With environmental regulations worldwide tightening VOC limits, the coatings industry is accelerating its shift toward waterborne solutions. In the 3C electronics and small appliance sector, coatings must do more than meet compliance—they must also deliver top-tier performance in gloss, hand touch, abrasion resistance, and adhesion.

Technical Control Water-based Plastic Coatings Solution

Technical Control PU 639D is an anionic aliphatic waterborne polyurethane dispersion. It offers outstanding optical performance, a distinct soft hand feel, and well-rounded physical properties—making it an ideal solution for waterborne plastic paint applications that balance environmental responsibility with high performance.

Product Highlights & Advantages

Excellent Optical Performance

The structure of form film gives high gloss to the finished surface. It also has excellent compatibility with other components inside the formulation, enabling possibilities to achieve a variety of finishes—from high-gloss to matte—so you can achieve the surface effect according to different application needs.

Soft Hand Touch with Tack Free Surface

The coating provides a soft, smooth, comfortable hand touch and maintains a tack-free surface, improving the user’s experience during contact and gripping.

Outstanding Abrasion Resistance

The film forms a stable physical crosslinked network after curing, resulting in reliable wear resistance. It helps protect against daily friction while keeping the surface looking bright and fresh.

Strong Adhesion

Provides excellent adhesion to common plastic substrates such as ABS, PC, and ABS+PC. Given this, formulators can design a simpler and more stable formula by reducing the use of adhesion-promoter.

Dry & Wet Resistance

Considering the situation such as sweat exposure and routine cleaning. Even under wet conditions, the film maintains structural stability and resists whitening, softening, or abrasion during wiping, helping the coating stand up to sweat and repeated cleaning.

Applications

3C Consumer Electronics

Suitable for phone cases, tablet back covers, mouse bodies, keyboards, and game controllers. For high-frequency use, it balances premium appearance with durability—especially with substrates like ABS, PC, and ABS+PC.

Premium Small Appliances

Ideal for hair dryers, electric razors, coffee machines, and similar products. Helps maintain coating stability and consistent appearance across varied environments such as bathrooms and kitchens.

Rigid Plastic Parts

Works well for surface treatment of PVC decorative sheets and ABS boards—combining protective performance with aesthetic enhancement.
