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 topside protective film. The topside protective film can be used to protect an anti-fingerprint hard coating in a screen protective film on cover glass for a display device, such as a smartphone.

A curable composition contains: (A) a polydiorganosiloxane component including: (A1) greater than 3.1 wt % to 20 wt % of an aliphatically unsaturated polydiorganosiloxane polymer and (A3) a hydroxyl-terminated polydiorganosiloxane gum of unit formula (A-III); (B) a polyorganosilicate resin component including (B1) a capped resin, (B2) >18.53 wt % to 54.3 wt % of an uncapped resin; where the weight ratio of the uncapped resin (B2) to the capped resin (B1) is greater than 0.51 to 58.82; where component (A) and component (B) are present in amounts to provide a weight ratio of (B):(A) of 1.2:1 to less than 1.62:1; (C) a polyorganohydrogensiloxane that is present in an amount to provide a molar ratio of silicon bonded hydrogen atoms to alkenyl groups for the curable composition of 5 to 50; (D) a hydrosilylation reaction catalyst in an amount sufficient to provide 1 to 1000 ppm of platinum group metal; and (E) a condensation reaction catalyst; where the content of alkenyl groups in the curable composition is 0.017 wt % to 0.089 wt %; and where wt % values are relative to the total weight of components (A), (B), (C), (D) and (E) unless otherwise stated.

Curable composition for silicone pressure sensitive adhesives

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.

Silicone pressure sensitive adhesive composition and methods for the preparation and use thereof

A silicone pressure sensitive adhesive is prepared by curing a radical reaction curable composition. The silicone pressure sensitive adhesive adheres to various silicone elastomers and is useful in preparation of components of flexible display devices.

The objective of the present disclosure is to provide a method, apparatus and system of ACK/NACK reporting for Cat-M mechanism. Here, a user equipment feeds back an ACK/NACK message to an eNB on PUSCH based on received downlink data, wherein when computing the number of resource elements occupied by the ACK/NACK message on PUSCH, the number of OFDM symbols in a guard period is ruled out. This may effectively lower the UE's PUSCH data code rate, and meanwhile enhance the eNB's decoding performance on PUSCH.

Method, apparatus and system for ACK/NACK reporting

A solventless silicone pressure sensitive adhesive composition includes: (A) a polydiorganosiloxane having a monovalent hydrocarbon group with terminal aliphatic unsaturation, (B) a branched polyorganosiloxane having a monovalent hydrocarbon group with terminal aliphatic unsaturation, (C) a polyorganosilicate resin, (D) an olefinic reactive diluent, (E) a polyorganohydrogensiloxane, (F) a hydrosilylation reaction catalyst, and (G) an anchorage additive. This solventless silicone pressure sensitive adhesive composition can be cured to form a pressure sensitive adhesive. When cured on a backing substrate, the resulting adhesive article is useful for protecting electronic devices during fabrication, shipping, and use.
