URAPLEZ and ULTRAPLEZ are both urethane lacquers based on the reaction between polyols and isocyanate resins.

URAPLEZ is a combination Polyol/isocyanate, modified with Cellulose Acetate Butyrate (C.A.B.).

ULTRAPLEZ is a combination Polyol/isocyanate, modified with Nitrocellulose.

SCANLAC is a combination of Alkyd/Urea Formaldehyde resins, modified with Nitrocellulose.

SOLIDS:

Both URAPLEZ and ULTRAPLEZ range in solids between 22-25% by weight.

SCANLAC is in the 25-30% solids area.

In general, SCANLAC gives excellent properties of cure response, rubbability, clarity, print and mar resistance at reasonable cost. However, recoating is a problem because of the potential for lifting between coats. Solids are reasonably high.

SCANLAC contains formaldehyde, which is currently under close scrutiny by OSHA.

URAPLEZ AND ULTRAPLEZ have the magic of the "Urethane" name going for them. They are tough, and very resistant to water spotting from drinking glasses. URAPLEZ is especially flexible and both products are less sensitive to lifting, on recoat, than SCANLAC. Their cure response is relatively slow, so that early scratch and mar resistance is only fair. Cost/Build ratio is only fair and solids are fairly low. Both materials contain lsocyanate resins, which are very moisture sensitive during storage and application and special moisture free solvents must be used.
