TPU fuel injection, oil, adhesion solution

TPU as an elastomer is a material between rubber and plastic. It is oil-resistant, water-resistant, and mold-resistant. TPU's bearing capacity, impact resistance and shock-absorbing performance are outstanding. TPU also has good weather resistance, abrasion resistance, tear resistance, and excellent resistance to high-energy radiation. TPU products can be widely used in footwear, furniture, clothing, engineering materials, automotive, construction, medical, aerospace, electronic products and other fields.

Because TPU has good impact resistance and shock absorption performance, as well as good wear resistance, it has been widely used in the production of mobile phone protection shell. The biggest advantage of TPU protective shell is good protection, anti-fall, feel good, easy to take, very good elasticity. According to the survey, 90% of iPhone consumers love the TPU case.

During the production process of the TPU protective shell, a neutral or oily release agent (release agent) is sprayed on the mold, so that the release agent is mixed on the product, and the release agent cannot be removed even if the surface is clean before spraying. Clean, resulting in the oil primer after the UV primer, not oil, off Baige and other adverse factors. In response to this problem, Yuanya has developed a pre-painting surface treatment agent for TPU materials. The product performance is mainly to cover the material oil, improve the production yield, and enhance the adhesion of materials and paints. The TPU treatment agent contains the same components as the material, the elastomer resin, so that the combination of the TPU product and the paint not only stays on the surface, but the adhesion of the paint and the product achieves molecular layer penetration, thereby increasing the adhesion. This product has been widely used in mobile phone protection cover TPU vacuum plating process.

Instructions:

First, use as a treatment agent.

Clean the surface of the material with white electric oil

Spray or wipe the TPU treatment agent on the material to be processed (film thickness 3-5μm)

65 degrees bake for 3-5 minutes best

Spray primer

Second, mixed use.

Adding a certain proportion of TPU anti-oil treatment agent mixed with the primer, the effect can improve the leveling, improve adhesion, cover oil, found that this submerged water can also replace the TPU color base, direct color when used as a primer.
