Leather Additives

ADDSiL™ 2005 is a hydroxyalkyl-terminated silicone compound with highly reactive CH₂OH terminal groups, offering greater reactivity than Si-OH. It integrates silicone into polyurethane materials, enhancing flexibility, water resistance, smoothness, and weather resistance through reaction with isocyanate. It is similar to DOWSIL-3667 and DOWSIL-8427.

ADDSiL™ 2005

Introduction


ADDSiL™ 2005 is hydroxyalkyl-terminated silicone compound that has high reactive terminated functional group CH2OH. That reactivity is higher than the Si-OH as the reaction functional group.


ADDSiL™ 2005 can bring silicone into the polyurethane materials to improve the flexibility, water resistance, smooth, weather resistance and so on the characters, through reacting with isocyanate.

Applications


  • Carbinol-functional polydimethylsiloxane ADDSiL™ 2005 can reduce surface tension, improve the wettability of release paper and substrates, and improve the leveling and anti-crater and pinhole properties of the resin.


  • ADDSiL™ 2005 can react to form polyurethanes, epoxies, polyesters, and phenolic resins.


  • ADDSiL™ 2005 can be used as additives in polyurethane leather finishes and reactive internal lubricants in melt spinning of polyester fibers. It can increase softness and provide smooth surface and smooth feel to PU synthetic leather.


  • ADDSiL™ 2005 are also used as surfactants and processing aids to disperse particles in silicone formulations.


Recommended Dosage


The amount of addition depends on different requirements, 0.2-1% for hand feel improvement, 2-6% for anti-stick stains, and 1-6% for resin modification. It can be added at any stage of production and is suitable for water-based and oil-based systems.


Packing


ADDSiL™ 2005 is supplied in net weight 25Kg metal pail.
