Question 1

What substrates can RPS-200 bond effectively?

Accepted Answer

RPS-200 is formulated for metal-to-metal (steel, aluminium) and rubber-to-metal bonds, including brake lining-to-backplate assemblies and vibration-damping composites. Surface preparation via sandblasting or phosphating plus a primer coat is recommended for optimal adhesion.

Question 2

What are the recommended hot-press cure conditions for RPS-200?

Accepted Answer

Cure at 170–180°C under 1–3 MPa contact pressure for 20–30 minutes, followed by ambient post-cure for 24 hours before mechanical testing. Inadequate press pressure during cure leads to voids and significantly reduced lap shear values.

Question 3

Is RPS-200 suitable for aerospace and high-temperature structural applications?

Accepted Answer

Yes. The nitrile rubber phase provides peel resistance and flexibility while the phenolic resin network delivers continuous-use thermal resistance up to 180°C and long-term fatigue durability, meeting requirements for non-primary aerospace bonding and friction material (brake lining) production.

Solids Content	42–48%
Cure Conditions	175°C / 30 min, 1–3 MPa press
Density (25°C)	0.95 g/ml
Viscosity (25°C)	8,000–15,000 mPa·s
Lap Shear Strength (Steel)	>10 MPa
