Sag Control Resins

Three polyurea and urethane sag control agents for automotive and industrial coatings, each with a different structure size and a different job.

The Range

Every Sag Control Resins Grade We Publish

Sag control agents are not interchangeable. One of these three crosslinks into a two-component polyurethane, one is fine enough for clearcoat, and one is written around metal pigment orientation and CAB compatibility. Picking the wrong one costs either gloss or film build.

Problems This Family Solves

  • Film build is capped by sagging before the corrosion specification is met
  • A thixotrope is costing gloss or distinctness of image in a clearcoat
  • Metal pigment will not hold its orientation through flash-off
  • An inert thixotrope is weakening the cured film

Who It Is For

  • Automotive OEM and refinish coating formulators
  • Industrial and protective coating producers working at high film build
  • Formulators using CAB in metallic basecoats

Why Buyers Choose This Range

  • Thixotropy index published for all three grades at stated spindle and speed
  • Fineness published, which is what decides clearcoat suitability
  • 908R carries an OH value so it crosslinks rather than sitting inert
  • Solids, solvent blend, storage window and shelf life all stated

Typical Application Scenarios

  • Two-component polyurethane topcoat needing 7-11% of a hydroxy-functional SCA
  • Automotive clearcoat where the SCA must stay below 10 microns
  • CAB-based metallic basecoat needing orientation and sag control together
Questions

Sag Control Resins Questions

Which of the three grades crosslinks into the coating?
908R. It carries an OH value of 100 mg KOH/g on solids, so it takes part in the two-component polyurethane crosslink.
Which is suitable for clearcoat?
906S, at a fineness below 10 microns and 58-62% solids.
Which one should be used for metallic orientation?
904R is written for coatings containing metal pigment and is specifically noted for compatibility with CAB.
What packing is available?
908R and 906S are supplied in 200 kg drums. Packing for 904R is confirmed per order.
