IRS 2040-1 Epoxy Potting Compound, Flame Retardant Encapsulating Compound

From £23.10 (£27.72 inc. VAT)

IRS 2040-1 Epoxy Potting Compound is a non-toxic general purpose flame retardant encapsulating compound. It has a long pot life and can be cured at ambient temperatures or accelerated with heat. When cured, IRS 2040-1 exhibits good surface finish, high electrical strength, good thermal conductivity, low exotherm and low cure shrinkage. It is compatible with most PCB components and materials over a wide range of temperatures. In addition to this it has excellent adhesion to most plastic and metal substrates. IRS 2040-1 is suitable for a wide variety of applications due to its combination of properties and ease of use. It does not contain halogens or heavy metals and comes in a standard colour of black.
