Proper substrate preparation plays an important role in the durability and adhesion of architectural coating systems. The SCV series provides water-based primer emulsion for architectural coatings with different functions for interface treatment, transparent sealing, substrate strengthening, and alkali resistance.
SCV-8011, SCV-8015, and SCV-8016 are designed for different stages and substrate requirements. Therefore, coating manufacturers can select the appropriate emulsion according to penetration, adhesion, sealing, or anti-alkali performance.
SCV-8011 – Interface Agent Emulsion
SCV-8011 is a high-performance emulsion developed specifically for interface-agent applications.
Its main advantages include:
- Good penetration
- Strong adhesion
- High bonding strength
- Improved flexural strength of cement-based products
- Good low-temperature film formation
The product is especially relevant when the coating system needs stronger bonding between the substrate and subsequent coating layers.
Typical technical properties include:
| Property | SCV-8011 |
|---|---|
| Appearance | Milky white liquid with slight blue tone |
| Solid Content | 49.0–51.0% |
| Viscosity | 200–1000 mPa·s |
| pH | 7.0–9.0 |
| Particle Size | 0.1–0.2 μm |
| Minimum Film-Forming Temperature | 16°C |
In addition, the product shows 48-hour Ca²⁺ stability without separation, sedimentation, or flocculation under the documented test conditions.
SCV-8015 – Clear Sealing Primer Emulsion
SCV-8015 is designed as a transparent sealing primer emulsion.
The product provides good adhesion and penetration on different substrates while helping strengthen the base material. Its main application advantages are:
- Good penetration
- Improved substrate strength
- Enhanced adhesion
This makes SCV-8015 suitable for coating systems where substrate sealing and reinforcement are important before applying subsequent decorative layers.
Its typical properties include:
| Property | SCV-8015 |
|---|---|
| Appearance | Blue-tinted translucent liquid |
| Solid Content | 40.0–42.0% |
| Viscosity | <500 mPa·s |
| pH | 7.0–9.0 |
| Particle Size | 0.1–0.2 μm |
| Minimum Film-Forming Temperature | 20°C |
For formulators that need a low-viscosity primer emulsion with penetration and sealing capability, SCV-8015 provides a focused option.
SCV-8016 – Alkali-Resistant Primer Emulsion
SCV-8016 is a next-generation alkali-resistant primer emulsion developed with functional additives and epoxy-group functional monomers.
Its key characteristics include:
- Strong early resistance to salt and alkali migration
- Good adhesion
- Fast construction and shorter curing period
- Resistance to masking-tape peeling
- Alkali resistance
- Water resistance
- Good penetration
- Resistance to salt precipitation
It can also be applied to different substrate types.
Typical technical data include:
| Property | SCV-8016 |
|---|---|
| Appearance | Milky white liquid with blue tone |
| Solid Content | 46.0–48.0% |
| Viscosity | 1000–4000 mPa·s |
| pH | 7.0–9.0 |
| Particle Size | 0.1–0.2 μm |
| Minimum Film-Forming Temperature | 30°C |
SCV-8016 also shows 48-hour Ca²⁺ stability without separation, sedimentation, or flocculation under the stated test conditions.
How to Choose Between SCV-8011, SCV-8015 and SCV-8016
| Product | Main Function | Best Fit |
|---|---|---|
| SCV-8011 | Interface bonding and penetration | Interface-agent systems, cement-based substrates |
| SCV-8015 | Transparent sealing and substrate strengthening | Clear sealing primer systems |
| SCV-8016 | Alkali resistance and substrate protection | Alkali-resistant architectural primers |
In simple terms:
- Choose SCV-8011 when bonding strength and interface adhesion are the main priorities.
- Choose SCV-8015 when you need transparent sealing, penetration, and substrate reinforcement.
- Choose SCV-8016 when alkali resistance, water resistance, and early salt-resistance performance are more important.
Packaging and Storage
All three products should be stored in a dry, ventilated indoor environment and protected from direct sunlight.
The documented transportation and storage temperature is:
5–35°C
The stated shelf life is:
6 months from the packaging date
Packaging options include:
- 50 kg plastic drums
