JONCRYL® 910 is a hydroxyl functional, fast drying, acrylic polyol for higher solids polyurethane coating applications. This material employs a novel technology, which makes this polyol more reactive with isocyanate crosslinking agents. The result is the ability to formulate fast drying polyurethane coatings with good pot life and excellent dry time characteristics for maintenance, transportation and other applications, at VOC levels as low as 3.2 pounds per gallon without exempt solvents.

JONCRYL 910 is recommended for applications such as:

• Interior/exterior general metal coating applications
• Automotive OEM and refinish applications
• Interior/exterior plastic component coating applications

Features & Benefits

• Outstanding gloss
• Color retention
• Outstanding durability
• Very fast dry time
• Early hardness development
• Good pot life

Performance Data

Cure/Dry Characteristics

The following graph compares the dry times of white topcoat formulations based on JONCRYL 910 with a competitive acrylic polyol that yields a similar viscosity/VOC. The competitive formulation is catalyzed with 0.005% dibutyltin dilaurate on vehicle weight solids. The JONCRYL 910 formulation is un-catalyzed. Both systems are approximately 3.2 lbs/gal VOC at 200 cps.

UV Gloss Retention

QUV gloss retention results were obtained using UVA-340 bulbs with 4 hours of light at 60°C followed by 4 hours of condensation at 40°C. Both coatings are white topcoat formulations at a 17%PVC with BASONAT® HI 100 as the crosslinker and n-MAK as the formulation solvent. The competitive formulation is catalyzed with 0.005% dibutyltin dilaurate on vehicle weight solids. The JONCRYL 910 formulation is un-catalyzed. No UV light absorbers were used.
