,Corrosion Resistance WB1K Waterborne Coating
,WB1K Waterborne Coating for Engine Housings
The automotive transmission industry predominantly uses cast aluminum substrates, complemented by plastic components. Holisen has independently developed a one-component waterborne coating system featuring:
- Convenient and efficient application
- Low-temperature curing with fast film drying speed
- Excellent adhesion across multiple substrates
- Outstanding resistance to media, corrosion protection and weathering performance
- Water Resistance (Immersion Method, 23±2℃): ≥240 h, no blistering, peeling or rusting; slight discoloration and gloss loss are acceptable
- Humidity Resistance: No blistering, rusting or cracking on panel surface; very slight discoloration permitted (△Ecmc ≤ 3.0)
- Neutral Salt Spray (NSS) Resistance: 360 h, unilateral corrosion width at scratch ≤ 2 mm; no blistering, rusting or peeling on panel
- Artificial Accelerated Weathering (Q-SUN Tester): 500 h, no cracking, chalking or blistering; very slight discoloration (△Ecmc ≤ 3.0) and gloss loss (≤30%) are acceptable
High-end industrial coatings are widely used in automotive, marine, new energy, electronic information and other sectors. Driven by global economic recovery and manufacturing upgrading, market demand keeps rising steadily.
China ranks first in global coating output for 15 consecutive years, accounting for one-third of the global market. Its high-end industrial coating market will keep expanding as a key growth engine worldwide.
HAOLISEN's customized coating solutions deliver comprehensive protective coatings for robots, pumps & valves, automotive gearboxes, engines and other equipment.
