adhesive with excellent impact, peel, and shear resistance in a convenient 10:1 mix ratio. Its non-sagging and thixotropic formulation is specially formulated to bond acrylics, polycarbonates, various plastics, and metals to themselves and each other.

8-411 fills gaps up to 0.2mm and is room temperature cured with a short open time, forming a strong and durable transparent bond that is resistant to humidity and moisture, chemicals, and temperature fluctuations. It is ideal for applications requiring optical clarity with excellent adhesion to diverse substrates. Boasting excellent UV resistance, 8-411 is typically used for channel letter assembly, outdoor signs, and structural bonding of plastics and metals.
