Elastomer Bonding Agent
Polymers and heat reactive components in an organic solvent system.
Chemosil 225 is a versatile, heat activated bonding agent which will bond a variety of rubber compounds to metal and plastic substrates.
In some circumstances Chemosil 225 may be used as a single coat. For general use it should be used in combination with an appropriate metal primer such as Chemosil 211. When used with Chemosil 211 the in service environmental resistance of the final bond will be very much improved.
Chemosil 225 bonds elastomer compounds based on natural rubber (NR), butadiene (BR), isoprene (IR), styrene butadiene (SBR), butyl (IIR), nitrile (NBR) and chloroprene (CR) rubber to most metals, alloys and polar polymeric substrates.
Bonding occurs during the vulcanisation of the rubber. Typical cure temperature ranges for moulding processes are 130-180°C. Lower temperatures of around 100°C with extended cure times of many hours may also be used for tank lining applications
Chemosil 225 by formulation does not contain lead-compounds and can therefore be used as direct replacement for Chemosil 220 and 222.
