High Airflow Isocyanate

Hot sale Toluene Dissocyanate/TDI

Toluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents. TDI (CAS No. 26471-62-5) consists of two isomers: toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI) (CAS No. 91- 08-7), which is commercially produced in different ratios. The most common ratio is 80% 2,4-TDI/20% 2,6 TDI. TDI is widely used and accounted for 34% of the global isocyanate market in 2000
Tdi 80/20 is used for Flexible Polyurethane Foam and other other polyurethane applications including elastomers,synthetic leather,coated fabrics,paints and adhesives.
It is spray-applied,closed-cell polyurethane foam system with high fire resistance properties.it applies to all kinds of spray-applied thermal insulation engineering,such as building exterior cold rooms,large-scale pipeline,etc.

JADEWIN LS 123 has been developed especially for high solids, acid catalyzed automotive and industrial coatings, i.e. two coat metallic thermosetting acrylate systems or one coat opaque thermosetting acrylate and polyester coatings.

JADEWIN LS 123 is recommended for applications such as: automotive and industrial coatings· decorative paints and wood stains or varnishes.

Its high efficiency has been demonstrated in a variety of other binders and applications such as:

middot;alkyd/acrylic air drying automotive refinish paints

middot;alkyd oxidative drying paints and varnishes



·two pack non-isocyanate coating technologies

*The liquid form of JADEWIN LS 123 also enables easy emulsification into water-borne systems.

*The performance of JADEWIN LS 123 can be significantly improved when used in combination with a UV absorber.

In Automotive coatings, combinations of JADEWIN LS 123 with the UV absorbers JADEWIN1130, JADEWIN UV 928, or JADEWIN UV 400 will significantly improve the weathering resistance and provide superior protection against gloss reduction, cracking, color change, blistering and delamination.

The light stabilizers may be added in two coat applications to both the base and the clear coat. In Wood Coatings, combinations of JADEWIN LS 123 with the UV absorbers. JADEWIN UV 384 or JADEWIN UV 1130 have been found highly effective in air drying alkyd based formulations.

The light stabilizer blends can be added to film forming finishes as well as decorative penetrating stains. The amount of JADEWIN LS 123 required for optimum performance should be determined in trials covering a concentration range.

Product description

ZION All purpose Adhesive is extremely strong, retains its strength and stays flexible. This polyurethane adhesive is classed as reactive adhesive. Typically reactive polyurethane adhesive can be showed strong adhesive strength as time goes on. Finally adhesive strength will last semi-permanently.Becausethese adhesives are manufactured by reacting mixtures of polyols with an excess of diisocyanate. The reaction of an isocyanategroup(-NCO) with an alcohol group(-OH) produces the urethane group(pre-polymer). The polyurethane pre-polymer includes from about 3% NCO to about 4% NCO. Isocyanate terminated polyurethane pre-polymer cured in the presence moisture. Moisture, which is present in the ambient atmosphere reacts with isocyanate end groups and this react will occur chain extension or crosslinking which will cause the curing reaction. This reaction can be showed strong adhesive strength as time goes on. A modern adhesive must have a long shelf life. Reactive adhesives meet this standard.

Our silyl modified polymer (SMP) with Case Number: 216597-12-5, has the same function with Kaneka MS polymer and STP-E (Silyl-terminated polyether) of Wacker. It is also known as SMP, MSP, STP, MS Polymer, Silane modified polymers, Modified silane polymers, Silane terminated polymers, Silyl modified polyether, Modified silyl polyether, Silyl terminated polyether.

High performance resin, silyl modified polymers (SMP) are multifunction-terminated groups with special functional groups involved. They have excellent comprehensive properties combining the advantages of silicone and polyurethane polymers. Silyl modified polymers (SMP) are characterized by their environment-friendliness, moisture curing, weather resistance, storage stability , easy processing, as well as isocyanate and solvent free traits.

As the raw materials in bonding, silyl modified polymer (SMP) Hiposil x-series are predominantly used in elastic hybrid sealants and adhesives with no health risks from solvents, isocyanates or tin, and therefore meet the requirements of green development. These hybrid adhesives and sealants made of silyl modified polymer (SMP) are usually applied in the scope of building & construction, transportation, general industry and DI Y.
