Rubber adhesion Amino crosslinkers Ra72 HRH dry rubber adhesion systems
Haminol Ra72 resins are a portfolio of HMMM-based resins using precipitated silica as a carrier. These resins are 72% active ingredient HMMM and function as adhesion promoter or crosslinker in the "HRH" dry rubber adhesion systems for bonding rubber to organic cord and wire reinforcement materials. This product offers several advantages over the older hexa methylene tetramine (HEXA or HMT) system. It belongs to the methylene donor adhesive. It is used with methylene acceptors to bond rubber to skeleton materials such as steel wire.
Haminol Ra72 are used in applications as a methylene donor in the"HRH" dry rubber adhesion systems for bonding rubber to organic cordand wire reinforcement materials. To improve adhesion as well asphysical properties Haminol Ra72 should be used together with silica in the compound.
