Acrylics are multifaceted polymers that can be used in a wide variety of situations including construction, textile and pressure sensitive applications. Bond strengths produced range from very high for multi-component curing systems to low strength peelable pressure sensitive products. Adhesives and sealants formulated on acrylic polymers exhibit high UV resistance and they can be formulated in emulsion or organic solution forms.
A specific category of curing acrylic chemistry, that cure in the absence of oxygen. Most commonly used for ‘threadlocking’ engineering and electronic applications.
Animal glue has been used as an aqueous adhesive for thousands of years, and is derived from collagen extracted from animal and fish skins as well as tendons and the proteinaceous matrix of bones. Gelatins are extracted from essentially the same feedstocks but by different treatments. The dry glues are hard and water soluble, but solvent resistant, and the major applications include coated abrasives (sandpapers) and remoistenable adhesives.
