CLEARLINK® / UNILINK®

Chain Extenders and Catalysts for Polyurethane & Polyurea


PRODUCT

DESCRIPTION

APPLICATION NOTES

Clearlink® 1000

Aliphatic diamine chain extender for use with aliphatic isocyanates in polyurethane and polyurea

– Produces tough, UV light-stable polyurethane and polyurea coatings with improved strength and heat resistance

– Can be applied using conventional spray techniques

Clearlink® 1080

Aliphatic diamine chain extender for use with aliphatic isocyanates in polyurethane and polyurea

– Produces durable, UV light-stable polyurethane and polyurea coatings with improved strength and heat resistance

– Low moisture sensitivity, slower reactivity and compatibility with a wide range of polyols, co-curatives and other polyurethane chemicals

– Can be applied using conventional spray techniques

Unilink® 1000 series

Zirconium-based polyurethane catalysts for filled and unfilled cast elastomers

– Delivers a fast cure profile,similar to tin, to maximize mold productivity in cast elastomers

– Suitable for use with aliphatic and aromatic isocyanates and all polyols

– Unilink 1030 is suitable for color-critical formulations

Unilink® 2000 series

Titanium-based polyurethane catalysts for filled and unfilled elastomers

– Slower, delayed cure profile, similar to mercury, wide formulating window and tailored polyurethane properties

– Suitable for use with a wide variety of isocyanates and primary polyols

– Moisture-tolerant and excellent storage stability in polyols

Unilink® 4200

Aromatic diamine chain extender for flexible polyurethane foams

– Improved compressive strength, tensile, tear, dimensional stability and load-bearing properties in standard TDI slab-stock foam and high-resilience foam systems

– Reduces foam density and softens cold-molded foam

– Improves mold flow and reduces mold time

Aromatic diamine chain extender for elastomeric coatings

– Cures TDI and MDI coating compounds at ambient temperatures.

– Can be applied by spray or pour-and-spread techniques

– Low viscosity improves handling, surface wetting, adhesion and finish
