Reliable adhesion, fast drying, and stable metallic appearance are important when formulating coatings for plastic and metal substrates. KN1115F is a hydroxyl acrylic resin for plastic coatings designed for PC solid-color coatings, aluminum-pigmented paints, and dual-curing primers.
The resin offers fast drying, good silver pigment orientation, strong adhesion to ABS and PC, good recoatability, boiling-water resistance, and reliable adhesion to 304 stainless steel.
Fast Drying and Good Silver Alignment
KN1115F is designed to support efficient coating application.
Its fast-drying performance can help shorten processing time. In addition, the resin provides good silver pigment orientation, which is especially important in aluminum-pigmented coatings where uniform pigment alignment affects the final metallic appearance.
In the reference metallic coating test, the silver pigment showed high whiteness and uniform gloss, while the film surface remained smooth and free from cratering.
Strong Adhesion on ABS, PC and Stainless Steel
Adhesion is one of the key challenges in plastic coating systems.
KN1115F provides good adhesion to ABS and PC substrates, while also offering good recoatability. Moreover, the product document states that it shows good adhesion to 304 stainless steel and good resistance to boiling water.
This makes the resin suitable for formulators working with different plastic and metal coating systems.
Recommended Applications
KN1115F is recommended for:
- PC plastic solid-color coatings
- Aluminum-pigmented coatings
- Dual-curing primers
Therefore, the resin can serve as a practical raw material for coating manufacturers that require a balance of drying speed, adhesion, metallic appearance, and resistance performance.
Typical Technical Properties
| Property | Specification |
|---|---|
| Composition | Acrylic copolymer |
| Appearance | Clear and transparent |
| Viscosity at 25°C | 6–10 Pa·s |
| Acid Value | 1–4 mg KOH/g |
| Solvent | BAC / MIBK |
| Color | ≤1 Fe-Co |
| Solid Content | 50 ± 2% |
| Hydroxyl Value | 20 |
These values provide formulators with a technical reference when evaluating KN1115F in their own coating systems.
Reference Coating Performance
The product document also provides reference performance data using ABS as the substrate.
Typical test results include:
- Surface dry: 15 minutes
- Pencil hardness: H / HB under the stated test conditions
- 60° gloss: 70
- Cross-cut adhesion: 100%
- Silver pigment orientation: Excellent
- Leveling: Smooth and free from cratering
- Ethanol resistance: 200 wipes at 13 μm
- Acid resistance: Passed the stated 10% H₂SO₄ test
- Alkali resistance: Passed the stated 5% NaOH test
These results are based on the reference formulation and test conditions. Therefore, coating manufacturers should confirm final performance in their own formulation, substrate, and production environment.
Packaging and Storage
KN1115F is supplied in 190 kg drums.
The recommended storage conditions are a cool, well-ventilated area away from heat and ignition sources. Keep the container tightly closed.
The stated shelf life is 24 months from the production date.
