ISO 277 is the international standard for raw tung oil in binders for paints and varnishes. The aim of ISO 277 is to ensure that the product conforms to the technical specification.
It specifies the requirements and the corresponding methods of testing for two types of raw tung oil suitable for paints and varnishes.
Note 1: ISO 277 is not intended to apply to tung oils that are wholly or partly solidified as a result of polymerization.
ISO 277 on raw tung oil in binders for paints and varnishes is useful for:
Tung oil is often used by paint and varnish manufacturers as a generic name for any wood-finishing product. Since tung oil has become popular as an environmentally friendly wood finish, some products labelled as "tung oil" are actually blends containing other oils, varnishes, solvents, or chemical driers, and may even contain no tung oil at all.
ISO 277 provides a test procedure to determine if your product complies with the requirements of the technical specification for raw tung oil in order to maintain the quality of the product.
It helps the suppliers to ensure that the performances declared by different manufacturers for a certain characteristic are reliable and truly comparable.
