A bonded multilayer article including: (a) at least one first layer of a silicone-containing rubber substrate material bonded to (b) at least one second layer of a substrate material bondable to the first layer; wherein at least a portion of the surface of the first layer is activated for adhesion to increase the bond strength of the first layer to a second layer such that the bond strength of the first layer bonded to the second layer is increased; and a process for producing the above bonded multilayer article.

Bonded multilayer article

The present invention relates to a method of coating a pipeline field joint comprising the steps of (a) applying a layer of a coating material composition comprising (i) a propylene polymer and (ii) a substantially linear ethylene copolymer, a linear ethylene copolymer, or mixtures thereof, to the uncoated region of the field joint, preferably the coating is applied by injection molding.

Method for coating a pipeline field joint

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polymer polyol which has a liquid polyether polyol as a continuous phase and polymer particles dispersed in the liquid polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Syntactic polyurethane elastomers for use in subsea pipeline insulation

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol having a low amount of terminal unsaturation, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Syntactic polyurethane elastomers based on low unsaturation polyols for use in subsea pipeline insulation

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer is characterized morphologically by the presence of small discrete morphological domains 0.1 to 3 &#x3bc;m in diameter, and the substantial absence of discrete morphological domains 5 to 30 &#x3bc;m in diameter. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Syntactic polyurethane elastomers having distinct morphology for use in subsea pipeline insulation

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a prepolymer made from a polyether polyol and a polyisocyanate, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.
