摘要:
Papermaking felts include a base material and a batt layer provided on one or both sides of the base material. The batt layer includes a water-absorbing resin, and the water-absorbing resin has a coefficient of water absorption of from 1.05 and 10.
摘要:
A paper transporting felt includes a base layer, a first batt layer formed on a wet paper side surface of the base layer, a second batt layer formed on a roll side surface or a shoe side surface of the base layer, and a wet paper contacting fibrous layer formed on a wet paper side surface of the first batt layer so as to come into direct contact with a wet paper. The wet paper contacting fibrous layer is made of modified cross-section fibers.
摘要:
There is provided a composition for functioning as an effective additive for an epoxy resin that is a solid at room temperature and has a high storage stability, and a method thereof. The composition of the present invention is a basic silane coupling agent organic carboxylate composition obtained by first synthesizing an organic carboxylate of a basic silane coupling agent by reacting a basic silane coupling agent and an organic carboxylic acid, and subsequently heating and mixing the organic carboxylate of the basic silane coupling agent with a compound exhibiting a good affinity for the basic silane coupling agent or organic carboxylic acid and having a softening point or melting point of 40° C. or greater.
摘要:
A water-based metal surface treatment agent for the surface treatment of metals including aluminum products such as pre-coated aluminum sheets gives excellent coating film adhesion, flexibility and acid resistance.The water-based metal surface treatment agent contains the following components (1) to (3): (1) A copolymer, containing in a side chain, a diketene or ketoester capable of switching between keto and enol tautomeric forms, and containing at least one hydrophilic side chain containing a cationic group, an anionic group, or a nonionic group; (2) An epoxy resin modified with a phosphoric acid type compound; and (3) A water-soluble curing agent.
