| Uses | This product is often used as an intermediate in many production, such as the corrosion inhibitor tolyltriazole, rubber additive MMB. It can be used as the starting agent of special hard foam polyether. The polyether polyol synthesized with OTD as the starting agent can make the foam uniform without causing shrinkage, which improves the thermal insulation performance and low temperature dimension performance of the foam. Another type of hard foam polyether is soluble in cyclopentane. It is an alternative to the more expensive o-phenylenediamine in a lot of applications, including epoxy resin curing, polymer initiation, cross-linking, chain extension and end closure. |
