p-Chlorobenzotrifluoride (PCBTF)
Cl
CF3
• Only aromatic solvent that is VOC exempt.
• Excellent solvency & diluent properties with almost all
commercially available coating resins and co-solvents.
(solubility parameter = 8.6)
• PCBTF has low acidity ( < 3 ppm) and low moisture (<
150 ppm) and very stable structure for use in highly
urethane and epoxy systems
• Moderate flashpoint (43°C) and evaporation rate (.9)
slightly less than Butyl Acetate (1.0)
SPECIALTY GLYCOL ETHERS
OVER 40 SPECIALTY GLYCOL ETHERS
ETHERS BASED ON MEG, DiEG, TriEG,
Poly EG, PG, DiPG AND TriPG
Both mono-alkyl and dialkyl ethers available
For coatings requiring solvents with unique
balance of hydrophobic & hydrophilic
nature for superior coalescent,evaporation
and coupling properties
HDI Triisocyanurate
• Aliphatic Isocyanate for specialty urethane coatings to
improve weatherability and durability
• Available in trimer or triisocyanurate (100% solids) form
for handling & environmental safety
• New long term source to offset Lyondell’s recent USA
market departure

n = 5, 10, or 15
• Polymerizable surfactant
• Polyethylene monomethacrylate for increasing
hydrophilic properties in finished resins
• Further crosslinking of pendant hydroxy group possible
• Formed by ethoxylation of methacrylic acid, diester
content increases with chain length (for low diester
needs try the methoxy peg mono(meth)acrylates)
Hydroxyethyl Methacrylate
Acid Phosphate
O
O
(CH2 = C - C - O - CH2CH2 - O)n - P - (OH)3-n
CH3
n = 1 and 2 (mixture)
• Adhesion promoting monomer for metal and surfaces
• Acid functionality can be used for crosslinking reactions
• Under development is a 4-Hydroxybutyl analog for
better compatibility with more organophilic monomers
Methacrylamide
O
CH2 = C - C - NH2
CH3
• A low toxicity replacement for acylamide
• Generally used as low volume co-monomer to modify a
variety properties of different types of polymers
including acrylic, acrylonitrile, styrene, VCM, VAM and
butadiene based resins
• Produces lower viscosity and less water soluble resins
than acrylamide based resins
Isocyanatoethyl Methacrylate (MOI)

•
UNIQUE DUAL FUNCTIONAL MONOMER
Can be used to produce a variety of isocyanate functional
Resins or oligomers with a methacrylic backbone
Can alternately be used to form specialty methacrylate
functional monomers or oligomers
• Above reactions can be undertaken in relatively clean
manner with minimal side reactions or disruption of the
other functional group
