Polyurea Spray Coatings

• Two component solventless coatings (zero VOC) – A Side: Isocyanate prepolymer

– B Side: Resin blend containing • Amine Curative hard segment

• Polyetheramine soft segment

• Systems are fast reacting – Quick return to service

– Need to moderate reactivity for cure rate control and smooth surface

• Most systems are aromatic (MDI and Ethacure 100) and thus lack UV/color stability.

PDA Europe 2011 Annual Conference –The Hague, 14-16 November 6

Ethacure® 90

• New aliphatic amine curative commercialized in 2011 (TSCA registration in US in February).

• Chemical structure designed to provide moderate cure speed.

• Allows formulation of robust fully aliphatic spray polyurea systems.

• Global registration underway.

Aliphatic Polyurea Coatings

• The aliphatic polyurea coating system in this presentation is based on an HDI polyisocyanurate.

• Screening of formulations involved: – Mixing resin side components in a Speedmixer

– Providing a 1:1 volume ratio with a dual cartridge syringe

– Mixing iso and resin through a static mixer equipped with an air spray nozzle.

• Gel times were obtained by measuring time until the material no longer flowed when sprayed on a vertical surface

PDA Europe 2011 Annual Conference –The Hague, 14-16 November 8

Ethacure 90 gives significantly longer gel times

with HDI than other aliphatic secondary amines.

Decorative Coatings

• Aliphatic system allows the colorful coating on this

Conclusions

• The commercialization of Ethacure 90 in 2011 provides a new slow aliphatic diamine for formulators, allowing the formulation of robust fully aliphatic spray polyurea systems.

• The cure rate is slow enough to allow one to formulate with faster primary amines like PEA D-400 and IPDA.

• The WVTR of the aliphatic polyurea is less than half of that of the aromatic polyurea systems.

• The improved moisture barrier performance allows application of a thinner aliphatic polyurea coating, significantly improving the system economics.

• Global rollout and registrations in 2011-2012.
