New Tolonate™ X FLO 100

Putting the care into chemicals

• Partially bio-based, aliphatic isocyanate polymer,

• Based on Hexamethylene Diisocyanate (HDI),

• Solvent free, extremely low viscosity, • Tolonate™ X FLO 100 is designed to produce solvent-free polyurethane materials and/or to reduce volatile organic compounds (VOC) emissions of polyurethane formulations.

• Its functionality being 2, Tolonate™ X FLO 100 can be used as a building blocks to produce UV-curing resins, TPU’s, PUD’s….. or any other urethane chemistry

Tolonate™ X FLO 100 :Bio-based & Low viscosity

Putting the care into chemicals

Much more thaninnovative chemical solutions

• Partially bio-based. it contains:

• 32% of “green carbon” : measured according to ASTM-D6866 standard (14C measurement). This is the weight % of carbon of the renewable part vs total amount of carbon of the molecule.

• 25% of renewable material according to the evaluation done by ACDV (Association Chimie Du Végétal). Weight of all atoms (not only C) of the renewable part vs total weight of moleculeThis can be advertised using the specific logo of the ACDV:

Putting the care into chemicals

• Tolonate™ X FLO 100 is registered in the USA. Canada. China. Taiwan. Korea. Japan and considered as a polymer in Europe (therefore exempted for REACH registration requirements).

• New products based on Tolonate ™ X FLO 100 will also benefit from the polymer status in Europe.

• Toxicological profile is similar to other HDI-oligomers:• H317: May cause an allergic skin reaction.• H335: May cause respiratory irritation.

Tolonate™ X FLO 100Safety/Regulatory position

Where we can use it ?What will be the effect ?

Tolonate™ X FLO 100 can be used as a crosslinker or co/crosslinker (reactive diluent). It is recommended to mix it with other polyisocyanates to increase the functionality and reach efficient crosslinking.

Tolonate™ X FLO 100 is also suitable as building block thanks to its NCO functionality around 2.

Functionality around 2 makes Tolonate™ X FLO 100 suitable as a reactant in the synthesis of coatings resins:

• Polyurethane acrylates (PUA). • Polyurethane dispersions (PUD)• Thermoplastic urethanes (TPU) . ...

Main benefits will be :

• Better toxicity profile compared to monomers,• Polymer status (in Europe),• “high” reactivity (same as HDI) vs IPDI or H12MDI,• Positive impact of the flexibility (PUD for leather) and

viscosity of the end resin.

Crosslinker for cast elastomers

• Ideal for polyurethane cast elastomers application where light stability and optical clarity are needed.

• Will help reaching low viscosity, ideal for potting applications

• Improves the compatibility with hydrophobic resin like Hydroxy Terminated Poly Butadiene (HTPB).

• Main usage: soft to semi hard materials (shore A = 25-80).

Crosslinker for cast elastomers

• Main benefit of Tolonate™ X FLO 100 : • “cutting power” (viscosity), • improvement of elongation performances (however unlikely

to be used a single hardener).

Soft formulation based on HTPB

•Moisture cure coatings (MC) are 1 K systems where the polyisocyanate which will react with water –moisture (no resin).

•A ~80/20 combination with Tolonate™ HDT-LV2 can provide low viscosity and right functionality to match the desired level of hardness.

• Systems do not contain solvent. Viscosity and compatibility are key for good end properties.

• Benefit of Tolonate™ X FLO 100:• Viscosity, • Flexibility (performances at break).

• Recommendation is to use Tolonate™ X FLO 100 in combination with standard HDI-trimers or biuret to maintain good chemical resistance.

Xlinker in solvent free systems:100 % 2K Polyurethanes

• Polyureas are being used to a growing extent in coatings and materials, as an alternative to PU. Main benefit is fast reactivity & hardness.

• Typical application : coatings for flooring, protective (windmills, tanks, containers, pipe coatings, ...) but car refinish applications are also raising.

• To be recommended in combination with others polyisocyanates to avoid damaging hardness and chemical resistance.
