VELCRO Brand Adhesives Guide

VELCRO® Adhesives Guide for Hook & Loop Fasteners

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® 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

    BE CAREFUL. Make sure to follow all manufacturers safety precautions. As always, for best results make sure surfaces are thoroughly cleaned before applying any adhesive. Citrus cleaners are not recommended for any VELCRO® adhesives. Ideally adhesives are applied at room temperatures with low humidity. VELCRO® adhesives are not recommended for submersion in water or on substrates with high levels of plasticizers. They cannot be washed or dry cleaned
