Cor­ro­si­on Protection

Cor­ro­si­on Protection

Accord­ing to DIN EN ISO 8044- 2020, cor­ro­si­on is the reac­tion of a metal­lic mate­ri­al with its envi­ron­ment, which cau­ses a mea­sura­ble chan­ge in the acti­ve sub­s­tance and can lead to impairment of the func­tion of a metal­lic com­po­nent or an ent­i­re system.

For func­tio­n­al cor­ro­si­on pro­tec­tion, we not only offer our cor­ro­si­on pro­tec­tion pro­ducts, but also want to sup­port with rele­vant know-how.

Read more about this in our Let­ter of recom­men­da­ti­on cor­ro­si­on pro­tec­tion.

The decisi­ve fac­tor is the cor­ro­si­vi­ty cate­go­ry to be achie­ved as well as the dura­ti­on of pro­tec­tion to be achieved

The fol­lowing docu­ment is inten­ded to pro­vi­de an insight into typi­cal pretre­at­ment and coa­ting opti­ons to achie­ve a required/suitable cor­ro­si­on pro­tec­tion. This matrix is to be unders­tood as a recom­men­da­ti­on only and in no way pro­vi­des a gua­ran­tee for achie­ving the desi­red pro­tec­tion category.

The qua­li­ty and thus asso­cia­ted pro­tec­tion dura­ti­on are stron­gly depen­dent on various fac­tors such as

  • Qua­li­ty of the sub­stra­te (com­po­si­ti­on of the alloy)
  • Qua­li­ty and imple­men­ta­ti­on of the pretreatment
  • Qua­li­ty of the zinc coa­ting (thic­kness, passivation…)
  • Selec­tion of pow­der coa­tings and app­lied coa­ting thicknesses
  • con­struc­tion of the struc­tu­re (see con­struc­ti­ve mea­su­res cor­ro­si­on protection)
  • Dama­ge of the paint surface
  • etc.
 

Regu­lar pro­cess con­trol is the­re­fo­re essen­ti­al to pro­du­ce high qua­li­ty and long life.

The fol­lowing docu­ment is inten­ded to pro­vi­de an insight into typi­cal pretre­at­ment and coa­ting opti­ons to achie­ve a required/suitable cor­ro­si­on pro­tec­tion. This matrix is to be unders­tood as a recom­men­da­ti­on only and in no way pro­vi­des a gua­ran­tee for achie­ving the desi­red pro­tec­tion cate­go­ry.   (You can find the docu­ment here: Down­load)

Regu­lar pro­cess con­trol is the­re­fo­re essen­ti­al to pro­du­ce high qua­li­ty and long life.

It should also be noted that the cor­ro­si­on pro­tec­tion clas­ses are not app­li­ca­ble in the case of very seve­re cor­ro­si­on loads, long pro­tec­tion peri­ods and spe­cial loads. In the case of the­se loads and con­di­ti­ons, the necessa­ry mea­su­res must be deter­mi­ned in each indi­vi­du­al case. The pro­tec­tion peri­od to be achie­ved by the coa­ting sys­tem must alrea­dy be known during plan­ning and design. In gene­ral, the pro­tec­tion peri­od is shor­ter than the expec­ted ser­vice life.

Con­clu­ding remarks:

  • The matrix repres­ents a mini­mum level for achie­ving the pro­tec­tion dura­ti­on. Fur­ther wet-che­mi­cal pretre­at­ments such as mul­ti­me­tal-capa­ble nano­cer­a­mics like Bru­gal© (No Rin­se) can incre­a­se the pro­tec­tion dura­ti­on by up to 50%.
  • In the case of hot-dip gal­va­ni­zed com­pon­ents, the zinc thic­kness should be mea­su­red in advan­ce as a pro­cess con­trol, as the out­gas­sing beha­vi­or can be stron­gly depen­dent on this. In addi­ti­on, the gal­va­ni­zer should at best indi­ca­te whe­ther pas­siva­ti­on is pre­sent on the gal­va­ni­zed sur­face. In any case, sweeping and out­gas­sing in the fur­nace is recommended.
 

In the case of sharp-edge­d/la­ser­e­d/­pun­ched com­pon­ents, burrs should always be remo­ved and the edges roun­ded. In addi­ti­on, the sur­face should be free of sca­le and oxi­da­ti­on layers!

BRUGAL® TREAT 050

Mul­ti-metal pretre­at­ment (chro­me-free)

 

Pas­siva­ti­on befo­re painting

App­li­ca­ti­on by dipping or spray­ing (chro­me-free)

 

 

PRODUCT DESCRIPTION

BRUGAL® TREAT 050 is a pas­sivat­ing agent that impro­ves adhe­si­on and has been spe­cial­ly deve­lo­ped for paint pretre­at­ment. It can be used in paint lines in both spray and dip processes.

BRUGAL® TREAT 050 reacts with the metal sur­face by pas­sivat­ing it, thus impro­ving paint adhesion.

The pro­duct is par­ti­cu­lar­ly sui­ta­ble for the tre­at­ment of steel and phos­pha­ted steel. Howe­ver, it is also sui­ta­ble for gal­va­ni­zed steel, zamak, alu­mi­num and their alloys.

The pre­pa­ra­ti­on is desi­gned for pain­ting sys­tems with liquid paints, paints in pow­der form and by cata­pho­re­sis. For more infor­ma­ti­on, plea­se con­ta­ct the tech­ni­cal service.

 

 

TECHNICAL AND ECONOMICAL ADVANTAGES

  • Does not con­tain chromium
  • Impro­ves paint adhesion
  • Pre­vents delamination
  • Excel­lent cor­ro­si­on protection
  • No rinsing necessary
  • Com­pa­ti­ble with a wide varie­ty of liquid or pow­der paints
 

APPLICATION FORMS

BRUGAL® TREAT 050 is app­lied by immer­si­on or by spray gun in baths dilu­t­ed with demi­ne­ra­li­zed or distil­led water. No rinsing is requi­red after app­li­ca­ti­on, only dry­ing, after which the pre-trea­ted pro­duct is rea­dy for painting.

The con­cen­tra­ti­on recom­men­ded for the bath is 4–6% by volu­me, depen­ding on the equip­ment and app­li­ca­ti­on system.
