History
Since Dr. Bayer invented polyurethane (PU) foam in 1936,
2-component reactive liquid systems have played a critical
role in everyday industrial production. Apart from PU
foams and their derivative elastomers, reactive chemical
systems now include epoxies, acrylics, silicones, polysulphides
and polyesters. Their uses - in terms of bead, shot of
dot application - include bonding, sealing, structural
composite fabricating, encapsulating, impregnating, coating,
molding, mold-making and rapid prototyping through to
electrical, thermal and fire insulating.
Processing the 2-component reactive liquid systems involves
the accurate metering of both liquids in ratio to each
other prior to their being mixed together. Ratios are
by weight or volume and usually range from 1:1 to 10:1
according to their individual specification. After mixing,
resins may also require dispensing in a specific metered
volume or at specific metered rate.
As a result of a dramatic increase in resin usage, it became
vital to develop ways to simplify their packaging, storage,
handling and the final metering, mixing and dispensing process.
Since 1980, MIXPAC® Systems has been a leader in
the adhesive mixing and dispensing industry. Having emerged
from W.A. Keller Prozesstechnik, MIXPAC® was formally
launched in 1991 and is headquartered in Rotkreuz , Switzerland.
ConProTec Inc. is the North American operation with its
state-of-the-art facility located in Salem, NH, where
products are inventoried, maintained, customized, serviced,
and shipped.
Through a philosophy of continuous research and development,
MIXPAC® leads the global adhesive solution industry
by providing a constant stream of innovative solutions
for 2-component applications. All products are manufactured
in accordance with the ISO 9001 certification.
