Cyanoacrylate adhesives, commonly known as instant adhesives are one-part, room-temperature curing adhesives available in a wide range of viscosities, which are known for fast and reliable bonds with instant high performance bonding of numerous materials, such as rubber, metals, wood, plastic and polystyrene. 90% of Instant Adhesives currently used for general purposes is ethyl cyanoacrylate and the rest is methyl cyanoacrylate. They are used due to instant bonding effect, even when used in low volumes. Instant adhesives would penetrate new markets if qualities, such as low bleaching and low odor are modified.
Inferior heat and impact resistance, inferior pliability, inability to adhere a large area in one stroke, odor and whitening, toxicity that may lead to skin disease are some of the major disadvantages of instant adhesives. Instant adhesives are extensively used in chemical machinery and equipment, automotive industry, musical instruments, precision equipment and domestic operations.
Cyanoacrylate is mainly used as it has one-solution, one-catalyst property along with excellent electric insulation and chemical resistance. Weak resistance to moisture and heat along with low shearing strength are weakness of instant adhesives. They are used as temporary adhesive in electronics, woodworking, medical, cosmetics, and forensics applications. Epoxy-based instant adhesives are mainly of two types, namely cold cure adhesive and heat cure adhesive. Cold cure adhesives provides high strength bonding with fast curing at room temperature, wide range of viscosities with gap-fill versions, long term durability and uniform stress distribution, low odor and VOC content, resistance to cracking and abrasion with excellent adhesion to similar or dissimilar substrates. Hot cure adhesives are used above 100°C. They provide several advantages over solvent-based adhesives, which includes high shelf life with easy disposal without any special precautions. Drying and curing step can be eliminated in hot cure adhesives. These adhesives provide greater and harder bond strength along with toughness, rigidity and high impact resistance. They have applications in automotive, aerospace, electronics, bookbinding, packaging, medical, and oil and gas industry.
Instant Adhesives Market Outlook
