PEP SETTM BLUE

VOC-REDUCED POLYURETHANE
NO-BAKE BINDER SYSTEM WITH
IMPROVED CLASSIFICATION
Odor pollution is a significant challenge in foundries.
When mixing and mold making in particular, unpleasantodors can be produced, making it uncomfortable for
employees to work. In addition to the health aspect,sustainability and the possibility of reducing emissions inproduction are becoming increasingly important.
Thanks to the state-of-the-art development PEP SETTM
BLUE, the polyurethane no-bake binder system does notcontain any hazardous ingredients in the Part 1 resin.
Part 1, which is label-free, has therefore much less odor.
With its latest development PEP SETTM BLUE,
ASK Chemicals thus offers a solution to reduce odors inthe foundry and to protect employees. Thanks to BLUE
technology, PEP SETTM BLUE offers high productivity
and improved occupational safety at the same time.
Another advantage of PEP SETTM BLUE is environmental
friendliness with a significantly lower content of harmfulmonomers (especially phenol) and a reduction in VOCemissions.

Modern Polyurethane No-Bake System
Following the successful development in the field of
polyurethane cold box technology, ASK Chemicals hasdeveloped two new systems: PEP SETTM SILVER andPEP SETTM BLUE.
PEP SETTM SILVER is a binder system with a very low
proportion of harmful monomers, especially phenol. This,
combined with low EH&S (Environment, Health & Safety)
impact solvents, makes PEP SETTM SILVER a polyurethane
no-bake (PUNB) system that provides enhanced hazard
labeling. The reduction of phenol in the formulation
improves the foundry‘s emission load and reduces thephenol pollution in the used sand. It also offers many otheradvantages: high productivity, good strength development,
good mechanical reclamation of the used sand, lowsmoke development when pouring and low odor pollution
when mixing and molding.
Environmentally friendly PEP SETTM BLUE
With the new PEP SETTM BLUE, ASK Chemicals is now
taking another step towards more environmentally friendly
PUNB binder systems. THE PEP SETTM BLUE technology
also has a very low free formaldehyde and phenol content,
which can also significantly reduce the phenol pollution in
the used sand. In addition, the PEP SETTM BLUE dispenses
with aromatic solvents. Due to the exclusive use of solventswith a low EH&S impact, the PEP SETTM BLUE part 1 resin
does not require hazard labeling. The odor during mixingand molding can thus be further reduced. In addition, thereactivity of the PEP SETTM BLUE technology is adjustable
over wide ranges with a comprehensive selection ofcatalysts.
Low VOC PUNB binder
PEP SETTM BLUE dispenses with aromatic solvents and, incombination with the very low free phenol content, offers
foundries the opportunity to reduce VOCs and BTX. Phenol
reduction facilitates waste sand processing and reduces
landfill costs. Part 1 resin of the 3-part PEP SETTM Systems

is not subject to hazard labelling requirements.
Less hazard labeling and more occupational healthand safety
The low-phenol PUNB technologies PEP SETTM SILVER
and PEP SETTM BLUE cover various aspects ofenvironmental protection and occupational safety. While
the strengths of the PEP SETTM Silver lie in the easymechanical reclamation of the used sand and the low
smoke production during casting, the new PEP SETTMBLUE is particularly characterized by the label-freePart 1 resin and an even lower odor production during
mixing and molding.
