Q1: What types of waterborne epoxy resins is KINGMIDE-X980W compatible with?
A: KINGMIDE-X980W is specifically formulated for use with standard anionic and non-ionic waterborne epoxy dispersions, including liquid and solid epoxy resin emulsions. Compatibility should be confirmed through small-scale formulation trials due to variations in resin architecture and stabilization systems.
Q2: How does X980W perform in terms of pot life and film formation at ambient conditions?
A: As a waterborne polyamide curing agent, X980W offers extended working time compared to many solvent-based alternatives—typically several hours under standard laboratory conditions (23°C, 50% RH). It supports coalescence and crosslinking without requiring forced drying, enabling good film formation and mechanical development at room temperature.
Q3: Can X980W be used in coatings requiring low VOC and high durability?
A: Yes—X980W is inherently low-VOC and enables the formulation of high-performance, waterborne epoxy coatings with excellent chemical resistance, adhesion to metal and concrete substrates, and robust physical properties after full cure.
Q4: Is pre-mixing or heating required before incorporating X980W into the epoxy dispersion?
A: No heating is necessary. X980W is supplied as a stable aqueous dispersion and can be added directly to the epoxy component under gentle agitation at ambient temperature. Avoid high-shear mixing to prevent foam generation or destabilization of either phase.
