Q1: What is the primary application field for Sam Chung 1170F Alkyd Resin?
A: Sam Chung 1170F is a medium-oil-length alkyd resin designed primarily for solvent-based decorative and protective coatings, including industrial maintenance paints, general-purpose enamels, and wood finishes where good gloss retention, through-dry performance, and substrate adhesion are required.
Q2: Is Sam Chung 1170F compatible with common crosslinkers and co-resins?
A: Yes — it exhibits good compatibility with melamine-formaldehyde resins, urea-formaldehyde resins, and isocyanate-based hardeners in baked or ambient-cure systems. It also blends well with other alkyds, acrylics, and cellulose derivatives to modify film properties such as flexibility, hardness, and drying speed.
Q3: How should Sam Chung 1170F be stored to maintain stability and performance?
A: Store in tightly sealed containers in a cool, dry, and well-ventilated area away from direct sunlight and sources of heat or ignition. Under these conditions, shelf life is typically 12 months from date of manufacture. Avoid prolonged exposure to moisture or freezing temperatures.
Q4: Does Sam Chung 1170F contain heavy metals or restricted substances?
A: Sam Chung 1170F is formulated without intentionally added lead, cadmium, mercury, or hexavalent chromium. It complies with major global regulatory frameworks concerning heavy metal content in industrial coating resins, though final compliance depends on the full formulation and end-use application.
