Nonwovens made from the raw material melamine resins, using a meltblown process, are able for the first time to combine the outstanding properties of the raw material with the benefits of a meltblown.
The control laminate was made with an overlay paper (OL) containing melamine resin at a 65 Pwt% and an enzyme concentration of 0.5% based on TRS of the polymer fraction.
Therefore, the relatively constant distribution of residual methoxy groups suggests the observed melamine-enrichment zones are not simply developed by inhomogeneous mixing of the polyester and melamine resins. The melamine molecules must be crosslinked via self-condensation that results in localized melamine enrichment.
This paper was composed of 100 percent northern or western bleached sulfate with 3 percent of melamine resin for wet strength and 3 percent of titanium dioxide pigment for opacity.
The research screening process involved many variables, but resulted in a resin binder based on melamine resin chemistry.
In the 18,650-square-foot melamine resin saturation area, paper is dipped twice in the Babcock saturator, run through metering rollers, then sent to a smoothing bay.
Water-based releases for PUR, rubbers, composites molded with polyester, epoxy, vinyl ester, phenolic and melamine resin systems.
has obtained a patent for a method for imparting defoaming property to a baking finish type topcoat paint containing an acid anhydride curing agent, a melamine resin curing agent or a glycidyl-containing acrylic resin/acid anhydride curing agent for motor vehicles comprised of the step of adding a copolymer of 2%-50% by weight of a polymerizable monomer capable of forming a copolymer having isocyanate groups which can react with a binder resin in thermosetting paint or a polymerizable monomer capable of forming a copolymer having groups capable of producing isocyanate groups which can react with a binder resin in thermosetting paint during baking step of the same paint, and 98%-50% by weight other monomer or polymer reactable with the polymerizable monomer or to the topcoat paint.
Now they are being developed for structural, extruded WPC applications, which would benefit from the melamine resin's high affinity for and adhesion with the wood filler.
BASF reports that its Basotect melamine resin foam is being used in aircraft seat cushions, making them much lighter than conventional ones.
