Formula analysis: 7128 bifunctional polyurethane acrylate provides excellent adhesion properties to glass, metal, and ceramics.
AM-327 solidifies quickly and has a larger volume shrinkage than 7128, resulting in shrinkage differences and the formation of wrinkles and cracks.
BP benzophenone accelerates surface drying. Be careful not to add too much to avoid excessive curing and drying of the paint film.
Additives play a role in leveling and defoaming
MP-360 multifunctional aminosilane coupling agent can be photocured, react quickly, and enhance adhesion and water resistance.
Construction technology: 60-80T screen version is suitable to ensure sufficient paint film thickness (about 30-50um)
The drying and curing line speed is about 1-3 meters/min. The power number of the UV lamp and the illumination distance are crucial to the effect of the ice flower. adjust different
Line speed, light power and distance can produce pattern effects of different sizes.
Lighting equipment must ensure adequate ventilation and heat dissipation
The first illumination can create a clear ice cracking effect, the second illumination can produce fine lines and wrinkles, and the third illumination can completely cure the paint film.
Sample test: The ice flower cracks are about 0.5-1.0cm, and the wrinkles are uniform and have a strong three-dimensional effect.
