Products in Diols & Polyols: High Hardness

POLYSORB® PS A is a solid pastille product with a monomer and intermediate function. It is known for its high purity, and its base chemical properties encompass heat resistance and high hardness. This product is primarily targeted at industrial markets and finds applications in chemical and industrial manufacturing, as well as resin manufacturing. The end uses for its base chemicals include plasticizers, polyols, and solvents.

STEPAN® MWA-560 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that can exhibit hydrolysis resistance and good thermal stability. It can also exhibit a good hardness/flexibility balance, clarity, and low color. It can be used in metalworking formulations for improved lubrication properties. It shows improved lubrication by showing a reduced average scar when compared to the current industry standard.

STEPAN® MWA-570 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that exhibits hydrolysis resistance and good thermal stability. It exhibits a good hardness/flexibility balance, clarity, and low color. It is used in metalworking formulations for improved lubrication properties and is a great option as a chlorinated paraffin replacement, either alone or with the addition of phosphate esters. It also shows improved lubrication by showing a reduced average scar when compared to the current industry standard.

It is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters, polycarbonates and polycaprolactones Plasticizers

HDO® 1,6-Hexanediol Flakes is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters and polycarbonates Plasticizers

HDO® 1,6-Hexanediol Molten Low PCF is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters and polycarbonates Plasticizers

Neol® Neopentyl Glycol Sol. 90% is a colorless aqueous slurry with a mildly sweet odor. It is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters, polycarbonates and polycaprolactones Plasticizers

K-FLEX® UD-320 is a high solids, aliphatic, low molecular weight urethane diol oligomer. It is soluble in polar organic solvents and has broad compatibility with acrylic, polyester, and alkyd resins. K-FLEX® UD-320 will increase the hardness of a melamine crosslinked system. When used to modify a 2-component polyurethane, it will increase hardness and flexibility. K-FLEX® UD-320 responds best to a zirconium chelate catalyst when used in isocyanate crosslinked systems.

K-FLEX® UD-320-100 a 100% solids version of K-FLEX® UD-320 recommended for prepolymer synthesis and 100% solids WB/SB melamine crosslinked systems or 2K PU. Used for preparation of polyester polyurethanes or alkyd polyurethanes. It provides hardness and exterior durability.

K-FLEX® UD-350W is an aqueous solution of an aliphatic, low molecular weight urethane diol oligomer. It is recommended as a modifier for amino crosslinked water soluble and emulsified acrylic, alkyd, urethane and polyester resins. K-FLEX® UD-350W can be used as a reactive cosolvent replacement to increase solids, crosslink density, improve film/resistance properties and flow/leveling.

K-FLEX® XM-337 is an aliphatic saturated polyester diol modifier resin designed to provide increased toughness and chemical resistance for solvent-based and high solids systems. It is recommended for use in 1 and 2 component polyurethanes, and blocked isocyanate systems. Benefits include low color, UV durability, high hardness, high impact resistance, abrasion resistance and overall increased toughness.
