Isopropanol (2-propanol, IPA) supplied by Shandong Junteng Chemical is a premium low-toxicity, medium-volatility polar solvent with full miscibility with water, hydrocarbon oils and all mainstream coating resins. Our factory-grade 99.9% high-purity IPA is tailor-made for architectural coatings, industrial topcoats, automotive paints, wood varnishes and printing inks, widely recognized by coating manufacturers nationwide and overseas for stable quality, low impurity and cost-effective bulk supply.

1. Core Diluent & Universal Resin Solvent 

1.1 Resin dilution & viscosity adjustment

• Nitro wood lacquer & furniture varnish: Thicken resin slurry into ideal spraying consistency, deliver crystal-clear finish without yellowing;
• Waterborne hybrid coatings: Premium co-solvent to balance hydrophilic & hydrophobic components, solve layering and poor fusion issues.

1.2 Compound solvent blending formula

2. Pre-coating Degreasing Cleaning Agent 

• Metal substrates (steel, aluminum, iron): Fully strip machining oil, cutting fluid, anti-rust oil and fingerprint grease;
• Plastic substrates (ABS, PC, PVC): Remove mold release agent without cracking or embrittling plastic surfaces;
• Glass, hardware and decorative parts: Erase silicone pollutants that cause fish-eye defects. Advantage: Fast air-dry, zero residual oil film, mild irritation vs ketone solvents, compliant with workshop environmental standards.

3. Anti-blushing Agent & Leveling Booster

• Moderate evaporation speed optimizes surface leveling, smooth out brush marks and orange peel texture;
• Static dissipation reduces paint mist adsorption of dust, lowering polishing rework cost;
• Low residual odor after full curing, ideal for furniture, food-contact and indoor green coatings.

4. Printing Ink & Clear Varnish Thinner

4.1 Industrial printing inks

4.2 Transparent topcoat & matte varnish

5. Production Equipment Washing Solvent

• Quickly dissolve semi-dried residual paint, easy distillation recovery to cut raw material cost;
• Less corrosive than ketone solvents, extend service life of spraying equipment and reduce maintenance expense.
