Смола MC39, эквивалентная смоле DOW'S VMCC и VMCA / WACKER'S LL4320 / E15 / 45M
Виниловая смола MC39 является смолой со средним молекулярным весом, карбокси-функциональным терполимером, состоящим из винилхлорида, винилацетата и малеиновой кислоты. Поставляется в виде порошка.
Смола обладает высокой выносливостью к ароматическим растворителям. resin has a high tolerance for aromatic diluents. Она сшиваема с эпоксидной виниловой смолой. Абладает хорошой адгезивностью к винилу, металлам, бетону и целлюлозным основам. with epoxy vinyl resin. It has good adhesion to vinyl, metals, concrete and cellulosic substrates. Из-за низкого молекулярного веса смола обеспечивает раствор низкой вязкостью и высоким содержанием твердых частиц.

Recommendation for Resin Dissolving Procedure:
Add weak solvent such as ethyl acetate or toluene into the blending tank first with agitation.
Slowly put terpolymer resin such as UMCH or UMOH into the above solvents with agitation.
Put strong solvents last, such as MEK or MIPK
If possible, heating and keeping temperature at 60-70 degree C, which will help the dissolving process, otherwise, takes longer time.
Resin concentration may vary with client’s formulation
Features:
This terpolymer contains carboxyl group, therefore, it features good adhesions to aluminum foil, also because it contains PVC so, also has good resistance to alkali, base, brine, salty mist, also has good resistance to oil ester and alcohols.
Packing and Storage:
25 Kg /Bag; Craft Paper Bag or PP Knitted Bag lined with plastic film.
Resin has a shelf life of approximately twenty four months when stored at 24(75H) and low humidity. Storage at higher temperatures or conditions of high humidity may result in some product discoloration.
Stored in dry place at room temperature, Safety Issue refer MSDS and SGS Report
