First, characteristics Second, cultivation techniques Toughening agent refers to the material that can increase the flexibility of adhesive film. Some thermosetting resin adhesives, such as epoxy resin, phenolic resin and unsaturated polyester resin adhesives, have low elongation and high brittleness after curing. When the adhesive parts bear external forces, they are easy to crack and rapidly expand, resulting in cracking of the adhesive layer, fatigue resistance, and can not be used for structural bonding. Therefore, we must try to reduce brittleness, increase toughness, improve the bearing strength. Any material that can reduce brittleness and increase toughness without affecting other major properties of the adhesive is a toughening agent. It can be divided into rubber toughening agent and thermoplastic elastomer toughening agent.
