COMPANY · ABOUT JCCM
Focused on reactive phosphate monomers and real formulation problems
Guangzhou Jincheng Chemical Technology focuses on the KM-series phosphate ester monomers for UV coatings, inks, adhesives, polycarboxylate superplasticisers, electronic materials and nail gels. We connect grade selection, sample testing, reference formulations and documentation around the actual substrate and failure mode.
About JCCM →Application support
Selection starts from substrate, cure route and failure mode.
Samples and formulas
Candidate grades, starting dosages and validation guidance.
Documentation
TDS, SDS, COA and regulatory documents by grade and use.
PRODUCT PLATFORM
Five grades with distinct interfacial roles
Identify the substrate, failure mode and system limits first, then select by acid value, colour, flexibility or crosslink density.
KM2110
2-Hydroxyethyl methacrylate phosphate (HEMAP)
KM2110 is the highest-acid-value monofunctional phosphate monomer in the range (265–315 mgKOH/g). It delivers the strongest adhesion to metals, …

Start from the failure, not from a grade code
Covering metal, glass, ceramics, UV coatings and inks, superplasticisers, electronics, flame retardancy, asphalt and nail gels.
UV Coatings, Inks & Adhesives
In UV systems on metal, glass and ceramics, phosphate monomers turn physical attachment into chemical bonding. Typical dosage 1–2…
Clay-Tolerant Polycarboxylate Superplasticizer
Copolymerizing KM2110 (HEMAP) into the polycarboxylate backbone replaces part of the carboxyl groups with phosphate groups, marke…
HEMA-Free Nail Gel
KM2140 is a low-acid-value (120–145), highly flexible phosphate monomer that replaces HEMA as the anchoring chemistry on the nail…
Vacuum Metallizing & NCVM
Vacuum metallized layers and plastic substrates differ enormously in thermal expansion. KM2130 in the base coat provides flexible…
Reactive Flame Retardancy
Copolymerizing phosphorus-containing monomers into the resin backbone puts phosphorus on the network instead of relying on additi…
Electronics & Battery Materials
In electrode coatings, encapsulants and structural adhesives, phosphate monomers improve adhesion to copper foil, aluminum foil, …

Answers engineers can use directly
Each article is structured around definition, mechanism, selection, testing, troubleshooting and regulatory boundaries.
Basics
What is a phosphate ester functional monomer?
A molecule with a polymerizable end and an anchoring end — the source of its “dual functionality”.
MechanismAdhesion mechanism: from adsorption to chemical bonding
Wetting and enrichment, interfacial coordination, covalent anchoring, stress buffering.
SelectionHow to choose among the five grades
Position by acid value, color, flexibility and cure chemistry.
TestingHow to test adhesion credibly
Where cross-hatch, pull-off, boiling water, salt spray and 85/85 apply — and how they mislead.

Douyin / Channels: Phosphate Functional Monomers · 63109866814
Nail gel lifts in three days? Nine times out of ten it is the base coat
Lifting usually starts at the base coat / nail plate interface; phosphate groups bond to hydroxyapatite and extend wear.
KM2140 →
Plastic parts flake on spray or wipe off? Do not change the primer yet
Phosphate esters do not work on non-polar PP/PE; a chlorinated polyolefin primer or corona treatment is required first.
Adhesion passes, then blisters in boiling water?
Boiling water tests interfacial hydrolytic stability, not initial adhesion. Choose a hydrolysis-resistant grade and control dosage.
