01 · PRINCIPLE & RATIONALE

Intended function
and associated requirement.

PRINCIPLE

AeroSkin does not claim to eliminate condensation; it changes what happens precisely where the fingers need to generate friction.

WHY IT IS INCLUDED

Three recesses guide the grip, while an air pocket, microtexture and drainage reduce retained water film and the sensation of slipperiness.

DETAILED DESCRIPTION

Reduces retained water in the grip zone through local insulation, microtexture and drainage. A microcellular PHBH membrane is perimeter-sealed over a local air pocket. A solid PLA/carnauba topcoat modifies wetting and droplet movement without free oil. The −60% target refers to retained water versus a control wall at 25 °C / 60% RH with 4 °C water; it does not mean the surface will always remain dry.

02 · TECHNOLOGY STACK

Technologies, roles
and approval gates.

T-01

Sealed air pocket

Role: Interrupts the local thermal path through the grip zone.
Why: Reduces surface cooling without insulating the entire bottle.
Approval gate: Micro-CT, leak testing and 4/40 °C cycling.

T-02

Microcellular PHBH

Role: Creates a compressible, microtextured membrane.
Why: Adds grip and drainage with limited mass.
Approval gate: Density, cell size, abrasion and peel.

T-03

Immobilised PLA/carnauba topcoat

Role: Changes wetting and droplet movement.
Why: Avoids free oil and transfer to the hand.
Approval gate: Migration, white-paper transfer and sliding angle.

04 · MASTER PARAMETER REGISTER

Everything to be defined,
measured or certified.

A field without evidence is never filled with an invented number: it remains “To be determined”, together with the method required to close it. This is what makes the technical record verifiable.

08 · EVIDENCE POLICY

Traceability
for every parameter.

The system favours components from the same polymer family and a micrometre-scale solid coating. Compatibility with PHA recovery or treatment must be demonstrated on the complete assembly.

This page is the technical register for the R2 configuration. It separates design values, targets, calculations, measurements and certifications. Open fields identify the exact test or document required to close them.
