- Properties and Fields of use
In combination with isocyanate pre-polymers, such as Desmodur L, IL, HL, N, VL, for air-drying
two-component polyurethane coatings. Synthoester 1130 is especially suitable for fast drying
polyurethane coatings in combination with Desmodur IL or HL.
The low OH-content makes relatively long pot lives of mixtures possible, providing very good
application possibilities with casting machines.- Processing information
As with all polyurethane coatings, solvents containing hydroxyl groups should not be used.
Suitable solvents are ketones, esters and most aromatic solvents. Solubility and compatiblility
with reaction partners are as follows:
Solvents Di- and polyisocyanate
Ethyl acetate + Desmodur N +
Butyl acetate 98/100 + Desmodur L +
Methyl glycol acetate + Desmodur HL +
Ethyl glycol acetat + Desmodur IL +
Acetone + Desmodur VL +
MEK +
MIBK +
Toluene 0 to 15% non-vol. comp.
Xylene 0 to 30% non-vol. comp.
Hydroxyl polyesters
Synthoester 1120 0 to 1:1
Synthoester 1018 +
Synthoester 1080 +
Synthoester 1110 0 to 1:1

Technical Details & Test Data
- Mixing ratio with poly-isocyanates
100 parts by wt of Synthoester 1130/75% (form in which supplied) are equivalten of the
following amounts of Desmodur:
Desmodur HL 60 70 parts by wt.
Desmodur IL 50 92 parts by wt.
Desmodur L 67 64 parts by wt.
Desmodur L 75 57 parts by wt.
Desmodur N 45 parts by wt.
Desmodur VL 25 parts by wt.
The amount of Desmodur added may deviate by +/- 20% from the equivalent amount. For
primers and intermediates coats, undercuring, and for topcoats exposed to unusual conditions,
overcuring is recommended.
