[0195] 1. Coating composition without catalyst

[0196] The first APO and the second APO were heated and melted in a steel paint can on a hot plate equipped with a three-blade overhead laboratory stirrer. The first APO and the second APO were heated to 160°C-170°C while stirring, and then allowed to cool to 100°C. The bio-based oil is then added to the mixture with the silicone while stirring. The mixture was then heated to 180°C-190°C for 15 minutes while stirring.

Abstract

The present disclosure provides a flooding composition. In an embodiment, the flooding composition includes in weight percent (wt%) based on the weight of the composition (A) from 20 wt% to 40 wt% ofa polyolefin component comprising (i) a first amorphous polyolefin (APO), and (ii) a second APO different than the first APO. The flooding composition also includes (B) from 30 wt% to 60 wt% of a bio-based oil; and (C) from 15 wt% to 45 wt% of a polysiloxane.

Description

Background technique [0001] A flooding composition is a material designed to occupy the void space in a communication cable such as that typically found around and between buffer tubes commonly used in fiber optic cables. Additionally, the coating composition can be used as a filler material to suspend and protect the optical fiber inside the buffer tube. The coating composition is free flowing at elevated temperatures such as those used when filling telecommunication cables, and gels readily at lower temperatures to avoid dripping at room temperature. In addition, an easy-to-clean and non-messy coating composition is desirable for ease of installation and protection from environmental contamination. Although progress has been made in the field of coating compounds, improvements are still needed. [0002] Another important characteristic of the coating composition is its compatibility with the polymeric materials used in the cable construction, such as polyolefins, i.e. low ...
