The present invention relates to a curable adhesive composition based on acetoacetate compound, and to its use in multi-purpose bonding applications. In particular, the present invention relates to a curable adhesive composition based on a multifunctional acetoacetate compound and polyoxyalkylene polyamines.

Curable adhesive composition for multi-purpose bonding applications

The present invention provides a membrane filtration module comprising a housing in which the filtration membrane is disposed in a fixed positional relationship by a potting or bonding material obtained by the curing of a two component (2K) composition consisting of: a first component (A) comprising at least one compound (a) having at least two acetoacetate functional groups; and, a second component (B) comprising at least one compound (b) having at least one amino group, each said amino group being a primary or secondary amino group.

Potting or bonding composition for filtration membrane modules

The present invention relates to a polyurethane laminating adhesives, methods for producing a multilayer laminate by laminating at least two films with a polyurethane laminating adhesive, and multilayer laminates obtainable by these methods wherein the polyurethane laminating adhesive comprises an NCO-terminated polyurethane prepolymer obtainable by reacting a polyol mixture comprising: 0.1 to 20.0 wt % relative to the total weight of the polyol mixture of at least one polybutadiene polyol; and 5.0 to 99.9 wt % relative to the total weight of the polyol mixture of at least one polyether polyol, wherein the at least one polyether polyol comprises at least one polyether polyol with a number average molecular weight Min the range of &#x3e;1000 g/mol to 10000 g/mol; with at least one polyisocyanate, wherein the at least one polyisocyanate is used in an amount such that the isocyanate groups are present in molar excess relative to the hydroxyl groups of the polyol mixture. Also encompassed are the use of the described adhesives for laminating two or more films, and the multilayer laminates obtainable by the described methods.

Polyurethane adhesives for bonding low surface energy films

The invention relates to the use of a solvent-free, 2 component adhesive for adhering sterilizable composite films, wherein the adhesive comprises a component A made from at least one pre-polymer comprised of NCO groups, said pre-polymer produced from low molecular weight polyether alcohols, polyester alcohols and/or polyalkylene alcohols having a functionality of 2 or 3, implemented having a high molar excess of TDI and removal of the unimplemented monomer diisocyanate, and a component B comprising at least one 2 or 3 functional polyesterpolyol, produced from diols and/or triols on the basis of polyethers or polyalkylene diols implemented having dicarboxylic acids and derivatives thereof, wherein at least 10 to 40 wt % must be comprised of aliphatic Cto Cdicarboxylic acids, and auxiliary and additive materials in at least one component A or B.
