Rubber or Acrylic Adhesive

Generic Rules:

Rubber Based  Adhesives

• Typically have good initial tack, and reach their full strength relatively quickly. This is important when you need to have the full use of your VELCRO® Brand Fasteners as quickly as possible.
• Indoor only as they are susceptible to strong temperatures, UV and moisture.

Acrylic  Adhesives

• Typically take a longer time to set (72 hours), but typically have a greater bond with the substrate.
• More resistant to moisture and can withstand a greater range of temperatures than rubber adhesives.
• Acrylic adhesives also tend to not break down over time
