KD BOND + SEAL PRIMER INFORMATION

Optimisation Table
Surface/material Optimisation steps Remarks

Aluminium (AlMg3, AlMgSi1) B+S Primer for Metal If necessary, first sand lightly ith sanding eece.
Aluminium anodised B+S Primer for Metal –
If necessary, first sand lightly ith sanding eece.
Steel (St 37, etc.) B+S Primer for Metal In case of steel components in danger of corrosion:
2-comp. PU or epoxy corrosion protection required.
Stainless steel B+S Primer for Metal –
Steel, galvanised or hot galvanised B+S Primer for Metal If necessary, first sand lightly ith sanding eece.
2-comp. top coats (PU, epoxy), 2-comp. water based – Due to the wide variety of enamels, this information
primers and enamels, KTL, primers (EP/2-comp.) is for reference only, preliminary testing required.
Preliminary testing recommended for applications
Powder coated surfaces –
with high forces or in moist ambient conditions.
GFK (unsaturated polyester), gelcoat side or SMC If necessary, first sand lightly ith sanding eece.
1. Sand with S 80
GFK (unsaturated polyester), layup side –
2. B+S Primer for P/W/S

Glass (mineral) –
(opaque covering).
Glass ceramics – –
1. Dedust
Wood and wood products (particle boards) untreated –
2. B+S Primer for P/W/S
1. Dedust
Natural stone Possible discoloration in case of natural stone (marble).
2. B+S Primer for P/W/S
1. Dedust –
Concrete, mineral mortar and plaster
2. B+S Primer for P/W/S
Preliminary testing required.
Textiles, eece B+S Primer for P/W/S
In some cases, meshing of adhesive ith the textile is sufficient.

Note:
The above information always relates to the surface of the component (e.g. steel coated with 2-component epoxy enamel: see 2-comp. top coats).
Prior to starting optimisation procedures, all components must be clean, dry and free of dust, grease and oil. nstable or loose layers must be removed first.
Clean surface with cleaning agent to remove oil and grease. Allow to dry. Afterwards, apply a thin coat of B+S Primer for Metal or Primer for
Plastic/Wood/Stone evenly with a brush.

Important:
Prior to the next step, the previously applied layer must have set and dried completely. Observe aeration times!
