EP21LP Gray Product Information

Master Bond EP21LP Gray is a two component, room temperature curing epoxy adhesive, sealant, coating, and encapsulating system featuring outstanding physical properties, superb dimensional stability and low shrinkage upon curing. This moderate viscosity system has a very forgiving 1 to 1 mix ratio by weight or volume. In fact, EP21LP Gray has the unusual feature of allowing the properties of the cured system to be altered by tweaking the mix ratio. Adding more Part A (maximum allowed 2:1 mix ratio by weight) will give a more rigid cure, which allows for better machinability. Adding more Part B (maximum 1:2 mix ratio by weight) offers a more forgiving cure, allowing for enhanced impact and shock resistance. It bonds well to a variety of substrates including metals, composites, glass, ceramics and many rubbers and plastics. EP21LP Gray features solid thermal cycling resistance. It also withstands many chemicals including water, oils, fuels and many acids and bases. It is serviceable over the wide temperature range of -60°F to +250°F. The color of Part A is gray and Part B is amber. Once cured , EP21LP Gray is a highly reliable electrical insulator. EP21LP Gray is truly a versatile system and can be used in electronic, electrical, aerospace, optical and OEM applications, among others.
