informa t ion

. Adcote 3220 resin can react or in teract with o t her c o mponents o f the s t ructure

. Re tained

solvents

, slip additives, an tiblock agents and contamin at ed solven ts are some of the compone nts tha t may

cause property changes o f the subs trates and/or Adcote 3220 resin

.

General Info r m ation

The initia l color and clarity of Adcote 3 2 2 0 resin will re main unchan ged after ou td oor exposure. In addition,

Adcote 3220 resin is resist ant to attack by dilu te ac id and alkali solutions. When mixed with c o reactant, the

tensile s t rength and resista n ce to chemical plasticize r s , solven ts a nd water are noticeably improved. The

melting tem p erature range will also incr ease. With some substrates, the addi tion of a core actant ma y

improve adhe sion.

High mole cul a r weig ht po lyester adh e s ives like Ad cote 322 0 h a ve a te nde ncy to fo rm a reversibl e

stru cture in solutio n with time. This stru ctur i ng i s a c cele rate d wh en the adhe sive i s exposed t o

temperature s belo w 5 0 °F. The structu r i ng i s reversib le if heat and she a r are ap plied to th e a dhe sive. We

recomme nd placi ng the containe r of adhe sive in a st eam cabin e t, allowing ve nting of the containe r and

heating to 1 10-1 40° F. After the adhe sive rea c h e s the prope r tempe r ature, mix the adhesive in the

contai ner for 1-3 ho urs un der mo derate shea r. Use of a dispe r ser or “Co w le s” type blade will shorte n the

time neede d.

Cau t ion must be taken b ecause of th e flammabilit y of the solv ents used in the ad hesi v e . Please

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

.

Attempting to redi sp erse without h e a t may red u ce th e ap pare n t visco s ity, but not result in a

homog ene ou s mix. B e fore u s ing the a dhe sive, che ck, to ma ke sure that all re sin ha s returned to a t r u e

solutio n and no gel s rem a i n

.

Directions F o r Use

Note: Due to the aggressive nature o f th e solven ts in t he product, it is recommended tha t all ru bber rolls in

the coa t ing h ead be EPDM or a suitab le rubber to resist solvent a tta ck.

Apply Adco te 3220 resin by an y of the c onventional me thods, including gravure coat er, re verse roll coater,

knife and spraying . Dilu tio n may be ne cessary. Ap p l y enough we t coating to d eposit 0.1-0

. 3 dry mils (or

approxima tely 2–6 dry lbs

. per 3000 square feet) and comp letely re move the solvent s. Laminate with hea ted

nip rolls to pro v ide a minimu m glue line te mperature o f 140°F.

The preferred method for b onding is to coat the more stable substrate, hea t the glue to a tempe r ature above

140°F, and laminate

. A heated press can be us ed for general purpose bonding by employing enoug h

pressure to in sure intima te contact be tween the adhes ive and bo th s u rfaces, and holding this p r essure until

the g l ue line r eaches 140°F.

When using Coreactant, u s e the amou nt shown in the Suggeste d Curatives section as a guide. Th e

optimum leve l of coreactant should be determined e x p e rim entally fo r each particular end use. Coating with

coreactant is handled in th e same manner as without . Curing begins after solve n t remova l and continues

slowly at roo m temperatur e. Approximately 7–14 day s are necessary to complete the cure at room

temperature

, but a post cure at ele v a t ed temperatures can reduce th is time.

### Pot Life

It is best not to mix more Adcote 322 0 resi n and corea c tant tha n will be use d in 8 hours. Any mixed

solutio n that i s left ove r sh ould be store d in tig h tly cl ose d contai n e rs an d sho u l d be u s ed wi thin 3 days.

Whe n reu s in g, we re com m end th at you co mbin e th e old mixe d solution with n e wly mixed solution in th e

ratio of 25% old and 7 5 % new, an d mixed thoro ughly

.

Safet y Preca utions

Adcote 3220 resin contains somewhat toxic and/or flammable solvents and suit able handlin g precautions

should be ob served. Do n o t inha le the fumes. Av oid prolonged a nd repeated contact with the skin. Eye

contact must be preven te d. Synthe tic gloves

, face shields, an d aprons impe r meable to th ese solvents
