Polychloroprenes for solventborne adhesives
Under the product name
Baypren®, Bayer markets a polychloroprene (poly-2-chlorobutadiene-1,3),
produced by a state-of-the-art process.
Properties: The Baypren® grades differ with
regard to their crystallization rate and solution viscosity. The
200 range has a medium crystallization rate and the 300 range a
fast crystallization rate. As far as the solution viscosity is concerned,
we offer Baypren® grades with viscosities between 10 and 120
mP...s. Apart from their viscous properties, polychloroprene solutions
also have elastic properties. In addition, the product range includes
Baypren® grades both with and without thiuram. Adhesives based
on Baypren® are noted for their long open time and the high
initial strength of the bonds.
Uses: Baypren® is ideal when high initial strength is
needed and/or the bonded articles have to be subjected to further
treatment very quickly. Typical fields of application include the
bonding of skirting boards and the laying of floorcoverings in critical
areas (e.g. stairs). We recommend thiuram-free Baypren® grades
especially for bonding sensitive, light colored materials.
Advantages:
- High dissolving rate
- Very high initial strength

our technical experts will be pleased to give detailed advice on specific
applications and on the formulation of adhesives with the Baypren®
grades.
