KN6532P is a hydroxyl acrylic resin for coating formulations that require high gloss, good leveling and fast drying. It also offers excellent chemical resistance. Recommended applications include appliance clearcoats, automotive refinish coatings and pigmented coatings for light-duty corrosion protection.
KENXON supplies this acrylic copolymer as a clear, transparent resin solution with a solids content of 65 ± 2%. In addition, the product document includes a two-component white paint reference formulation and its coating test results.
High Gloss and Smooth Leveling
KN6532P combines high gloss with good leveling. These properties make it an option for formulations that require a smooth, attractive finish.
In the supplied reference formulation, the coating achieved a 60° gloss value of 85. The visual leveling assessment also recorded a smooth surface without craters.
Furthermore, the coating passed the visual assessment for film fullness and distinctness of image. These results provide a useful starting point for manufacturers developing decorative and protective finishes.
Fast Drying and Hardness Development
Fast drying is one of the key features of KN6532P hydroxyl acrylic resin.
The reference coating recorded a surface-dry time of 20 minutes using the cotton-ball method. It also reached the listed hard-dry condition after 24 hours, with no fingerprint under the finger-pressure test.
Meanwhile, pencil hardness increased from below HB at eight hours to H at 24 hours. This shows why the evaluation time matters when comparing coating hardness.
These figures describe the supplied reference coating. Actual drying and hardness development depend on the complete formulation and processing conditions.
Chemical Resistance
KN6532P offers excellent chemical resistance. The product document supports this feature with acid and alkali immersion results from the reference formulation.
| Test | Exposure Conditions | Reported Result |
|---|---|---|
| Acid resistance | 10% sulfuric acid for 72 hours | Passed: no blistering, peeling or discoloration |
| Alkali resistance | 5% sodium hydroxide for 48 hours | Passed: no blistering, peeling or discoloration |
For these evaluations, the document specifies baking at 70°C for 60 minutes on sanded tinplate. The specimens then stood for 24 hours before resistance testing.
Therefore, manufacturers should use these conditions when reviewing the results and planning comparison trials.
Recommended Coating Applications
KENXON recommends KN6532P for three main application areas:
- Appliance clearcoats
- Automotive refinish coatings
- Pigmented coatings for light-duty corrosion protection
For appliance clearcoats, the product offers a combination of gloss, leveling and chemical resistance. Meanwhile, automotive refinish formulators can evaluate its fast-drying characteristics and surface appearance.
The product also provides an option for light-duty anti-corrosion color coatings. However, the final coating system should match the intended substrate and service conditions.
Typical Resin Properties
| Property | Typical Value |
|---|---|
| Composition | Acrylic copolymer |
| Appearance | Clear and transparent |
| Solids content | 65 ± 2% |
| Viscosity at 25°C | 2.5–5.5 Pa·s |
| Acid value | 3–6 mg KOH/g |
| Color, Fe-Co scale | ≤1 |
| Solvents | Xylene, butyl acetate and toluene |
These values describe the resin as supplied. They are separate from the coating results obtained with the reference formulation.
Reference Coating Performance
The document provides the following additional results for its two-component white paint formulation.
| Test Item | Reported Result |
|---|---|
| Cross-cut adhesion | 100%, as reported in the document |
| Impact resistance | Passed the specified ≥50 cm requirement |
| Flexibility, bend test | 1 mm |
| Film fullness and distinctness of image | Passed |
| Leveling | Smooth surface without craters |
| QUV exposure | Passed 600 hours, with no discoloration or peeling and gloss loss ≤1% |
The QUV result reflects the laboratory exposure described in the document. It does not establish a specific number of years of outdoor service.
For formulation development, request the complete reference formula and test details from KENXON. Then verify performance under your own application conditions.
Compatibility and Formulation Support
The compatibility table lists KN6652P, KN6701P and KN7548P as compatible with KN6532P.
It also lists several compatible solvents, including xylene, trimethylbenzene, butyl acetate, cyclohexanone, isobutanol and n-butanol.
In addition, the reference white paint formulation uses an N3390 curing agent. This provides a starting point for evaluating KN6532P in a two-component system.
Before production, confirm the resin blend, curing-agent ratio and thinner package through formulation trials.
Packaging and Storage
KN6532P comes in 200 kg drums. Its stated shelf life is 24 months from the production date under the recommended storage conditions.
Keep containers tightly closed in a cool, ventilated place, away from heat and ignition sources. For detailed handling information, refer to the product’s safety data sheet.
