Choosing a Hydroxyl Level for Hydroxy Functional Acrylic Resin

The information provided does not identify a hydroxyl level for a hydroxy functional acrylic resin. It describes RU-13000, a waterborne aliphatic polycarbonate self-matting polyurethane dispersion. Since no hydroxyl value is listed, use the technical data for the specific acrylic resin and the requirements of the intended coating to set a suitable specification.

What the Available Data Tells You

• No hydroxyl value or hydroxyl content is reported, so the supplied information cannot support a numerical recommendation.
• RU-13000 is identified as a polyurethane dispersion, not as a hydroxy functional acrylic resin.
• The product is listed for wood, plastic, and baking coatings. For color paint, the stated recommendation is to limit pigment content to no more than 15% of the formula.
• Selection requires the technical specification for the target acrylic resin, considered alongside the coating’s performance and application requirements.

Why RU-13000 Does Not Establish an Acrylic Hydroxyl Specification

The RU-13000 product record describes a waterborne, aliphatic polycarbonate polyurethane dispersion with self-matting properties. It mentions air drying, adhesion over solvent-based polyurethane, scratch resistance, recoatability, water resistance, and permeability. These are product and application details; none defines a hydroxyl level for an acrylic resin.

The record also states that RU-13000 can be used with a water-based isocyanate hardener to produce a soft-touch, transparent finish with gloss below 5 degrees. This information applies to RU-13000 and should not be used as a substitute for the hydroxyl specification of a separate acrylic resin.

How to Specify the Level

First confirm the identity of the resin being specified, then obtain its technical data sheet or a written specification from the supplier. Compare the documented hydroxyl value with the intended coating formulation and performance requirements. The information available here does not state an acrylic resin value, so a specific number should not be inferred.

Frequently Asked Questions

What hydroxyl level should I specify for a hydroxy functional acrylic resin?

No value can be determined from the supplied product information. Request the specification for the particular acrylic resin and select a level based on the coating requirements.

Does RU-13000 provide a reference hydroxyl level?

No. RU-13000 is described as a waterborne aliphatic polycarbonate self-matting polyurethane dispersion, and its listed data contains no hydroxyl value.

What performance details are reported for RU-13000?

The product information mentions air drying, adhesion over solvent-based polyurethane, scratch resistance, recoatability, cold and hot water resistance, permeability, and use in wood, plastic, and baking coatings.

Recommendation

Do not assign a numerical hydroxyl level based on this record. It covers polyurethane dispersion RU-13000 rather than hydroxy functional acrylic resin and contains no hydroxyl specification. Obtain the target acrylic resin’s technical data before finalizing the requirement. Guangzhou Guanzhi New Material Technology Co., Ltd. reports offering technical support and formulation references.
