MApplica t ion Tempera t ure We recomme nd the application roll be set at 94°F (35°C), depending on machine design and line speed
desired. No p r eheating of the adhesive o r coreactant a t the meter / mix/d i s pense un it is requ ired.

A rela tively slow initial increase in viscosity is due to the e x othermi c reaction of the adhesive immedia t ely after the mixin g process and the mechan ic al in fluences in the application system.

For short trial runs the adhesive can be batch mixed. We recommend preparatio n of no more adhesive than
can be used within 5-10 minutes. A high speed sti rrer suitable for a homogeneous mixing should be used. However, the use of a me ter/mix/dispen se device wh ich continuou sly mixes the adhesive a t the chosen
ratio

, controls the feeding of the applica t ion unit, and stops produ ction automa t ically in case of machine failures

, is ind i spensable for extended tr ials and normal production.

When processing Mor-Free L 75-173, the safety rules for working with isocyana te s must be ob served. The
adhesive con t ains monome r ic MDI. See Material Safe ty Da ta Sheet for specific de tails

.

Cleaning The applicatio n unit should be cleaned before the adh esive bec ome s insoluble by progressive curing, if the machine stop s take more than 30 minu t es.

If the app lication unit and mixing devic es are combustion proof, the y may be clea ned with ester s or ketones
such as eth y l acetate and MEK.

Several com m ercially avai lable solvents are saf e and effective for flushi ng an d cl eanin g Mor-F r ee adhe sive re si due s from sol v entless lami nators and m e ter/mix/disp ensi ng eq uip m ent that do not have
comb ustio n p r oof ratin g s. We recomme nd co ntactin g either Dynal oy , Inc. (800-669-570 9; www.dynal oy.com), o r Da n k o Indu st rie s (630 -8 82-607 0) for cl eani n g solvent re commen dation s . Always

con s ult the solvent sup p lie r’s MSDS fo r safety inform ation before u s e.

Storage Mor-Free L 75-173/C-145 can be stored in air t igh t, closed, unmixed, or iginal containers in dry rooms at temperatures of 70° ± 15 ° F

. Opened co ntainers should be used a s quickly as p o ssible. Both Mor-Free L 75-173 and C

- 145 should b e protecte d fr om freezing

.

Safety , Hand ling and Stor age

• Store in co ol, dry, well ventilated are a away fr om heat and ignition source s. Keep contai ner ti ghtly
clo s ed.

• Follow g ood manufa c turi n g and ha ndlin g pra c tice s.

• Wa sh tho r ou ghly after han dling. Wa sh contami nated goggle s , faceshi e ld, and gloves. Profe ssi onally
laund er conta m inated cl oth i ng before re -use.

• ATTENTIO N! Containe r can be ha za rd ous whe n em pty. Follow label wa rnin gs even after co ntainer is empty. Do not reu s e em pty c ontaine r without pr ofe ssi onal cleani ng.

• Refer to Mate rial Safety Da ta Sheet for more info rma t ion.
