OK-03 has advantages as economical, fast catalyzed cure, solvent-free,
excellent stability, Wide compatibility and solubility with various
kinds of resins, excellent hardness-film flexibility.
OK-03 crosslinking agent is a commercial grade of
Hexamethoxymethylmelamine(HMMM) which supplied in liquid form.
It is a versatile crosslinking agent for a wide range of polymeric
materials, both organo-soluble and water-borne.
OK-03 is soluble in most commonly used organic solvent but
solubility in water is limited-when blended with most other
water-reduciable resins, tolerates dilution in water.
The polymeric materials should contain either hydroxyl or amide
groups. The reaction of OK-03 with hydroxyl, carboxyl and amide
functionalities on other polymers is typically catalyzed with
strong acid because of its high extent of alkylation.
The polymeric materials would include alkyds, polyesters, acrylic,
epoxy, urethane, and cellulosics. OK-03 is a very effective
crosslinking agent because of its high functionality and low
tendency to self condensation.
In particular, it can provide films with high flexibility when used
