	• Emission control catalysts
	• Catalyst recycling services
	• Silicate for catalyst manufacturing
Packaging & engineered plastics	• Catalysts for high-density polyethlene and chemicals syntheses
	• Antiblocks for film packaging
	• Solid and hollow microspheres for composite plastics
	• Sulfur derivatives for nylon production
Highway safety & construction	• Reflective markings for roadways and airports
	• Silica gels for surface coatings
Consumer products	• Silica gels for edible oil and beer clarification

Contract Assets and Liabilities

A contract asset is a right to consideration in exchange for goods that the Company has transferred to a customer when that right is conditional on something other than the passage of time. A contract liability exists when the Company receives consideration in advance of performance obligations. The Company has no contract assets on its condensed consolidated balance sheets as of June 30, 2020 and December 31, 2019.

The Company recognized a $9,000 contract liability associated with the sale of a portion of its sulfate salts product line in June 2019, of which $4,140 and $6,450 of deferred revenue remained as of June 30, 2020 and December 31, 2019, respectively. The Company recognized revenue of $1,035 and $2,304 related to this contract liability during the three and six months ended June 30, 2020. The Company did not recognize revenue related to this contract liability during the three and six months ended June 30, 2019. Refer to Note 7 of these condensed consolidated financial statements for additional information related to the sale of the product line.
