melamine — formaldehyde (MF) resins [3909 20]
The present invention relates to a melamine/formaldehyde (MF) resin composition containing a condensed tannin, and to the use thereof.
Melamine formaldehyde is also called melamine resin, cymel 481 resin, melamine and melamine formaldehyde polymer.
Melamine formaldehyde is also called melamine resin, cymel 481 resin, melamine and melamine formaldehyde polymer.
Aminoplasts is also known as melamine resin, melamine formaldehyde.
Also known as melamine formaldehyde resin, melamine resin.
The adhesive resin is preferably an epoxy resin, a melamine resin, a polyimide resin, a polycarbonate resin, a phenolic resin, or a fluorosilicone resin.
The thermosetting resin may include phenol formaldehyde, urea formaldehyde, melamine formaldehyde, melamine urea formaldehyde, or methylenediphenyl diisocynanate.
The method includes mixing of cured melamine formaldehyde resin and partially cured melamine formaldehyde resin.
The first amino-formaldehyde resin may be a melamine-urea-formaldehyde resin.
The polymeric coating includes the reaction product of an acrylate copolymer comprising styrene units and having a hydroxyl number of from 20 to 500 mg KOH/g or an acid value of from 20 to 500 mg KOH/g, and an epoxy and/or a melamine.
The melamine formaldehyde molding composition includes between approximately 15% and 50% by weight of cured melamine formaldehyde resin and between 85% and 50% respectively by weight of partially cured melamine formaldehyde resin.
The thermoset matrix can be, for instance, a phenol-formaldehyde resin, a melamine-formaldehyde resin, or a polyester resin.
The polymer network has free groups which are reactive towards reactive melamine-resin and epoxy-resin pre-condensates.
Amino resin can be melamine-formaldehyde resin or urea- formaldehyde resin or their mixture and mixed with a softener.
The resin can be mixed with full etherfied melamine amino resin or high imino melamine amino resin to obtain water-soluble amino roasting-type varnish and colored paint.
Each layer contains at least cured melamine-formaldehyde resin or consists thereof.
The invention is directed to an adhesive system for wood containing a synergistic mixture of melamine-formaldehyde resin, phenol-formaldehyde resin, and cross-linked polyvinyl acetate emulsion resin wherein the mixture is cured by an acid.
A melamine-urea-formaldehyde resin modified with a cyclic urea prepolymer and sodium metabisulfite.
The protective agent can be phenol formaldehyde resin, melamine formaldehyde resin or urea formaldehyde resin, which is applied on the wood as an aqueous solution and dried by means of heat.
The invention relates to a process for preparing a liquid melamine urea formaldehyde resin that has long term stability.
The invention relates to a kit comprising a sponge that consists of a melamine-formaldehyde resin and an aqueous detergent for hard surfaces.
