Baypren is a 2-chlorobutadiene-(1,3) poly- mer (polychloroprene) produced by the most up-to-date processes.
To enable the widely differing requirements of the adhesives industry to be fully met, the Baypren range consists of grades with differ- ent crystallization rates and solution viscosi- ties.
Adhesives based on Baypren are distin- guished by their long open times and high initial strength. They are sometimes com- bined with Desmodur to form two-compo- nent adhesives. Baypren adhesives have a very wide range of applications and have be- come indispensable in the footwear, furni- ture, construction and automotive industries and for DIY applications.
Butyl is the trade name for copolymers of isobutylene, isoprene and divinyl benzene.
The butyl grades differ in their crosslinking level. They are also available preformulated with filler and plasticizer.
Butyl adhesive sealants
Adhesive sealants based on butyl are noted particularly for their water and gas imperme- ability, weather stability, ozone resistance and heat stability. They have excellent adhe- sion to glass, metal and many other materi- als. They can be mixed with large amounts of fillers and plasticizers and still retain their good elastomeric properties. Vulcanization with peroxide is possible. They are typically used in building, car pro- duction and the electrical industry.
Desmocoll is the trade name for predomi- nantly linear hydroxyl polyester polyure- thanes.
Desmocoll grades are manufactured with dif- ferent solution viscosities, thermoplasticities and crystallization rates to ensure that the wide-ranging requirements of the adhesives industry can be met.
