Full Description

Neopentyl glycol diglycidyl ether (CAS 17557-23-2), an aliphatic difunctional epoxy reactive diluent and modifier for epoxy resin systems. It lowers formulation viscosity and is used as a coating and sealant additive.

Frequently Asked Questions

What is diglycidyl ether used for?

Neopentyl glycol diglycidyl ether (CAS 17557-23-2) is an aliphatic difunctional epoxy reactive diluent used to lower the viscosity of epoxy resin systems while remaining reactive into the cured network. It also serves as a coating and sealant additive. RawSource supplies it in bulk to resin and coatings formulators.

What is neopentyl glycol diglycidyl ether used for?

It is used as a reactive diluent and modifier in epoxy formulations — reducing formulation viscosity for easier handling and as a viscosity-modifying additive in coatings and epoxy sealant systems. It is incorporated by the formulator at levels set for the target rheology and cure.

How is neopentyl glycol diglycidyl ether different from butanediol or trimethylolpropane glycidyl ethers?

All are epoxy reactive diluents but differ in backbone and functionality: this product is the difunctional neopentyl glycol diglycidyl ether, 1,4-butanediol diglycidyl ether is a linear difunctional diluent, and trimethylolpropane triglycidyl ether is trifunctional for higher crosslink density. Choose by required viscosity reduction and functionality; confirm by CAS.

What is the HS code for neopentyl glycol diglycidyl ether?

It classifies under HS 2910.90 — epoxides and epoxyethers with a three-membered ring, other. Verify the destination tariff line with your customs broker; RawSource provides commercial documentation with each bulk shipment.

What is the cost of bulk neopentyl glycol diglycidyl ether?

Bulk pricing depends on grade, packaging, and order volume. Request a quote from RawSource with your target quantity (drums or totes) for current pricing, CoA, and SDS.
