Velcro® USA uses a "B" indicator on the release liner for Rubber based adhesives. An "R" indicator is used for the Acrylic based adhesives. Both types of adhesive are pressure sensitive, which means that they are applied to an object by pressing it on. Deciding between a rubber or acrylic-based adhesive hook and loop product depends upon the type of material it is being attached to, the environment it will be used in and the situation in which it will be used.Rubber Adhesives
Rubberised tape is a synthetic polymer that is often used in the hook and loop fastening system. It is usually less expensive and has a higher initial tack quality than acrylic-based adhesives, but rubber adhesive is more susceptible to moisture and high temperatures, which may cause it to break down over time. It is also not a good choice for use with solvents or chemicals that can wear away at the rubber. Rubber provides great adhesion on rough or uneven surfaces, especially wood, glass, stainless steel, aluminum, drywall, and plastic items. It's best used in indoor situations where there is less of a chance of drastic temperature changes. It provides an excellent amount of light-duty staying power.

Acrylic Adhesives
Acrylic-based adhesive is a synthetic fiber made from a polymer. In addition to hook and loop fasteners, a wide variety of products are made from acrylic, including textiles and home furnishings. They work well on a smooth, flat substrates such as metal, glass and some plastics. The acrylic adhesive is great for outdoor and waterproof items. Acrylic adhesive holds up well to moisture and can sustain drastic temperature changes as well as seasonal elements such as ultraviolet light and freezing conditions. It takes about 24 hours for an acrylic-based adhesive to completely bond to a surface. An excellent choice for rugged outdoor conditions and varying temperatures, acrylic is resistant to solvents and chemicals, making it a useful product for the industrial sector. Acrylic adhesive is more expensive than rubber adhesive but has the staying power to provide years of use. Shop for acrylic adhesive-backed hook and loop tape here.Additional FAQs:
Q. What is an acrylic adhesive used for?
A. Acrylic adhesives are versatile and suitable for bonding smooth, flat substrates such as metal, glass, and certain plastics. They are ideal for outdoor and waterproof items, holding up well to moisture and sustaining drastic temperature changes as well as seasonal elements such as ultraviolet light and freezing conditions.
Q. Is acrylic adhesive waterproof?
A. Yes, most acrylic adhesives are waterproof and resistant to moisture, making them suitable for both indoor and outdoor applications.
Q. Is acrylic adhesive suitable for outdoor applications?
A. Yes, acrylic adhesives are suitable for outdoor applications. They can sustain drastic temperature changes and withstand seasonal elements such as ultraviolet light and freezing conditions, making them ideal for use in varying outdoor environments.
Q. What materials can rubber-based adhesives bond effectively?
A. Rubber-based adhesives provide great adhesion on rough or uneven surfaces, especially wood, glass, stainless steel, aluminum, drywall, and plastic items. They are best used in indoor situations where there is less chance of drastic temperature changes.
Q. What is the best acrylic adhesive?
A. Deciding between a rubber or acrylic-based adhesive depends on the material, environment, and application. Acrylic adhesives are best for outdoor use, offering durability, UV resistance, and strong bonding on smooth surfaces like metal and glass. They withstand temperature changes, making them ideal for long-term applications in varying conditions.
Q. What is stronger rubber or acrylic adhesive?
A. Acrylic adhesive is generally stronger than rubber adhesive. Acrylic adhesives offer better durability, resistance to environmental factors like UV light and temperature, and provide a longer-lasting bond. Rubber adhesives, while more flexible, are better suited for temporary or low-strength applications.
Q. What is the strongest type of adhesive?
A. The strongest type of adhesive is typically considered to be epoxy. It forms extremely durable, high-strength bonds that are resistant to heat, chemicals, and impact, making it ideal for heavy-duty applications on a wide range of materials.
Q. What Is the Best Glue for Rubber Adhesion?
A. The best glue for rubber adhesion is cyanoacrylate (super glue) because it bonds quickly and forms a strong, durable bond. For more flexible or high-stress applications, a rubber adhesive like contact cement or silicone-based glue is better, as it provides flexibility and resistance to water and temperature changes.
