**Recommend increased active matter grades designated "H" or "2H"
 CHARTSIL: Use Procedure Considerations

1.

Liquid Chartwell is largely in pores of silica, not on the exterior of the Chartsil particle.

2. Liquid Chartwell has high surface tension. For liquid to be released and pass into the powder coating system, the silica carrier must be crushed.
3. Set extruder for maximum shear and maximum torque.*
4. Recommended use level is 0.5 - 1.0 phr. (2H), 1.0-1.4 phr. (H), and 1.4-2.8 phr. (others)

 ORGANOREACTIVE GROUPS:

 -(CH 2) x SH, X<6

 B-505.1

 -(CH 2) xNH2, x<4

  B-515.1

 -CH(OH)-CH(OH)-COOH

 C-523.2

 -(CH2)xCOOH, X=4-6

 B-525.1

 -(CH2)xCOOH, x>10

 C-531.1

 Benefits:

1. Powder Coatings
• Improved corrosion resistance (salt fog), reduced creep at the scribe.

2. Rubber
• Improved adhesion

• Improved abrasion resistance

• Improved tensile and tear strengths

*Alternatively premix Chartsil with resin/ pigments in a high shear mixture, ie Henschel, Banbury or similar. Add premix to extruder and compound as usual.
