alkyd resin

polymer

Alkyd resin is a synthetic polyester formed by the condensation of polyols (typically glycerol) with fatty acids and dibasic acids, creating a cross-linked polymer network widely used in protective coatings and adhesives. The material is valued in industrial applications for its excellent adhesion, hardness development, and compatibility with pigments and solvents, making it a cost-effective choice for wood finishes, metal primers, and architectural paints where durability and ease of application are priorities. Alkyds remain competitive against acrylics and polyurethanes in environments where moderate moisture resistance and weathering performance are acceptable, though they typically cure more slowly than some alternatives.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
