    Given the estimates of archaeologists, we have now used adhesives for more than 20 million years. Our progress is very significant, especially after the PUR adhesive is used. Epoxy resins, polyurethanes, cyanoacrylates and acrylic polymers, when we want to combine two things together, by providing high performance and high efficiency, make our lives richer. Adhesives are everywhere in the building world, from packaging to products, to infrastructure. However, these wonderful synthetic materials have been costly and many are deadly toxins.

    In the past, most of our synthetic adhesives come from nature: from the animal part of the protein or product, such as milk and eggs, starch or natural resin from the plant. Researchers are now looking for new ways to provide new sources for better work and non-toxic glue. Their goal is to imitate the natural chemistry, not the use of natural resources.

    Vegetables or animal glue is still widely used because they are relatively inexpensive and environmentally friendly. However, the glue made from natural materials tends to have lower moisture resistance, heat resistance and chemical resistance than synthetic adhesives. In addition, the synthetic binder may be formulated in its intended application for the particular properties required for ease of administration and durability.

    Rubber adhesives are PUR adhesives that are elastomers and are a large range of adhesives for many applications. Natural rubber has limited properties as binders, but when processed and combined with additives, its properties are adjusted to provide excellent adhesion to specific substrates, better temperature resistance and higher cohesion strength.

    The manufacture of a rubber-based adhesive is generally a method of dissolving a natural rubber with a solvent, adding a resin and other compounds and using a chemical catalyst or heat to form a specific polymer. The most common polymer-based adhesives made from rubber include polyalkylene, styrene, polyisobutylene, polysulfide, polyamide, silicone and polyurethane.
