DMS is a colourless transparent liquid that dissolves in no polar solvents such as ethyl ethers and slightly in water and is used in the production of HALS systems. HALS are radical scavengers used to protect polymer coatings from photo-oxidation damage and thus reduce the deterioration of materials. It is used in paint strippers and with a number of resins including acrylics, alkyds, polyesters and polyurethanes. It is a good alternative to acetates, dichloromethane, glycol ethers and n-methyl-2-pyrolidone.
Applications
- Paint Additives
- Printing inks
- HALS
- Paint strippers

A range of photoinitiators
react with monomers and / or oligomers to initiate polymer chain growth. The UV initiator
system is critical because it determines the UV-curing speed and significantly affects the
comprehensive performance of cured materials such as yellowing, odor, migration from cured
film and so on. They are essential ingredients of all UV-curable adhesives, inks and coatings.

Benzoin Acrylate
VICURE 25 is a white crystalline solid used as a copolymerisable photoinitiator. It is an efficient UV radial photoinitiator for polymerization and crosslinking of mono- and multifunctional unsaturated monomers which activates at 250 nm wavelength, widely used for (meth)acrylate polymerization used in pressure sensitive adhesives and can also be used for UV curable inks.
CAS 56467-43-7
4-Benzoylphenyl Methacrylate
VICURE 40 is a white to light yellow powder used as a copolymerisable photoinitiator. It is a benzophenone functionalized monomer used as an efficient UV radical photoinitiator for polymerization and crosslinking of block copolymers that activates at 255 nm wavelength, widely used in UV curable compositions and inks.

co-dispersant for pigments, promotes acceptance of colorants, contributes to pH stability, low odor, and good anticorrosive properties
A range of binders
tetraethylorthosilicate and another form of high purity amorphous silica.
- Increased stability in store. The change in viscosity during the first 6 months is minimal.
- Increased stability in the slurry mix. This enables close control of viscosity and density
and prolongs the useful life of the slurry. - More filler is taken up in the slurry mix for the same viscosity.
- Bonding strength from the available silica is higher.
- Mold coats air dry quicker.
- In ceramic molds process.
- Investments foundries, both in mechanical and manual molding systems.
- In anticorrosion paints such zinc-rich paints and shop primers typically used for bridges,
ships and structural steel in severe environments. - In refractory products.
For optimum stability the pH of slurries should be maintained at 1.0-
1.5 by adding 10% weight/volume of sulphuric acid in alcohol, and the slurry temperature
should be maintained at 20°C±1°C. Viscosity and density should be checked twice daily.
Binder and filler should preferably be pre-mixed in a separate tank for topping up the main
tank. Losses of volume due to evaporation of solvent should be made
up by adding alcohol. The tanks should be left covered when not in use.
