Applications SDPspray HP 93
The SDPspray HP 93 system is a two-component Polyurea coating, applied by high-pressure hot spraying. The reaction is almost instantaneous, forming a highly resistant, seamless continuous membrane with a Shore 93A hardness.
The SDPspray HP 93 Polyurea system is a coating specifically developed to waterproof flat roofs.
It is highly valued for
- Its excellent mechanical properties
- Its excellent elasticity and low aging
- Its excellent smoothing power
- Its insensitivity to water (Nco-nh2 reaction faster than Nco-h20)
- Its excellent economic efficiency
The SDPspray HP 93 Polyurea system is a two-component product intended for application via a mobile in-situ injection machine. The product temperature is > 60°C and the product pressure is > 130 bar.
The Polyol is a composition based on amino Polyether polyols and 100% reactive amines.
The Isocyanate is an MDI prepolymer.
