Vinyl toluene (VT) is a defined mixture of methyl styrene isomers (meta and para) suitable for many different applications including coatings, polyester resins, adhesives, paper coatings and insulation resins. 
Partially or totally Vinyl toluene can replace Styrene in the coating and resins formulations. 
Studies show that VT has a better toxicological profile compared to styrene.

Vinyl toluene is similar to styrene in its toxicological properties. 
Fatty degeneration of the liver occurs in acute animal studies. 
Human subjects found the odor detectable at 50 ppm and objectionable at 300 ppm. 
Mainly an eye and respiratory tract irritant, it can cause central nervous system depression after absorption of high doses.
A skin, eye, and respiratory tract irritant; Inhalation of high concentrations may cause CNS effects; May cause liver injury; [ICSC] Vinyltoluenes, stabilized (UN2618) has warning of explosive polymerization;

Vinyl toluene is a mixture of m-methylstyrene and p-methylstyrene. Compared with styrene monomer (SM). 
Vinyl toluene has lower toxicity, volatility and odor, higher stability and flash point. 
Vinyl toluene can be used as a replacement of SM for the manufacture of unsaturated polyester resin, modified alkyd resin, vinyl resin and so on. 
These resins are widely used in impregnating insulation paint, coating and composite industries

The strong reducing agent Vinyl Toluene is a chemical category with characterics and manifestation of styrene and toluol. 
The colorless, flammable liquid is characterized by an annoying smell and is often used as a substitute for Styrene, if for the final products the content of volative organic compound is essential. 
At 54 Grad explosive vapours can arise.

Vinyl toluene is a colorless liquid having an aromatic odor. 
Vinyl toluene is usually sold as a functional monomer or as a mixture of isomers. 
Vinyl toluene is been used to modify alkyd resins since many years. 
The addition of vinyl toluene compound provides higher compatibility with both aromatic and aliphatic solvents which enhances the flexibility in formulating paints. 
Vinyl toluene is extensively used in the paints and coatings applications across various end-user industries.

Vinyl toluene is frequently used to dissolve varnishes and paints. 
Formulation of fast dry paints helps in producing paints and coatings for industrial indoor and other such applications. 
Fast drying of paints proves to be a vital factor in the application of these paints for these specific applications.
Paints and coatings formulated by vinyl toluene can be applied using various means such as spray, brush, dip, etc. 
This makes recoating the paint easy and also makes it useful particularly in refinishing and maintenance.

Improved solubility of vinyl toluene based alkyd resins can offer the paints formulators with several key advantages. 
Some of the key advantages include, formulation of fast dry paints with aliphatic solvents, formulation of fast dry paints which can be sprayed, rolled, brushed or dip applied, formulation of low odor and low cost fast dry paints and the formulation of coatings possessing excellent moisture resistance, hardness and gloss. 
Some of the major applications for vinyl toluene modified resins include machinery enamels, production line pre-finishing, primers, toy and hobby finishes, metal furniture, multi color finishes, industrial brushing enamels, hardware enamels, ink varnishes, oils for paper coatings, general purpose fast drying maintenance enamels and aerosols amongst others. 
Alkyds containing vinyl toluene can also be used as blending resins in some other systems in order to develop early hardness and speed up drying times.   

Vinyl toluene is used as an intermediate in the manufacture of plastics, coatings and insecticides. 
Critical effects of exposure are objectionable odour and eye and upper respiratory tract (URT) irritation. 
A poorly documented sensory irritation threshold is reported at 50 to 100 ppm in volunteers; in the same study, a nuisance odour at 200 ppm and strong irritation at 400 ppm are reported (ACGIH, 2018; DFG, 2017). 
Rodents are more sensitive than humans to URT irritation as evidenced in a chronic inhalation study, in which a LOAEC for damage to the nasal epithelium is reported at 100 ppm in rats and 10 ppm in mice (ACGIH, 2018; DFG, 2017). 
These results are supported by toxicological data for structurally related styrene, which indicate that local enzymatic oxidation produces irritating metabolites in rats, but not in human nasal tissue in vitro (DFG, 2017).
Both ACGIH (2018) and DFG (2017) recommend TWA equivalents based on a combination of the vinyl toluene-specific information and by analogy to the toxicological profile of styrene. 
Due to the recent amendment of the TLV-TWA for styrene to 20 ppm, ACGIH (2018) states the current TLV-TWA for vinyl toluene is under consideration. 
In view of this information, a TWA of 20 ppm is recommended to protect for mucous membrane irritation in accordance with the evaluation presented by DFG (2017). 
Severe irritation may be expected at acute exposures within an order of magnitude of this value. 
Therefore, a STEL of 40 ppm is recommended, which is below the sensory irritation threshold of 50 ppm in humans and supported by the DFG (2017) evaluation.

The objective of this project was to determine if vinyl toluene monomer could be substituted for styrene monomer at various levels, in an isopolyester resin, without a loss of physical properties or a reduction in its corrosion resistance. 
An isopolyester corrosion resin was synthesized in our pilot plant and dissolved in styrene monomer, vinyl toluene monomer, and blends of both monomers. 
Liquid resins and clear cast properties were determined by conventional SPI and ASTM test methods. 
Composites (using ASTM C581 construction) of these resins were prepared and one year immersion testing in five different media was initiated. 
One year testing of these composites has been completed.

Vinyl toluene is a colorless liquid with a sturdy, unpleasant odor. 
Mainly used as a monomer in the manufacture of plastics and have wide applications in paints and surface coatings industries. 
Further, it acts as an intermediate in the synthesis of certain pesticides.

Vinyl toluene can be used in any formulation in which styrene is commonly used, like alkyds and unsatured polyester resins (UPR). 
Vinyl toluene helps to improve chemical and physical properties of the coating: 
improved drying characteristics, higher temperature stability, less shrinkage, improved caustic resistance and improved acid resistance.
Vinyl toluene also is less volatile than styrene, thus it helped in reducing emissions helps to meet national regulations on working place concentrations.
