Impact of weather conditions and formulations on LMW silicone fluid content in RTV silicone rubber coatings
Bibliographic record
Abstract
The presence of sufficient amount of low molecular weight (LMW) silicone fluid in RTV silicone rubber coating is a critical factor in the recovery of the hydrophobicity. In this paper, the effects of wind and water on LMW silicone fluid content in RTV coating are reported. The wind was found to have no effect on the LMW content in RTV coating for up to 20 months in a continuous wind at a speed of 7.45/spl plusmn/0.2 km/h at 23/spl plusmn/3/spl deg/C. LMW silicone fluid was found to dissolve slightly in water after 12 months of immersion in a saline wafer of 70 /spl mu/S/cm at 23/spl plusmn/3/spl deg/C. Alumina trihydrate (ATH), added to RTV to impart resistance to tracking and erosion, also displaced silicone rubber and reduced the available LMW fluid in the coating. The dependence of the content of LMW silicone fluid in RTV on the concentration of ATH was determined. The contact angle was measured to determine the hydrophobicity of the surface of the coating. The hydrophobicity was found to remain unchanged despite long exposure to wind and water and was also independent of the filler concentration in the range 50-150 pph.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
