An environmentally favorable method is described for treating an incandescent lamp with a heat curable substantially organic solvent free silicone composition to improve the shatter resistance of the lamp.

Shatter-resistant incandescent lamp, silicone coating composition, and method

The present invention provides novel vinyl containing organopolysiloxane elastomers which possess excellent low compression set and heat aging characteristics and which can advantageously be formulated into liquid silicone elastomer moldable compositions.

Low compression set silicone elastomers

Secondary contact adhesion or self-bonding in cured liquid injection molding silicone compositions is reduced by the inclusion in the composition of an inhibitor compound selected from the group consisting of phenyl fluids, titanate esters, and silicate esters.

Heat curable elastomeric compositions

An extrudable composition formed of a blend of a polymer and a finely divided filler is prepared by combining the materials under conditions of high shear forces resulting in a composition which when diluted to a selected level has an application rate which is relatively higher than a composition having the same relative proportions of polymer and filler combined under conditions of low shear, the high shear forces reducing the aggregate size. The invention is also directed to a method for reducing the initial average aggregate size of a filler dispersed in a polymer by subjecting the mixture to high shear forces in a high intensity mixer.

High application rate extrudable polymers and method of manufacture

Low viscosity elastomeric silicone foam compositions are produced which do not bleed, split or rupture with cure where viscosity is controlled by controlling the content of the vinyl containing polysiloxane portion of the foam.

Low viscosity silicone foam compositions

Amine compounds are added to foamable elastomeric silicone foam to reduce foam density.

Low density silicone foam

Treated filler having surface nitrogen groups is added to silicone foam to reduce density.

Novel UV-curable silicone release coating compositions and photocatalysts therefor are provided which include hydrogen-functional and vinyl-functional photoreactive terpolymers, which are especially compatable with certain perbenzoate ester photocatalysts. The addition of certain polyaromatic photosensitizers to enhance cure is also disclosed.

Ultraviolet radiation-curable silicone release compositions

Novel UV-curable silicone release coating compositions and photocatalysts therefor are provided which include mercaptoalkoxyalkyl-functional polysiloxanes and vinyl-functional photoreactive terpolymers, both of which are especially compatable with certain perbenzoate ester photocatalysts. The addition of certain polyaromatic photosensitizers to enhance cure is also disclosed.

Ultraviolet radiation curable silicone release compositions

There is provided a new improved dampening medium for a shock dampening device. The dampening device comprises a closed chamber, a movable piston rod extending through the chamber and an enlarged piston head located on the piston rod. Located in the interior space of the closed chamber under pressure is a compressible solid, fragmented, particulate mass of cured unfilled silicone rubber composition for producing a damping effect on the piston rod and head. The damper device includes a threaded plug for varying the internal static pressure on the compressible mass within the chamber and apertures extending through the piston head or an annular space between the outer edge of the piston head and the interior of the chamber for bypassing the compressible mass.
