Processing Instruction

At room temperature, USG661 can dry to tack-free in ~1 hour and reach a full cure after 8 hrs. The best properties, however, are typically achieved by curing at elevated temperatures.

For the package in containers, to ensure homogeneity of the material, the components must be stirred thoroughly before they are removed or processed in order to uniformly disperse any fillers that might have settled during storage.

We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to

USG661 has a shelf life of at least 6 months when stored below 30 °C in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.

Safety information
