RTP Co., a global compounder of custom engineered thermoplastics based in Winona, MN, has acquired the patents for nanoparticle-based anti-scratch additives from TenasiTech.

“The base technology greatly improves scratch and mar resistance in injection molded thermoplastics, delivering best-in-class performance,” explained Scott Koberna, General Manager – Wear and Friction at RTP. “We are very excited to include this technology in our expansive Surface Protection portfolio of materials.”

Damage from scratch or mar can occur on the surface of a plastic part during manufacturing, assembly, packaging, shipping, or product use. To protect the aesthetic value of the part, molders and manufacturers often turn to costly secondary processes, such as special protective packaging, coatings, or painting, according to RTP.

Surface Protection Compounds from RTP have the scratch resistance and depth of color required to potentially eliminate the need for these secondary processes, thereby reducing costs, improving aesthetics, and enhancing perceived value of the part. This is particularly helpful for automotive interior and exterior components, consumer products, and medical electronics housings. The company is planning a commercial launch of its TenasiTech Surface Protection portfolio in 2021.

“Our initial integration of the nanoparticle technology will be in polyamide, acrylic, and polyester resin systems,” said Koberna. “We will offer clear grades and can achieve many colors, including the coveted Piano Black hue. Following that, we’ll explore the use of anti-scratch technology for additional thermoplastic polymers and thermoplastic solid coatings, solvent- and water-based coatings, and sheet and film extrusion.”
