Why it matters

Some cores cannot meet water. Effervescent products, strongly hygroscopic actives and several of the enteric polymers behave far better out of a solvent system, and the metallic and pearl finishes depend on it. Solvent processing brings its own requirements, a recovery system, a flameproof area and residual solvent testing, and those are yours to hold rather than ours.

The solvent range is the larger of the two because moisture sensitive work lives here. All four moisture barrier grades are solvent based: CVS-101 for Amoxycillin with Clavulanate, PA-Wt10 for plain Amoxycillin, MB 31RP for multivitamin and ferrous cores and AC-8 for special category tablets. So are four of the five enteric grades and the MNaq metallic and pearl series. NaQ-Z1Wb and NaQ-Z1Wt10 are the solvent equivalents of the aqueous film coats, and SFC101 is the sugar film coat.

Running it

Solvent systems build faster and run cooler than their aqueous equivalents. Watch the spray rate rather than the temperature, because over-wetting shows up as picking long before the bed reads hot.

Grades in this category

Every grade is listed with what it is for, the process base it runs on and the actives it was formulated against, so the choice between two of them can be made here rather than on a sample.

  • Non-aqueous film coat, white or colour

    Solvent base ready-mix film coat for moisture sensitive cores.

    Solvent base film coating for cores that cannot tolerate an aqueous process. It is supplied white or in your agreed shade, with the same finish characteristics as the aqueous grade at a lower bed temperature.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    White or colour, high gloss

  • Non-aqueous film coat, extra white

    Solvent base extra white film coat for high opacity cover on sensitive cores.

    Non-aqueous extra white film coat for moisture sensitive tablets that also need high opacity. It combines a solvent process with the covering power of the Wt10 series.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Extra white, high opacity

  • Universal film coat

    One grade that runs on either an aqueous or a solvent process.

    Universal film coat material for units that run mixed processes and want to hold a single grade in stores. It can be dispersed in water or in solvent, so the same code covers both product lines.

    Base ·
    Aqueous or non-aqueous
    Finish ·
    White or colour

  • Sugar film coat material

    Non-aqueous sucrose based system for a sugar coated finish without a full sugar line.

    Non-aqueous sugar film coat that covers the tablet with a sucrose based solution and provides protection from light and moisture. It is fully formulated on HPMC, so a conventional or auto coater delivers the sugar coated appearance without the traditional multi stage sugar coating process.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Sugar coated appearance

  • Enteric coat, methacrylic base, non-aqueous

    Solvent base methacrylic enteric film for the Pantoprazole group.

    Methacrylic base enteric coating applied from a non-aqueous system, formulated for the Pantoprazole group and other dissolution critical enteric tablets. It runs best over a transparent seal coat such as SC-401, which protects the acid labile core.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Enteric film, gastro resistant
    Formulated against ·
    Pantoprazole group

  • Enteric coat, phthalate base

    Phthalate base enteric system for Duloxetine enteric tablets.

    Phthalate base enteric coating material formulated for Duloxetine enteric tablets, where the release profile is governed by the phthalate polymer rather than a methacrylic film.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Enteric film, gastro resistant
    Formulated against ·
    Duloxetine

  • Enteric coat, methacrylic second bond

    Second bond methacrylic enteric system for Mesalamine.

    Methacrylic base enteric coating on a second bond, formulated for Mesalamine enteric tablets where release has to be held until a defined point in the intestinal tract.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Enteric film, delayed release
    Formulated against ·
    Mesalamine

  • Enteric coat, CAP base

    Cellulose acetate phthalate enteric film for Diclofenac and Serratiopeptidase.

    CAP base enteric coating material for Diclofenac and Serratiopeptidase enteric tablets. It is the alternative polymer route to ECM-RP348 where a CAP film is specified.

    Non-aqueous (solvent)
    Finish ·
    Enteric film, gastro resistant
    Formulated against ·
    Diclofenac, Serratiopeptidase

  • Transparent seal coat and pre-coat

    Clear sub-coat laid down before an enteric layer on acid labile cores.

    Transparent layer seal coat or pre-coat applied ahead of an enteric coat, specified for the Pantoprazole group. It isolates the core from the enteric polymer and gives the functional layer a uniform surface to build on.

    Base ·
    Aqueous or non-aqueous
    Finish ·
    Transparent
    Formulated against ·
    Pantoprazole group

  • Colour or white seal coat

    Pigmented sub-coat where the seal layer also has to cover the core.

    Colour or white seal coat for cores that need covering as well as sealing, so the finishing film coat can be applied at a lower build-up.

    Base ·
    Aqueous or non-aqueous
    Finish ·
    White or colour

  • Moisture barrier for Amoxycillin and Clavulanate

    Solvent base extra white barrier film for the most moisture sensitive combination.

    Moisture barrier film coat on a solvent base, extra white, developed for Amoxycillin and Clavulanate potassium tablets. Water ingress during and after coating drives degradation in that combination, and this grade is built to hold it out.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Extra white, moisture barrier
    Formulated against ·
    Amoxycillin and Clavulanate potassium

  • Extra white film coat for plain Amoxycillin

    Solvent base extra white film for plain Amoxycillin and dissolution critical tablets.

    Solvent base extra white film coat for plain Amoxycillin tablets and other products where dissolution has to be protected while the core is covered to a high opacity.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Extra white
    Formulated against ·
    Amoxycillin

  • Moisture barrier for multivitamin and ferrous tablets

    Solvent base barrier film for hygroscopic multivitamin and iron formulations.

    Solvent base moisture barrier film coat for Multivitamin and Ferrous group tablets. It protects the core from moisture pick-up and from the colour change that follows it on shelf.

    Base ·
    Non-aqueous (solvent)
    Finish ·
    Colour or white, moisture barrier
    Formulated against ·
    Multivitamins, Ferrous group

  • Moisture barrier for special category tablets

    Solvent base barrier film for products outside the standard range.

    Moisture barrier film coat on a solvent base for special category tablets whose stability profile is not covered by the CVS, PA or MB grades. It is formulated against the specific core on request.

    Base ·
    Non-aqueous (solvent)

  • Metallic and pearl film coat

    Solvent base metallic and pearl effect film coats, supplied in the agreed shade.

    The MNaq series is a non-aqueous ready-mix film coat that gives a metallic or pearl effect finish. Each shade carries its own code, and every code runs the same way on the coater. The shade is matched and confirmed against your reference sample before the batch is released, so a repeat order reproduces the finish you approved rather than a fresh interpretation of it.

    Non-aqueous (solvent)
    Finish ·
    Metallic or pearl, shade on reference
