A standard sample request is normally expedited within 72 business hours upon receipt. Our standard sample size is 16 oz. (1 pint) and will be sent free of charge in the continental USA and Canada. Larger sample sizes are available and may be provided at a nominal cost. Samples requested that are currently not in inventory will be backordered and shipped immediately upon availability. All samples will include a technical bulletin, MSDS sheet and packing slip.
