Michelman launches low
VOC Michem Wood Coating 75
Michem Wood Coating 75 from Michelman is a new water-based additive that
penetrates wood surfaces and produces
excellent water beading and anti-swell
properties. When compared to uncoated
wood, Michem Wood Coat 75 improves
swell resistance by 80 percent, and extends the life and beauty of exterior wood
the company said. It dries completely clear
and is typically used for outdoor wood
deck and fence applications. Michem
Wood Coating 75 contains less than 100
grams per liter of VOCs and can be diluted down to 10 percent solids while
maintaining effectiveness. It offers outstanding recoatability for improved
wetout andintercoat adhesion, and can be
used as a stand-alone topical wood coating or as a surface modifier. Because it
protects against water damage, Michem
Wood Coating 75 also contributes to the
ability to control cracking, splintering,
color fading, dirt pickup, mold and
mildew growth.
BYK-P 9085 processing additive
provides mold release and
surface enhancing
BYK-P 9085 was developed for Low Profile and Class A SMC systems. It stabilizes
the compound and improves flow behavior. Because of its mold-release properties,
BYK-P 9085 replaces the traditional
mold-release products the company said.
BYK-P 9085 improves the surface quality
of the molded part. It also improves the
paint adhesion and the bondability of the
molded parts. BYK-P 9085 affects thickening. An additional 10 percent MgO
may be needed to achieve thickening
properties comparable to the Zn/Ca
stearate system.
Lubrizol unveils Carbocure
7000 liquid surface modifiers
for wood coatings
The Lubrizol Corporation has intro-
duced Carbocure 7000 to the wood coatings market. Carbocure 7000 is part of a
new generation of liquid surface modifiers developed specifically to improve
the performance and aesthetics of UV-coated wood products. Using proprietary
Lubrizol technology, Carbocure 7000
displays excellent matting and tactile
properties without increasing formula
viscosity or affecting clarity, making it an
ideal and versatile choice for high-end
furnishings and other demanding flat-surface coating applications. Carbocure
7000 creates a smooth, uniform matte
appearance with a soft touch and low
haze. Carbocure 7000 is in liquid form
and features quick, agglomerate-free dispersion. It is easy to use and incorporate
at any stage of the coating production
process. In addition, this new surface
modifier offers improved water beading
capability and exhibits no issues relating
to foaming or dust.
Hoffmann introduces Silfit Z
91, Aktifit AM and Aktifit VM
siliceous fillers
Hoffmann Group introduced its products
Silfit Z 91, Aktifit AM and Aktifit VM for
applications in elastomers, paint and varnish, and thermoplastics. Silfit Z 91 is a
naturally occurring conglomerate of
amorphous and crypto-crystalline silica
with lamellar kaolinite, which has been
subjected to a heat treatment. The components and the thermal process lead to a
calcined product that offers special performance benefits as a functional filler.
Aktifit is an activated Silfit Z 91, produced
by modifying the surface with functional
silanes. The by-products split off during
the treatment reaction are largely removed
during the production process, which
firmly attaches the silane to the filler surface. This helps minimize undesirable side
effects, as they are potentially encountered
with insitu mixing (direct addition of
silane to the compound).
Dow offers hiding Op TiO2nizer
reformulation tool
A new reformulation tool from Dow
Coating Materials is helping paint formulators and the coatings industry find
new and improved opportunities to save
on TiO2 with Ropaque Opaque Polymer
replacement. The Dow Hiding
OpTiO2nizer Reformulation Tool uses
key inputs to calculate reformulations
using less TiO2 and estimates the associated cost savings for formulations while
maintaining dry hiding performance and
equal tint strength. Dow Research Scientist, David Fasano, who developed the
tool, points to rising TiO2 cost as a
major incentive for reformulating with
Ropaque Opaque Polymer. In high-qual-ity flats, the optimum level of TiO2 replacement with Ropaque Opaque
Polymer can be more than twice what it
was a few years ago, and the savings potential has gone from about 10 to more
than 40 cents per gallon. There is also
room for TiO2 savings and added value
in low-level TiO2 paint formulations,
such as mid-tones, primers and economy
interior flats the company said. The Hiding OpTiO2nizer Reformulation Tool
factors in the cost of TiO2, Ropaque
Opaque Polymer, extenders, binder, dispersant and coalescent. It offers close to
200 options for formulators to customize formulations using different levels of TiO2 reduction and fraction of
critical PVC in addition to different
ways to balance extenders. To help guide
formulators, the tool also has the ability
to recommend options based on desired
sheen. These recommendations are based
on data compiled by Dow collected over
more than 30 years of Ropaque opaque
polymer formulation experience. In addition to enabling adjustments to extender, coalescent and dispersant levels, the
Hiding OpTiO2nizer Reformulation
Tool estimates gloss changes and recommends flatting extender as needed. Cost
