Underbody Coating
UNDERBODY COATING:
underbody coating is painted or sprayed in claddng to body frame .underbody coating provides longterm protection from corrsion to cars underbody and innerparts.
In this avarge thickness value has considered for all areas.in this thickness size it used to long life of corrosion resistence. so that underbody coating life is depants on thickness and material.
- thickness measured using in (dry flim thickness metar)-ELCOMETER
- composition analyzed using(material)in-NITON XLT
TYPES OF UNDERBODY COATING:
- RUBBERIZED UNDERCOATING
- POLYURETHENE UNDERCOATING
- WAX OR PARATFIN-BASED UNDERCOATING
- ASPHALT-BAST UNDERCOATING
its all types only difference on composition of materials in undercoating
ADVANTAGES:
- protect on body frame and innerparts against rust and corrosion
- reduces the noise vibrations harshuness levals
DISADVANTAGES:
Its before applying the underbody coating the rust must be removed. otherwise it will no use for coating longlife.
