# Antidegradants in DIY Compounds: Retarding Failure You Cannot Prevent

> **Not a recipe article.** phr tables live in Deep dives. More antioxidant is not always better—staining, bloom, and cost trade-offs are real.

## Executive summary

Handbook law: latex article **degradation cannot be prevented—only retarded**; heat, humidity, UV, ozone, oxygen, oils, metals, and stress co-drive failure [^2]. **Liquid latex work** DIY compounds for wearable film should plan **0.5–2 phr antioxidant** for thin goods, with amine vs phenolic stain trade-offs [^3]. Use this when compounding Path B sheet intended to last beyond a single event—after reading [Aging, Storage and Care](/literature-reviews/aging-storage-and-care).

## The retardation law

Degradation **cannot be prevented—only retarded**; drivers include heat, humidity, UV, ozone, oxygen, chemicals, and stress [^2]. Three oxidative modes: chain scission (soft/tack), crosslinking (harden), chemical alteration [^4].

Ozone cracks **oriented** and **widespread**; flex cracks oriented but **local**; UV cracks **non-oriented** over exposed area [^5].

## DIY compounding budget (liquid latex work)

Add efficient antioxidant to most latex compounds, typically **0.5–2 phr**, especially thin-walled products [^3]. Most latex products use **1–2.0 phr total antioxidant** [^6]. Amine antioxidants more effective but **discolor**; phenolics less effective but lower stain [^7].

Match antidegradant package to storage + wear environment per [Aging, Storage and Care](/literature-reviews/aging-storage-and-care) [^8].

<summary>Deep dive: Ozone vs wax vs PPD strategies</summary>

Microcrystalline wax **0.5–1.0 phr**: static ozone barrier; flex cracks bloom [^11]. PPD-type antiozonants **≥2 phr**, often **3 phr** for **dynamic** ozone [^11].

<summary>Deep dive: Warehouse heat stacking (8× aging)</summary>

Oxidation rate doubles per **8.3 °C** rise → ceiling stock can age **~8×** floor stock [^13].
