VMCH Resin
SKU: RXSOL-18-1823-025
VMCH resin is a high molecular weight, carboxyl-functional terpolymer comp rised of vinyl chloride, vinyl acetate and maleic acid. It is supplied as a powder. VMCH resin provides good adhesion to vinyl, metals, and concrete and celllulosic substrates. This resin gives highly flexible, post-formable coatings on metal coil and sheet.
Application
VMCH is mainly used for air-dry finishing paint, for example, repair paint, vessel paint, metal / can / beer paint, wood & glass coating, aluminum foil varnish, etc. It also can be used for making ink, adhesive (metal with metal, metal with PVC/PET), heat-seal packing paint (medicine packing, cigarette packing), glue for vitamine C packing, etc. It is complying with the standard of food & medical contact.
Dosage
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 VMCH or UMOH into the above solvents with agitation.
Put strong solventslast, 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'sformulation
