The present disclosure provides a hot melt tape at least including a substrate, an adhesive layer, and an anti-sticking layer, wherein the anti-sticking layer is adjacent to the adhesive layer and is the outermost layer of the hot melt tape. The hot melt tape may be used to seal objects, and preferably is made of a multilayer co-extrusion process. The anti-sticking layer prevents the hot melt tape from sticking the objects without needing a release film, and the hot melt tape can be directly heated during sealing the objects.

Release layers that include an oligomeric component comprising a unit of the Formula (I) are useful for releasably transferring components from one surface to another during manufacturing of microelectronic devices.

A curable polysiloxane release coating composition comprises (A) an organopolysiloxane containing ethylenically unsaturated groups. Component (A) is selected from: (A1) a branched organopolysiloxane containing at least three (3) organopolysiloxane branch chains linked through a central core including at least two (2) organopolysiloxane branch chains each of which contain an ethylenically unsaturated group; and/or (A2) a linear organopolysiloxane containing at least 2 ethylenically unsaturated groups having at least six (6) carbon atoms. The composition further comprises (B) an organopolysiloxane containing at least 2 Si—H groups, and (C) a hydrosilylation catalyst. The composition yet further comprises (D) a hydrosilylation inhibitor comprising a maleimide of the general formula (I):

In formula (I), A.sup.3 represents a hydrogen atom or a hydrocarbyl or substituted hydrocarbyl group having 1 to 18 carbon atoms, and A.sup.1 and A.sup.2 each represent a hydrogen atom or a hydrocarbyl or substituted hydrocarbyl group having 1 to 18 carbon atoms.

Provided is a multi-layered anisotropic conductive adhesive including an upper conductive adhesive layer, a conductive fabric layer with two sides and a lower conductive adhesive layer, wherein one side of the conductive fabric layer is plated with metal. In the application of a flexible printed circuit, reinforced parts, formed by laminating multi-layered anisotropic conductive adhesive with steel or polyimide-type stiffener, can effectively prevent the deformation of installed parts due to warping, and ensure the good hole filling, good direct grounding effect, and good shielding performance. Therefore, the multi-layered anisotropic conductive adhesive has good electrical properties, good adhesive strength, better tin soldering, reliability and flame resistant. Also provided is a method of producing the multi-layered anisotropic conductive adhesive.

Peel-away tape includes a double-sided adhesive tape with a perforated design and a peel-away backing that includes liftable tabs to assist in the removal thereof. In an exemplary embodiment, the tape and peel-away backing is perforated on equidistant intervals. A small tab located at the center of each perforation extends over the perforation line which, when separated, extends outward where it can be grasped.

Described herein are methods of forming uncured sealant assemblies and also methods of forming seals between various parts using such assemblies. In some examples, an uncured sealant assembly comprises two protective layers and an uncured sealant layer, disposed in between. The uncured sealant assembly is stored and provided at a cure-inhibiting temperature, selected to minimize the curing rate of the uncured sealant layer. The size and the shape of the uncured sealant layer are specifically selected to ensure the complete coverage of the faying surfaces, filling of all gaps and voids between the faying surfaces, and controlling the shape and size of uncured sealant squeeze out between the faying surfaces. In some examples, the size and shape of the uncured sealant layer maybe be specifically selected to have no uncured sealant squeeze out between parts.

Provided is a polyorganosiloxane release coating composition, including: (A) an aryl-functional polydiorganosiloxane having a content of aliphatically unsaturated groups, (B) a polyorganosilicate resin having silicon bonded alkenyl groups, (C) a polyalkylhydrogensiloxane, having at least two silicon-bonded hydrogen atoms per a molecule, (D) a hydrosilylation reaction catalyst in a catalytic amount, (E) a hydrosilylation reaction inhibitor, (F) an anchorage additive, and optionally (G) a solvent; where the composition is free of polydiorganosiloxanes that do not have silicon bonded aryl groups, other than starting material (A). Also provided are a method for preparing a release liner(100) with a release coating(101) and the prepared release liner(100).

A biodegradable display protector comprises a top layer; an antimicrobial (AF) layer beneath the top layer; a core layer formed of biodegradable material beneath the AF layer; an adhesive layer beneath the core layer; and a bottom release layer beneath the adhesive layer. The bottom release layer may be peeled off to allow the screen protector to be adhered to a display screen. In the embodiments, biodegradable polyethylene terephthalate (PET) or biodegradable polylactic acid (PLA) may be used for an inflexible protector whereas biodegradable thermoplastic urethane (TPU) may be used for a flexible protector. A thickness of the screen protector may be between about 0.08 mm to about 0.23 mm.

Adhesive articles with strippable liners are described. In particular, adhesive articles including an optional substrate having a first and second major surface, an adhesive layer provided on the first major surface of the substrate, and a strippable liner in contact with the adhesive layer including a polymer layer including polybutylene succinate and from about 0.5 and about 5 polymer weight percent of a plant-based wax are described. Liners from such articles may exhibit good release performance while being compostable.

A biodegradable cellulose fiber-based substrate, at least one side of which is coated with a release coating including: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, and b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms. The biodegradable substrate is certified biodegradable in accordance with EN 13432. A method of production thereof is also disclosed.
