Core Principle

The cutting-edge technology of HQ-9780 lies in its emulsion molecules. Unlike traditional emulsions that achieve matte effect by adding matting powder, this product adopts a collocation of emulsion molecules with different particle sizes to form natural diffuse reflection on the coating surface. It delivers delicate and uniform full matte finish without extra matting powder. Equipped with built-in self-crosslinking technology, the formed coating film features lower water permeability and outstanding waterproof performance, fundamentally reducing later water seepage and peeling issues.

It has a clear core positioning — specially developed for matte clear topcoats, ideal for coating applications requiring prominent base texture and low-key delicate texture, such as topcoat protection for exterior stone-like coatings and artistic coatings.

Reliable Performance Reflected by Key Specifications

1. Diffuse Reflection Technology with Multi-Size Emulsion Molecules

It scatters light without matting powder, with gloss at 0° ≤ 3, realizing soft matte visual effect without glaring reflection.

2. Self-Crosslinking & Low Tg Design

With Tg of 28℃ and MFFT of 0℃, it allows safe construction for the final topcoat before frost. The crosslinked dense film delivers water permeability below 0.08 mL and no whitening in rainy seasons.

3. Rigorous Triple Resistance Test Results

Water whitening resistance: ΔE ≤ 0.3 after 96h water immersion, fully recoverable after wiping dry

Stain resistance: Reflectance reduction ≤5%, black stains from outdoor air conditioner units can be easily washed off

Weather resistance: No chalking or yellowing after 1000h QUV aging, meeting the highest grade of GB/T 1865 standard.

4. Excellent Compatibility with Various Systems

Compatible with sand-in-water coatings, crystal stone coatings, limestone coatings, stone-like coatings and more. No color absorption or mottling, on-site color mixing only takes 5 minutes.

Five Core Advantages

1. Stable Water & Moisture Resistance with Superior Wet Adhesion

What troubles exterior coatings most? Surface whitening, blistering and peeling after rain! HQ-9780 boasts outstanding resistance to water whitening; no hazy white film will form even under long-term dampness or rain immersion. Its ultra-high wet adhesion enables tight bonding between coating and substrates (sand-in-water coatings, limestone coating surfaces etc.), preventing peeling under wind and rain and cutting later maintenance costs.

2. Natural Matte Finish with High Light Transmittance to Highlight Underlying Texture

Many matte emulsions either produce overly dull matte effect or feature excessive hiding power that covers the texture of underlying stone-like coatings. HQ-9780 strikes a perfect balance: soft natural matte without heavy depressing appearance, plus high light transmittance to clearly reveal substrate textures such as stone texture of sand-in-water coatings and particle feel of crystal stone coatings, delivering authentic and layered decorative effect.

3. Durable Stain Resistance for Effortless Exterior Wall Cleaning

Dust and dirt accumulation on exterior walls leads to high cleaning costs and labor work. HQ-9780 features excellent stain resistance to repel dust and oil contamination. Surface dirt can be easily washed away by rainfall, keeping exterior walls clean for long term and greatly reducing post-construction cleaning and maintenance expenses.

4. Low-Temperature Film Forming & Strong Weather Resistance Against Extreme Climates

Common emulsions fail to form films in cold northern winters or crack under high-temperature exposure at high altitudes. HQ-9780 solves such issues with MFFT of 0℃, supporting normal film formation in cold winter without waiting for temperature rise. Its premium weather resistance withstands high-temperature sunlight, low-temperature frost and rain erosion, extending coating service life and lowering rework risks.

5. Wide Formula Compatibility to Avoid Formulation Matching Troubles

The biggest headache for construction projects is poor compatibility between emulsions and finished coatings. HQ-9780 achieves perfect compatibility with mainstream coatings including sand-in-water coatings, crystal stone coatings and limestone coatings. Direct mixing is available without repeated formula adjustment, greatly boosting construction efficiency for coating manufacturers and construction teams.

Real Application Case

Final Topcoat Construction for a High-End Residential Community in Shenyang at -5℃

Construction Period: Late November, nighttime temperature -5℃

Substrate: Sand-in-water multicolor coating

Difficulty: Tight construction schedule; traditional matting powder topcoats cannot form films below 5℃

Solution: Direct roller coating with HQ-9780, film forms normally at 0℃. The coating film remained intact with uniform gloss even under strong wind at -7℃ the next day. The water permeability tested on site by Party A was 0.06 mL, passing one-time acceptance inspection.

Construction Tips: 3 Steps to Achieve Premium Matte Texture

1. Water dilution ratio ≤5%. Add water after pouring emulsion to reverse dilution and prevent emulsion breaking.

2. Single wet film thickness 80-100 μm, apply one horizontal and one vertical coat to avoid bright marks from repeated brushing.

3. Recoating interval ≥4h at 25°C, extend interval under low temperature. Avoid rain and frost during film formation.
