RBR – 100  Introduction
RBR 100 is a functionalised polymer resin obtained by reaction with formalin in Acidic media. This is based on Cashew Nut Shell Liquid with high bonding used for manufacture of friction elements such as brake linings and clutch-facings along with asbestos, fillers and friction dust. Compatibility RBR 100 is compatible with phenolic, epoxy and alkyd resins. SolubilityRBR 100 is soluble in White Spirit (MTO), Xylene, Ester, Ketonic solvents, etc. PropertiesColour | Dark Reddish brown | Specific Gravity | 0.95 – 0.98 | Solid content | 100 +/- 1% | Viscosity @ 30°C | | Brookfield Viscometer | 20000 - 30000 cps | PH | 2 – 4 | Gel Time @ 150°C | | with 5% Hexa | 30 minutes (Max.) | Shelf Life | 12 months if kept in airtight containers | Storage | Should be kept in dry conditions |
