Abstract: Polyvinyl carbamates having more than five carbon atoms in the alkyl groups attached to the carbamate side chains are coated on to material and used as a removable line to prevent adherent rubber surfaces firmly adhering to themselves or another surface. The polyvinyl carbamates are prepared by reacting polyvinyl alcohol or a hydrolysed vinyl acetateethylene copolymer with an isocyanate such as heptyl, octyl, decyl, dodecyl, tetradecyl and octadecyl isocyanates. Cross linking of a polyvinyl carbamate having residual hydroxy groups may be effected by reacting with a diisocyanate. Solutions of the carbamate in benzene or toluene may be used to coat paper, cellulose derivatives and polyvinyl resins. The coating may comprise up to 95 per cent of ethyl cellulose, polyvinyl acetate or butyral, rubber latex, ester gum, butadiene-styrene and ethyl-butyl acrylate-ethyl acrylate copolymers, terpene resin and hydrogenated indene-coumarone resin.

Abstract: In order to reduce adhesive residue of an adhesive tape, an adhesive tape is provided, including a base material 10 having a base fabric 1 composed of warps and wefts, a first laminate layer 2 formed on a first surface 1A of the base fabric, and a second laminate layer 3 formed on a second surface 1B of the base fabric; and an adhesive layer 6 formed as an outermost layer on the side of the base material 10 on which the first laminate layer 2 is formed, wherein an unevenness 2B formed due to the warps and the wefts is formed on a surface of the first laminate layer opposite to the base fabric.

Abstract: A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer formed from a fluorine resin, a substrate layer, an adhesive layer, and a release liner formed from polyethylene terephthalate (PET) in this order in a laminating direction. The process film is formed from at least of polyethylene terephthalate (PET), polyolefin, and polyvinyl chloride (PVC), and is thinner than the release liner.

Abstract: A method for transferring an adhesive layer of thermoplastic polymer(s) from a first substrate to a second substrate including: depositing an antiadhesive layer on a first substrate, this layer being deposited on the periphery of the top face of said substrate, referred to as peripheral layer, thus providing on said top face a zone devoid of said layer, referred to as central zone; depositing an adhesive layer of thermoplastic polymer(s) on said central zone; depositing an antiadhesive layer on a second substrate, this layer being deposited on the top face of the second substrate excluding its periphery, said periphery being thus devoid of said antiadhesive layer; bonding the first substrate and the second substrate consisting of thermocompressing the top face of the first substrate onto the top face of the second substrate; removing the first substrate, whereby the second substrate remains, of which the top face is coated by the adhesive layer of thermoplastic polymer(s).

Abstract: Provided is a composition with a viscosity in which coating is possible even with a small amount of solvent, has excellent curability, and in which an Si-based pressure-sensitive adhesive (PSA) (e.g., PSA layer) formed by a curing reaction has a low (e.g., 50° C. or lower) glass transition temperature (Tg) despite having high PSA strength and tack, has favorable wettability, and has favorable mechanical strength and elongation; and an application of the same. A low/solvent-free silicone PSA composition comprises: (A) a chain organopolysiloxane having an aliphatic unsaturated carbon-carbon bond-containing group only on a molecular chain end, (B) a straight-chain organohydrogenpolysiloxane having Si—H only on both ends, (C) an organopolysiloxane resin with a weight average molecular weight that is less than 5000, (D) an organopolysiloxane having one or more aliphatic unsaturated carbon-carbon bond-containing groups at locations other than an end and three or more in a molecule, and (E) a hydrosilylation-reaction catalyst.
