摘要:
This charge-transporting varnish includes: a fluorine-containing charge-transporting substance; a non-fluorine-containing charge-transporting substance; a dopant substance comprising a heteropoly acid; and an organic solvent. The fluorine-containing charge-transporting substance is a polymer which has a weight average molecular weight of 500-200,000, and which is obtained by condensing: at least one compound selected from triarylamine compounds and tetraarylbenzidine compounds; a tetraarylbenzidine compound having at least one aryl group substituted with an alkoxy group which may include ether bonds; a fluorine-containing aryl aldehyde compound; and a fluorene derivative having a carbonyl group. The non-fluorine-containing charge-transporting substance is an oligoaniline compound. The charge-transporting varnish provides a thin film with which an organic electroluminescent element exhibiting excellent luminance characteristics can be achieved, even in cases when employed as a single layer in a state of being provided between and in contact with a positive electrode and a light-emission layer.

A piston coating is described that comprises a phenolic resin, at least one solid lubricant selected from among the group including graphite, MoS 2 , WS 2 , BN, and PTFE, as well as carbon fibers. Said coating has an advantageous wear resistance and an advantageous coefficient of friction.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung von Lackoberflächen mit einem hohen Glanzgrad und geringer Verschmutzungsneigung auf Gegenständen. Erfindungsgemäß werden den Decklacken vor deren Auftrag auf die Gegenstände und Aushärtung geringe Mengen an Silanen zugegeben. Die Lackoberflächen können sowohl auf Holzwerkstoffplatten als auch auf Gegenständen aus Metall, Glas, Keramik u. ä. aufgebracht werden.
摘要:
The invention relates to a substrate comprising a layer of crystalline triazine with a protective compound having a retention of oxygen barrier at 85% RH of about 50% or better. The protective compound preferably contains an azine-formaldehyde or phenol-formaldehyde resin, preferably with an hydroxy-functional polymer, and is cured.
摘要:
A process for the manufacturing of a decorative laminate having a base layer, a decorative layer and a wear layer wherein a decor is printed on a base layer. The decor printed comprises a printing ink and the wear layer comprises a thermosetting resin selected from the group consisting of; melamine-formaldehyde resin, phenol-formaldehyde resin, urea formaldehyde resin and mixtures thereof. An amount of amino resin is mixed into the printing ink in order to increase the bond between the decorative layer and the wear layer. The layers are laminated together in a laminate press under increased temperature and pressure.
摘要:
An aqueous metal surface treatment composition comprising the following ingredients : (A) an aqueous dispersion of a phenolic resin that includes a reaction product of (i) a phenolic resin precursor; (ii) a modifying agent, comprising a hydrocarbyl moiety bonded to at least one functional moiety that enables the modifying agent to react with the phenolic resin precursor; and at least one ionic moiety comprising an ionizable sulfur or phosphorous group; and (iii) at least one multi-hydroxyphenolic compound; and (B) optionally an acid where (iii) in (A) is optional where the reaction product contains two or more reactive phenolic methylol groups.
