A silicone pressure sensitive adhesive composition is curable to form a silicone pressure sensitive adhesive. The silicone pressure sensitive adhesive composition can be coated on a substrate and cured to form a protective film. The protective film can be adhered to an anti-fingerprint coating on display glass, such as cover glass for a smartphone.

Block-modified polysiloxanes and compositions comprising the block-modified polysiloxanes are useful in the field of textile finishing. Emulsions comprising the compositions have a very small and narrowly distributed particle size which increases penetration, and provide good softening properties coupled with good hydrophilicity.

The invention relates to a process for preparing a polyurea or a polyurethane organopolysiloxane block copolymer having a silicone content of at least 90% in weight relative to the total weight of the organosiloxane block copolymer. The invention further relates to a polyurea or a polyurethane organopolysiloxane block copolymer obtained according to this process and its use in a method for manufacturing a 3D article by an additive technique.

A networked silicone is disclosed. The networked silicone comprises crosslinked strands of looped organosilicon compounds. A composition for preparing the networked silicone is also disclosed, and comprises (A) a looped organosilicon compound, (B) a crosslinking organosilicon compound, and optionally (C) a catalyst. Additionally, a method of preparing the networked silicone is disclosed, and comprises reacting the looped organosilicon compound (A) and the crosslinking organosilicon compound (B), optionally in the presence of the catalyst (C), to give the networked silicone. A reaction product comprising the networked silicone is also disclosed. The reaction product is prepared from the composition and/or in accordance with the method, and may be a cured product. Additionally, a composite article and a method of forming the same are disclosed. The composite article is formed by disposing a networked silicone composition on the substrate and curing the networked silicone composition, thereby preparing the composite article.
