Is a “Texanol Type” coalescent the same as genuine Eastman Texanol?

Not necessarily. Texanol is an Eastman trademark. A material from another origin should be identified by its chemical name or CAS 25265-77-4 and its own specification; performance comparability must not be represented as branded origin.

Is TMPD-MIB CAS 25265-77-4 a single ester isomer?

Commercial TMPD-MIB is commonly an isomer mixture of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate rather than a single defined ester isomer. Compare the stated composition and analytical specification rather than treating the CAS number as a complete composition description.

Which details should be compared for a TMPD-MIB coalescent in waterborne coatings?

Confirm identity, ester-alcohol assay, colour, water, acidity and the agreed analytical methods. Evaluate the offered product in the intended binder system for film formation and appearance, because a COA alone does not establish equivalent coating performance.

TMPD-MIB Coalescent (Texanol Type) CAS 25265-77-4

TMPD-MIB Coalescent (Texanol Type, CAS 25265-77-4, EC 246-771-9) is an ester-alcohol coalescent used as a film-forming aid in waterborne coatings. Commercial material may contain positional monoisobutyrate isomers, so identity, ester-alcohol assay, isomer profile, water, acidity, color and application performance should be compared. Texanol is an Eastman trademark; “Texanol Type” is only a performance reference unless genuine branded origin is documented. Confirm the offered specification, packaging and SDS before trial or purchase.

Product Overview

TMPD-MIB (CAS 25265-77-4, EC 246-771-9) is a multi-constituent mixture of monoisobutyrate positional isomers used as a coalescent and film-forming aid in waterborne coatings. Texanol is an Eastman trademark. A material from another origin should be identified as TMPD-MIB coalescent or Texanol type and assessed against its own specification. Confirm identity, ester-alcohol assay, isomer profile, water, acidity, color and packaging; do not transfer branded performance or compliance claims to another material.
