Paper impregnation acrylic

Some previous work is shown in Table I R. D. Smith (2) impregnated the paper in a book with acrylic resin and ethyl hydroxyl-ethyl cellulose solutions to increase fold. Salz and Skrivanek (2) patented solutions of polyvinyl butyral and formal for the purpose these materials have been supplied under the name of Regnal. Baer, Indictor, and Joel (3) compared the folding endurance of papers impregnated with Regnal,... 

Latex copolymers including NIBA have found applications in protective coatings, binders for nonwoven fabrics, water and oil repellancy, crease resistance, print pastes, leather finishing, adhesives, paper impregnation, curable thickeners and elastomers.

A number of higher poly(vinyl ether)s, in particular the ethyl and butyl polymers, have found use as adhesives. When antioxidants are incorporated, pressure-sensitive adhesive tapes from poly(vinyl ethyl ether) are said to have twice the shelf life of similar tapes from natural rubber. Copolymers of vinyl isobutyl ether with methyl acrylate and ethyl acrylate (Acronal series) and with vinyl chloride have been commercially marketed. The first two products have been used as adhesives and impregnating agents for textile, paper and leather whilst the latter (Vinoflex MP 400) has found use in surface coatings.

This technique may be used for textile webs, non-woven web, paper or foils. The non-woven webs or foams may be impregnated by binders, such as acrylic dispersion binders, but the coating weight must be controlled by squeezing out the excess adhesive or binder. 

Plastic parts containing glass or mineral fibre reinforcements generally cannot be sectioned using a microtome because the fibres tend to break or fall out of the sectioned sample. Such samples must be embedded in epoxy, polyester or acrylic, and polished using silicon carbide papers and diamond impregnated cloths. If morphology is more important than... 

Pre-impregnated foils are used where the surface requirements for resistance and closedness do not require more expensive high-density laminates. The impregnation will be made on the paper machine, using a modified size press. Typical resins for this application are UF (urea formaldehyde) or MF (melamine formaldehyde) resins vdth a very low content of free formaldehyde. To achieve good flexibility and printability of these foils, additional polymer dispersions (e. g. styrene acrylates) are used. 

Solvent bonding is suitable for all amorphous plastics. It is used primarily on ABS, acrylics, cellulosics, polycarbonates, polystyrene, polyphenylene oxide, and vinyls. Solvent welding is not suitable for crystalline thermoplastics. It is not effective on polyolefins, fluorocarbons, or other solvent-resistant polymers. Solvent welding is moderately effective on nylon and acetal polymers. Solvent welding cannot be used to bond thermosets. It can be used to bond soluble plastics to unlike porous surfaces, including wood and paper, through impregnation and encapsulation of the fibrous surface.
