Question 1

Which rubber substrates is RMB-150 compatible with?

Accepted Answer

RMB-150 is formulated for EPDM, neoprene (CR), and silicone rubber compounds. It is not recommended for natural rubber (NR) or butyl (IIR) systems without prior compatibility testing, as the organofunctional silane chemistry is optimised for polar and semi-polar elastomers.

Question 2

What surface preparation is required on the metal side before applying RMB-150?

Accepted Answer

Grit-blast metal substrates to Sa 2.5 per ISO 8501-1, then degrease with a ketone or ester solvent and apply RMB-150 within 4 hours. Spray or brush-apply at 5–10 m²/L and allow a minimum 10-minute open-time at 23°C/50% RH before bringing the rubber compound into contact under heat and pressure.

Question 3

Can RMB-150 replace a two-coat brass-plate plus secondary adhesive system?

Accepted Answer

Yes. RMB-150 is a single-coat system that eliminates separate brass-plating or two-part adhesive layers used in conventional rubber-to-metal bonding processes, reducing production steps and overall VOC load while maintaining equivalent peel and shear bond strength in standard 90° peel tests.
