Q1: What are the primary application areas for ETHERAC 7303-4-X-60?
A: ETHERAC 7303-4-X-60 is widely used in high-performance waterborne industrial coatings, including metal primers, topcoats for appliances and general metal finishing, and low-VOC architectural maintenance coatings where excellent film formation, hardness development, and gloss retention are required.
Q2: Can ETHERAC 7303-4-X-60 be blended with other resin systems?
A: Yes — it exhibits good compatibility with common waterborne resins such as polyurethane dispersions (PUDs), epoxy dispersions, and certain crosslinkable acrylic emulsions. Compatibility testing under actual formulation conditions is recommended to ensure stability and performance consistency.
Q3: How should ETHERAC 7303-4-X-60 be stored and handled?
A: Store in a cool, dry place away from direct sunlight and freezing temperatures. Keep containers tightly sealed to prevent contamination and moisture loss. The product is supplied as a stable aqueous dispersion and does not require special handling beyond standard industrial hygiene practices for waterborne systems.
Q4: Does ETHERAC 7303-4-X-60 require external crosslinking agents?
A: It is designed as a self-crosslinking acrylic dispersion containing functional monomers that enable ambient or thermal cure without mandatory addition of external crosslinkers. However, co-curing with blocked isocyanates or aziridines may be employed to further enhance chemical resistance or hardness in demanding applications.
