Humiseal T73-5L Standard Solvent Based Thinner for Humiseal Coatings
HumiSeal T73-5L — Standard Solvent-Based Thinner for HumiSeal Conformal Coatings, 5L Can
HumiSeal T73-5L (SKU: T73-5L) is a standard solvent-based thinner formulated for use with compatible HumiSeal conformal coatings. Based on butyl acetate, T73-5L is used to lower coating viscosity as received from the factory or to restore viscosity during processing when solvent evaporation has thickened the coating bath. Supplied in a 5L can. RoHS compliant.

Frequently Asked Questions
Which HumiSeal coatings is T73-5L compatible with?
T73-5L is HumiSeal's standard solvent-based thinner and is compatible with a range of HumiSeal solvent-based conformal coatings. Always verify compatibility with your specific HumiSeal coating product by checking the coating's TDS or contacting HumiSeal/MTE Solutions before use, as some coatings require a specific thinner formulation.
How much T73-5L should I add to my coating?
The amount of thinner required depends on the current viscosity of your coating and your target application viscosity. HumiSeal recommends measuring viscosity with a calibrated viscometer and adding thinner incrementally, mixing thoroughly between additions. Refer to your specific coating's TDS for recommended viscosity ranges by application method (spray, dip, selective).
Can T73-5L be used with water-based HumiSeal coatings?
No — T73-5L is a solvent-based thinner (butyl acetate) and is not compatible with water-based conformal coatings. Water-based HumiSeal coatings require a water-based thinner. Check your coating's TDS to confirm the correct thinner before use.
What is the flash point of T73-5L and what precautions are needed?
T73-5L has a flash point of 27.2°C, classifying it as a flammable liquid. Store away from heat sources and open flames. Use in a well-ventilated area or with appropriate fume extraction. Refer to the HumiSeal SDS for full handling, storage, and PPE requirements.
Is T73-5L RoHS compliant?
Yes — T73-5L complies with RoHS Directive 2002/95/EC, making it suitable for use in electronics manufacturing environments with RoHS compliance requirements.
