Product Overview

906S is a sag control agent based on an acrylic polymer modified with a polyurea compound. It is supplied as a milky white thixotropic fluid at 58-62% solids, with structure finer than 10 microns. It raises vertical film build, orients metal pigment, stops settling and still gives excellent appearance and gloss, which is why it is written for high quality automotive solid colour paints and varnishes.

Key Benefits

58-62% solids, the highest of the three sag control grades
Fineness below 10 microns protects gloss and appearance in clearcoats
Increases achievable film thickness on vertical surfaces
Orients metal pigment as well as controlling sag
Prevents settling in the can

At A Glance

Chemistry: Polyurea-modified acrylic polymer (SCA)
Family: Sag Control Agents
Category: Sag Control Resins
Positioned against: Nuplex 91795
Appearance reference: Milky white thixotropic fluid

Who It Is For

Automotive OEM and refinish coating formulators
Producers of high-gloss industrial finishes

Problems It Solves

Sagging that caps the film build achievable in one pass
Metal pigment sitting at random angles and dulling the flop
Thixotropes that cost gloss in a clearcoat

Application Scenarios

Automotive solid colour topcoats
Automotive clearcoat and varnish
Metallic basecoats needing both orientation and sag control

Recommended Dosage

All dispersant and additive dosage figures below are quoted exactly as the source data sheet quotes them. Dispersant figures are percentages on pigment weight, not on the total batch. The published values are empirical, so confirm the optimum with a dosage ladder in your own system.

On finished formulation	8-12%

Use Guide

Dose at 8-12% on the finished formula.
Because the structure is finer than 10 microns, it can be used in clearcoat without the haze a coarser SCA would bring.
Store below 30C; shelf life is 12 months.

Quality Control On Your Side

Sag bar test at the target build on a vertical panel
Gloss and distinctness of image on cured clearcoat panels
Flop measurement on metallic panels

Comparison

How It Compares With The Alternatives

Technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named commercial product.

908R	908R is a hydroxy-functional paste that crosslinks into 2K polyurethane; 906S is a higher solids fluid with finer structure.
904R	904R is specified for metal pigment orientation and CAB compatibility; 906S is the high gloss automotive grade.
Fumed silica	Keeps gloss and distinctness of image that silica loading tends to cost.

Questions

Anti-Sagging Resin 906S Questions

Can 906S be used in clearcoat?

Yes. It is written for high quality automotive solid colour paints and varnishes, and the sub-10 micron fineness is what makes clearcoat use possible.

What is the recommended dosage?

8 to 12% on the finished formulation.

Does it help metallic orientation?

Yes. Orientation of metal pigments is listed among its characteristics, alongside sag control and anti-settling.

What solvent is it supplied in?

Xylene / CAC 85/15.
