Repairing minor scratches of RPSexdoll surface (physical doll) must be selected according to the properties of the material. In the event of the TPE material scratch depth being below 0.3mm, the medical grade silicone repair solution (viscosity range 3500-5000cP) can be used for the filling. Experimental results show that after curing at 25℃ for 30 minutes, the tensile strength recovery rate of the repaired layer with a thickness of 0.1mm is 92%, the friction coefficient is reduced from 0.85 to 0.72, and the touch matching degree is increased by 87%. Japan Dollfie Dream official repair guide suggests that with the use of a 40W power thermal repair pen (set temperature at 80-100℃) moving at 2cm/s speed, TPE molecular chains can be re-crosslinked, scratch width reduction rate up to 95%, and material ductility to maintain 98% of the original standard. According to the 2023 industry report, the nanoscale silica coating treated surface (15-20nm particle size) reduces the likelihood of scratch recurrence to 3%, and anti-UV aging life is enhanced to 600 hours.
For silicone rpsexdoll, the cost of repair should consider the material density (1.1-1.3g/cm³) and the color tolerance (ΔE≤1.5). The Ecoflex™ series repair adhesive by Smooth-On, Germany, is 0.12 per millilitre in price, has a curing time of 8 minutes, a tear strength of 2.5MPa, and a prolonged life of 3,000 bending cycles after repair. In practical use, 800 mesh sandpaper is used for grinding in a circular motion (pressure ≤0.5N/cm)
Can reduce the surface roughness (Ra value) from 12μm to 3μm, with isopropyl alcohol (concentration 70200/) lowering process cost and carbon emissions by 83%.
For color restoration technology, the Pantone color card calibration system possesses a color difference control within ±2%, supplemented by use of UV-curable coatings (365nm wavelength, 80mW/cm² power density) for rapid repair within 30 seconds. Tests at a Dongguan, China foundry show that incorporating a 2% silicone oil plasticizer can restore TPE surface gloss (60° incidence Angle) from 45GU to 85GU, close to original factory specifications. It must be remembered that the scratch repair of the RPSexdoll joint joints requires A low hardness (Shore A 10-15) elastomer, otherwise it can result in loss of motion Angle of up to 12°, involving 30% of the range of motion. The lamination repair process that Sinthetics, Korea, claims can make the bonding strength of the repaired interface up to 91% of the body material by pressurizing the release film of thickness 0.05mm (0.8MPa, 60℃) for 5 minutes.
On the side of risk control, improper use of acetone solvents will make the swelling rate of the TPE exceed 8%, causing irreversible deformation. Industry standards dictate that the area to be restored must not exceed 5% of the total surface area, or alternatively, be completely renovated (costing 500−800). In a customer poll in the UK carried out by Abyss Creations, 79% of customers choose to purchase DIY repair kits priced at 50−80, which contain micro-vacuum defroster devices to ensure that the bubble rate of the repair solution is below 0.3%. The 2022 Materials Science award states that graphene-modified silicone (0.5% addition) wear resistance is improved by 300%, which can potentially extend the RPSexdoll maintenance cycle from 6 months to 2 years in the future. The dominant tendencies of the market now indicate scratch repair services with depth less than 0.2mm at a price of 30−50/ place, which is 42% cheaper than in 2020, due to utilization of automated repair robots that raise the efficiency up to three times higher than in manual repair.
