BUILDIN G MATE RIALSAdcote 503A can react or i n teract with o t her component s of lamina t ions. Retained solvents, slip additives, antiblock age nts, and con t aminated solvents are some of the comp onents tha t may cause property change s of the film and /or adhesive

.

High mol e cul a r wei ght pol yesters that a r e used in sol u tion adh esiv es like Adcot e 503A have tenden cy to

form a revers ible s t ruc t ure in s o lution wit h time. This stru cturi ng is accele rated whe n the adh esive is exposed to temperature s b e low 5 0 °F. The stru ctu r ing is reversibl e if heat and sh ear is a pplie d to the

adhe sive. We recomme nd placin g the containe r of ad hesive in a steam ca binet, allowin g venting of the

contai ner a n d heating to 11 0-14 0°F. After the adh esi v e reache s the prop er tem peratu r e, mix the

adhe sive in the co ntaine r for 1-3 hou rs unde r mod e rate she a r. Use of a disperser o r “Co w le s” type blad e
will sh orten th e time neede d.

Cau t ion must be taken because o f th e flammabilit y of the solv e n ts used in the adhesiv e . Please

rev i e w MSDS for hazard s associa t ed w i th the ad h esiv e

.

Attempting to redispe r se without heat may redu ce the apparent visco s ity, but not result in a homog ene ou s mix. Before using the a d hesive, che c k, to make su re that all resi n has returne d to a true

solutio n and no gel s rem a i n
