CORODUR® SP 121

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 5 – 1,6 - 4

MATERIAL REVIEW

SP 121 shows very good bonding in connection with a high deposition rate. The high Carbon content gives a extremely high hardness and abrasion resistance. For corrosion protection apply on top Zinc or Aluminum arc coatings. It can be coated either as a one layer rough coating (A) showing good bonding and very high roughness or as a two layer system with a first dense coating (B) with a top coat of high roughness as above. This results in a very good bonding and into dense coatings. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying

APPLICATION

In particular used as very rough antiskid coating on walkways in industry and on ship decks.
