Micares X1087 BK Resin R11(P961) Elantas 2-component Self-extinguishing Polyurethane Sealant.

Application 

Micares®X1087 BK R11 is a flexible casting  resin system based on polyurethane, consisting  of resin and hardener. This two component  potting compound designed for use in the  electrical engineering and the electronics is cold  to thermal-curing. It is solvent free and liquid at  ambient temperature (RT). The resin component  contains the filler and is degassed. 

Processing 

 It is easy to process at ambient temperature and  atmospheric pressure. 

Description 

Flexible, synthetic materials. The resin adheres  well to metallic and non-metallic materials and  resists tracking. Dielectric loss are low. The  system is RoHS conform (European Directive  2002/95/EC) and the new RoHS Directive  2011/65/EU (RoHS 2) entered into force on 21 July 2011 and requires Member States to  transpose the provisions into their respective  national laws by 2 January 2013.The system is  UL 94V-0 listed.  

Instructions 

The resin and hardener are mixed according to  the specified ratio at ambient temperature,  preferably using automatic dosing and mixing  equipment. If the resin has been stored for a  long period of time, it is recommended to stir  well the complete content of the container and to  check the viscosity before the processing is  being started. Formation of lumps has to be  prevented by applying of appropriate stirring  conditions. The mixture is applied at ambient  temperature (above 18°C).The moulds should  be treated with a release agent (e.g. MICAFIL  8055) to facilitate subsequent mould removal.  For complicated components, or if optimal  electrical properties are specified, casting under  vacuum is required. Components and moulds  generally do not need pre-heating for casting  with Micares®X1087BK R11.Reactivity of the  casting compound however, can be changed on  request, and or by pre-heating the mould to  about 40℃ to 80℃, e.g., to reduce cycle-time.  Accelerator can be used without adverse effects  on the final properties of the resin. We can  supply a suitable product separately

Curing/post-curing 

This resin is especially designed for hardening at ambient temperature.The curing time depends  on the resin quantity and temperature. Final  curing therefore can be achieved after a few  hours or days. Or considerably less at higher  temperatures. The self-heating effect of low  exothermal reaction in the resin, depending on  the resin quantity, is usually sufficient to bring it  to final hardness in 10-24 hours.  

Storage 

Polyols and isocyanate based hardeners can be  stored for one year in the original sealed tins  stored in a cool, dry place. The hardeners may  present an increase in viscosity that does not  change the cured system properties. Both  components should be stored in appropriate  room in their originally sealed containers. Avoid  storage outside! The resin is chemically stable.  However, before use, the resin must be  carefully stirred with a suitable equipment since  all resins containing mineral filler tend to build  deposits. Stirring with particular care is  necessary, when the resin has been stored for a  long period of time. Important: the hardener  must be kept away from any exposure to  humidity. It should always be stored well sealed.
