CTBN| Carboxyl-terminated Polybutadiene Acrylonitrile Liquid Rubber

Introduction and application of CTBN| Carboxyl-terminated polybutadiene acrylonitrile liquid rubber

1. Brief description:
CTBN modified epoxy resin with about 25% acrylonitrile can be made into a metal structural adhesive with high strength, toughness and fatigue resistance, which can be used for bonding structural parts of aircraft; used for bonding organic glass and polyester tape, and its performance is significantly improved; the adhesive can also be used for the infiltration of various fabrics (glass fiber, polyester, carbon fiber). The
room temperature curing adhesive prepared by CTBN and epoxy resin is used to bond aluminum materials, and the highest bonding strength is reached after 72 hours. The peel strength is 0.55Mpa, and the shear strength at 90℃ is 26.7Mpa; CTBN modified epoxy resin is used to prepare electrical component packaging materials, and there is no crack phenomenon after 200 cycles between -55.0 and 150℃, which improves the anti-cracking ability; CTBN can also be used as an adhesive for abrasives to manufacture grinding wheels and cutting wheels. It has the characteristics of less adhesive and wear resistance, good polishing effect, and resistance to hot water and cutting coolants. The
viscosity of CTBN increases significantly with the increase of the nitrile content in the molecular chain. The amount of additives (colorants, stabilizers, curing agents, fillers, etc.) used during use depends on the viscosity. Viscosity is an important indicator of performance. The acrylonitrile content has a great influence on the processing performance and use of CTBN, and the introduction of acrylonitrile in the molecular chain increases its compatibility with phenolic resin and epoxy resin, and improves the bonding performance, oil resistance and crack resistance. CTBN products have good aging resistance, corrosion resistance, excellent thermal stability, low temperature resistance and strong mechanical properties.
