| NEOL® Neopentylglycol
(2, 2-dimethyl-1, 3-propanediol) is a unique diol offering superior
performance advantages in many end-use applications. These advantages
are derived from its chemical structure. The location of the hydroxyl
groups on primary carbon atoms allows rapid esterification. Additionally,
the two methyl groups, instead of the usual two hydrogen atoms, on
the alpha carbon atom are responsible for the high chemical and thermal
stability of NEOL® Neopentylglycol and it
derivatives.
NEOL® Neopentylglycol is a valuable chemical
intermediate used in the production of saturated and unsaturated polyester
resins. Some examples include alkyd
coating resins, powder coating
resins, gel coat resins, resins
for fiberglass reinforced systems, polyester
polyols, plasticizers and resins
for synthetic lubricants.
Applications |
| |
| Alkyd
Coating Resins |
| NEOL® Neopentylglycol is used
to produce saturated polyester resins that are formulated into oil-free,
high- and low-solids, alkyd coatings. These coatings are characterized
by a superior balance between hardness and flexibility and are more
stable to heat and ultraviolet radiation than resins manufactured
form other glycols. Important applications include metal furniture,
appliance, automotive, coil and varnish coatings. |
| |
| Powder
Coating Resins |
| Like alkyd coatings, powder coatings are characterized
by superior hydrolysis resistance, good weatherability and good hardness/flexibility
balance. In powder coating formulations, NEOL®
Neopentylglycol offers the additional advantage of providing small
differences between the glass transition temperature and melting point.
Important areas of application include general metal, appliance, metal
furniture, automotive and machinery coatings. |
| |
| Gel
Coating Resins |
| NEOL® Neopentylglycol allows
for the production of high quality gel coat resins with high molecular
weights for superior hydrolytic and chemical stability and exceptional
corrosion resistance. Applications include marine accessories, general
construction, bathroom and kitchen fixtures, corrosion resistant tanks,
pipes, ducts and many others. |
| |
| Fiberglass
Reinforced Resins |
| NEOL® Neopentylglycol is used
in fiber glass reinforced resins that offer high impact strength and
flexibility, outstanding dielectric properties, high mechanical stability
and malleability. They also offer good chemical resistance, good light
transmission and low thermal conductivity. They are used in the same
areas of application as gel coats, along with recreational consumer
goods and electrical components. |
| |
|
Polyester Polyols |
NEOL® Neopentylglycol-based
polyester polyol resins are an important starting material for non-foaming
polyurethanes. These resins provide good hydrolytic stability, lower
glass transition temperatures, lower melting points and thermal,
uv and chemical resistance. Important areas of application include
thermoplastic polyurethanes, coatings, cast elastomers and adhesives.
|
| |
| Plasticizers |
| NEOL® Neopentylglycol is used
to manufacture polyester plasticizers that are used mainly to modify
polyvinyl chloride (PVC) resin systems. When blended with NEOL®
Neopentylglycol-based polyester plasticizers, PVC resin systems exhibit
superior low temperature properties while retaining low volatility
with high resistance to migration and loss of flexibility. |
| |
|
Synthetic Lubricants |
NEOL® Neopentylglycol is
used to manufacture diester resins used in the production of synthetic
lubricants. These lubricants exhibit superior thermal and oxidative
stability, low solidification points, high viscosity indices and
high flash points.
