Information bearing pressure-sensitive adhesive and its sheet JP

High-viscosity vinyl polymer adhesive for carpet composition JP2001 234144
The adhesive has good water resistance and low temperature storage stability. It is a water-dilutable emulsion, a polymer dispersion colloid containing vinyl ester monomers and a polymer containing vinyl alcohol (
The dispersant has a 1,2-glycol bond ≥1.7 mol %). Example: Vinyl acetate is mixed in the presence of polyvinyl alcohol (degree of polymerization 1700, degree of saponification 98.0 mol%, content of 1,2-diols 2.2 mol%), tartaric acid, water and dibutyl phthalate. This kind of adhesive has good water resistance, adhesive strength and low temperature storage stability on plywood.

Information bearing pressure-sensitive adhesive and its sheet JP 2001 240833

The composition consists of 100 parts (solids) of a natural rubber methyl methacrylate (I) graft copolymer and 5-50 parts (solids) of an acrylate-styrene copolymer (II) emulsion. , Take 100 parts of the main material and 100-250 parts of ultra-fine particles of filler made adhesive. The adhesive is applied to the surface of the substrate and dried to form an adhesive layer. The layer is adhered to the adherend under pressure and the layer of adhesive removes the adhesive layer from the substrate when needed. This information-carrying sheet (e.g., resize paper, postcard, etc.) consists of a sheet and a pressure-sensitive adhesive layer made of the above-mentioned adhesive. Example: 100 parts of natural rubber and 10 parts of I to prepare a graft copolymer emulsion, take 100 parts of the emulsion (solid basis) and 10 parts (solid basis) I, II copolymer emulsion (Polytlon
The mixture of F2000) was mixed with 50 parts of silica gel and 125 parts of starch. The product mentioned was coated on coated paper by gravure printing and dried at 120° C. for 30 s.
The 90°C peel strength is 100-150 g.(25mm)-1, and it has good blocking resistance.

Surface Protective Film JP 2001 234141

This protective film is composed of a thermoplastic resin-based film and a peelable adhesive; the peelable adhesive is prepared using 100 parts of rubber and 1-15 parts of fatty acid-modified alkyd resin.
A coextruded film was coated with a layer of glue consisting of 100 parts hydrogenated block SBS, 2 parts Arakyd 251 and 1 part Irganox 1010. The resulting adhesive tape had an initial adhesion of 2.0 N. (25 mm)-1 on the steel plate and 4.0 N. (25 mm)-1 after one week at 70°C.

Production of self-adhesive protective film and its application on the surface of automobiles. EP 1126000 (2001-08-22)

This temporary protective film coated on the surface of a painted car consists of a carrier layer of ≥1 and a two-component (polar and non-polar) adhesive layer. The polar component (50%-99%) is an EVA polymer (vinyl acetate content 40-80%), while the non-polar component (1%-5%) is an amorphous or weakly crystalline C2-12-alpha-olefin polymer. The carrier is a thermoplastic polyolefin that is produced by co-extrusion. This protective film has the required amount of adhesive, leaving no residue after tearing.

Adhesive tape and cleaning roller JP 2001 234148

The adhesive has suitable adhesion to the adjacent release layer and it is suitable for dusting on the floor. It consists of a bottom layer, a release layer and a hot melt adhesive on the other side. The hot melt adhesive

From: (A) 100 parts of a styrene-isoprene-styrene type block copolymer (SIS) or its mixture with a styrene-isoprene type block copolymer (SI), (B A composition of 100-200 parts of extender, (C) 40-125 parts of plasticizing oil and (D) 1-7 parts of wax. A typical type of tape is: a silicone-treated PET substrate, and a hot-melt adhesive containing SIS (Quintac
3421) 74 parts, SI (Vector 411D) 26 parts, petroleum resin (Quintone N180) 170 parts, paraffin oil (Diana process oil PW90) 70 parts, paraffin wax 3 parts and Irganox 1010 1.5 parts; the initial adhesive force of the tape is 12 ball The adhesion to the release layer was 268 mN.
