Coating Range

Water-Based Acrylic Emulsion

TT-AC-909

Class F (155°C), 47%±2% solids, multi-layer, solvent-resistant and anti-yellowing — non-rigid in winter, non-sticky in summer.

Water-Based Polyurethane Resin

TT-PU Series

Class F (155°C), high strength and abrasion resistance, smooth surface, good low-temperature performance.

Water-Based Modified Epoxy Resin

TT-EP Series

Heat resistance up to 350°C+, anti-yellowing and highly water-resistant for high-temperature sleeves.

Polyurethane Topcoats (2- / 3-component)

TT-PU-90 / 9055

High-solid aliphatic PU topcoats — anti-yellowing, low-temperature elasticity, multi-layer compatible.

Flame-Retardant Acrylic Coating

TT-AC-FR

Halogen-free, adjustable rating up to UL94 V-0 for flame-retardant sleeves.

Water-Based Silicone Base Coat

TT-WBS-01

VOC ≈ 0 first-layer primer, flexible and compatible with acrylic / PU topcoats.

Tested & Validated

Real results from Tentuo's R&D center and customer lines on coating build, solvent resistance and high-temperature baking.

2 / 3 layer
Coating uniformity

Three-coat samples build a denser, crack-free film that survives sleeve bending.

48 h
Solvent-soak resistance

After 48 h in xylene / ester-alcohol solvents: no softening, no peeling.

180°C × 48 h
High-temperature bake

Stable golden hue, no cracking or chalking — keeps Class F (155°C) insulation.
